Abstract
Air pollution contributes to the premature deaths of millions of people each year around the world, and air quality problems are growing in many developing nations. While past policy efforts have succeeded in reducing particulate matter and trace gases in North America and Europe, adverse health effects are found at even these lower levels of air pollution. Future policy actions will benefit from improved understanding of the interactions and health effects of different chemical species and source categories. Achieving this new understanding requires air pollution scientists and engineers to work increasingly closely with health scientists. In particular, research is needed to better understand the chemical and physical properties of complex air pollutant mixtures, and to use new observations provided by satellites, advanced in situ measurement techniques, and distributed micro monitoring networks, coupled with models, to better characterize air pollution exposure for epidemiological and toxicological research, and to better quantify the effects of specific source sectors and mitigation strategies.

Synopsis
Air pollution contributes to the premature deaths of millions of people each year around the world, and air quality problems are growing in many developing nations. While past policy efforts have succeeded in reducing particulate matter and trace gases in North America and Europe, adverse health effects are found at even these lower levels of air pollution. Future policy actions will benefit from improved understanding of the interactions and health effects of different chemical species and source categories. Achieving this new understanding requires air pollution scientists and engineers to work increasingly closely with health scientists. In particular, research is needed to better understand the chemical and physical properties of complex air pollutant mixtures, and to use new observations provided by satellites, advanced in situ measurement techniques, and distributed micro monitoring networks, coupled with models, to better characterize air pollution exposure for epidemiological and toxicological research, and to better quantify the effects of specific source sectors and mitigation strategies.
Introduction
What specific characteristics and components of air pollution, or specific mixtures of air pollutants, are responsible for specific health effects?
How important are certain source sectors and source regions for air pollution health effects in a particular location, region, or globally?
Would other indicators of complex air pollution mixtures and their interactions with human health be more effective for future air quality management?
What are the human health implications of alternative future strategies for emissions controls and energy use?

(Lippincott Williams & Wilkins)A review. In 2004, the first American Heart Assocn. scientific statement on "Air Pollution and Cardiovascular Disease" concluded that exposure to particulate matter (PM) air pollution contributes to cardiovascular morbidity and mortality. In the interim, numerous studies have expanded our understanding of this assocn. and further elucidated the physiol. and mol. mechanisms involved. The main objective of this updated American Heart Assocn. scientific statement is to provide a comprehensive review of the new evidence linking PM exposure with cardiovascular disease, with a specific focus on highlighting the clin. implications for researchers and healthcare providers. The writing group also sought to provide expert consensus opinions on many aspects of the current state of science and updated suggestions for areas of future research. On the basis of the findings of this review, several new conclusions were reached, including the following: Exposure to PM < 2.5 μm in diam. (PM2.5) over a few hours to weeks can trigger cardiovascular disease-related mortality and nonfatal events; longer-term exposure (eg, a few years) increases the risk for cardiovascular mortality to an even greater extent than exposures over a few days and reduces life expectancy within more highly exposed segments of the population by several months to a few years; redns. in PM levels are assocd. with decreases in cardiovascular mortality within a time frame as short as a few years; and many credible pathol. mechanisms have been elucidated that lend biol. plausibility to these findings. It is the opinion of the writing group that the overall evidence is consistent with a causal relationship between PM2.5 exposure and cardiovascular morbidity and mortality. This body of evidence has grown and been strengthened substantially since the first American Heart Assocn. scientific statement was published. Finally, PM2.5 exposure is deemed a modifiable factor that contributes to cardiovascular morbidity and mortality.

However, adequate direct evidence to identify the shape of the mortality RR functions at the high ambient concentrations observed in many places in the world is lacking. OBJECTIVE: We developed RR functions over the entire global exposure range for causes of mortality in adults: ischemic heart disease (IHD), cerebrovascular disease (stroke), chronic obstructive pulmonary disease (COPD), and lung cancer (LC). We also developed RR functions for the incidence of acute lower respiratory infection (ALRI) that can be used to estimate mortality and lost-years of healthy life in children < 5 years of age. METHODS: We fit an integrated exposure-response (IER) model by integrating available RR information from studies of ambient air pollution (AAP), second hand tobacco smoke, household solid cooking fuel, and active smoking (AS). AS exposures were converted to estimated annual PM2.5 exposure equivalents using inhaled doses of particle mass. We derived population attributable fractions (PAFs) for every country based on estimated worldwide ambient PM2.5 concentrations. RESULTS: The IER model was a superior predictor of RR compared with seven other forms previously used in burden assessments. The percent PAF attributable to AAP exposure varied among countries from 2 to 41 for IHD, 1 to 43 for stroke, < 1 to 21 for COPD, < 1 to 25 for LC, and < 1 to 38 for ALRI. CONCLUSIONS: We developed a fine particulate mass-based RR model that covered the global range of exposure by integrating RR information from different combustion types that generate emissions of particulate matter. The model can be updated as new RR information becomes available.

Risk factor quantification, particularly of modifiable risk factors, can help to identify emerging threats to population health and opportunities for prevention. The GBD 2013 provides a timely opportunity to update the comparative risk assessment with new data for exposure, relative risks, and evidence on the appropriate counterfactual risk distribution. METHODS: Attributable deaths, years of life lost, years lived with disability, and disability-adjusted life-years (DALYs) have been estimated for 79 risks or clusters of risks using the GBD 2010 methods. Risk-outcome pairs meeting explicit evidence criteria were assessed for 188 countries for the period 1990-2013 by age and sex using three inputs: risk exposure, relative risks, and the theoretical minimum risk exposure level (TMREL). Risks are organised into a hierarchy with blocks of behavioural, environmental and occupational, and metabolic risks at the first level of the hierarchy. The next level in the hierarchy includes nine clusters of related risks and two individual risks, with more detail provided at levels 3 and 4 of the hierarchy. Compared with GBD 2010, six new risk factors have been added: handwashing practices, occupational exposure to trichloroethylene, childhood wasting, childhood stunting, unsafe sex, and low glomerular filtration rate. For most risks, data for exposure were synthesised with a Bayesian meta-regression method, DisMod-MR 2.0, or spatial-temporal Gaussian process regression. Relative risks were based on meta-regressions of published cohort and intervention studies. Attributable burden for clusters of risks and all risks combined took into account evidence on the mediation of some risks such as high body-mass index (BMI) through other risks such as high systolic blood pressure and high cholesterol. FINDINGS: All risks combined account for 57·2% (95% uncertainty interval [UI] 55·8-58·5) of deaths and 41·6% (40·1-43·0) of DALYs. Risks quantified account for 87·9% (86·5-89·3) of cardiovascular disease DALYs, ranging to a low of 0% for neonatal disorders and neglected tropical diseases and malaria. In terms of global DALYs in 2013, six risks or clusters of risks each caused more than 5% of DALYs: dietary risks accounting for 11·3 million deaths and 241·4 million DALYs, high systolic blood pressure for 10·4 million deaths and 208·1 million DALYs, child and maternal malnutrition for 1·7 million deaths and 176·9 million DALYs, tobacco smoke for 6·1 million deaths and 143·5 million DALYs, air pollution for 5·5 million deaths and 141·5 million DALYs, and high BMI for 4·4 million deaths and 134·0 million DALYs. Risk factor patterns vary across regions and countries and with time. In sub-Saharan Africa, the leading risk factors are child and maternal malnutrition, unsafe sex, and unsafe water, sanitation, and handwashing. In women, in nearly all countries in the Americas, north Africa, and the Middle East, and in many other high-income countries, high BMI is the leading risk factor, with high systolic blood pressure as the leading risk in most of Central and Eastern Europe and south and east Asia. For men, high systolic blood pressure or tobacco use are the leading risks in nearly all high-income countries, in north Africa and the Middle East, Europe, and Asia. For men and women, unsafe sex is the leading risk in a corridor from Kenya to South Africa. INTERPRETATION: Behavioural, environmental and occupational, and metabolic risks can explain half of global mortality and more than one-third of global DALYs providing many opportunities for prevention. Of the larger risks, the attributable burden of high BMI has increased in the past 23 years. In view of the prominence of behavioural risk factors, behavioural and social science research on interventions for these risks should be strengthened. Many prevention and primary care policy options are available now to act on key risks. FUNDING: Bill & Melinda Gates Foundation.

(American Chemical Society)Ambient air pollution exposure is a major risk factor for global disease. Assessing the impact of air pollution on population health and evaluating trends relative to other major risk factors requires regularly updated, accurate, spatially resolved exposure ests. This work combined satellite-based ests., chem. transport model simulations, and ground measurements from 79 countries to produce global ests. of annual av. fine particle (PM2.5) and O3 concns. at 0.1° × 0.1° spatial resoln. for 5-yr intervals from 1990 to 2010 and year 2013. These ests. were used to assess population-weighted mean concns. for 1990-2013 for 188 countries. In 2013, 87% of the world population lived in areas exceeding the World Health Organization air quality guideline (10 μg/m3 PM2.5 annual av.). From 1990 to 2013, global population-weighted PM2.5 increased 20.4%, driven by trends in southern and southeastern Asia and China. Decreases in population-weighted mean PM2.5 concns. were evident in most high income countries. Population-weighted mean O3 concns. increased globally 8.9% from 1990 to 2013, with increases in most countries; modest decreases occurred in North America, parts of Europe, and several southeastern Asia countries.

(American Chemical Society)Ambient fine particulate matter (PM2.5) has a large, well-documented global burden of disease. This work used high-resoln. (10 km, global-coverage) concn. data and cause-specific integrated exposure-response functions developed for the Global Burden of Disease 2010 to assess how regional and global improvements in ambient air quality could reduce attributable mortality from PM2.5. Overall, an aggressive global program of PM2.5 mitigation in accord with World Health Organization interim guidelines could avoid 750,000 (23%) of the 3.2 million deaths/yr currently (2010) attributable to ambient PM2.5. Modest improvements in PM2.5 in relatively clean regions (North America, Europe) would result in surprisingly large avoided mortality, due to demog. factors and the non-linear concn.-response relationship which describes the risk of PM in relation to several important causes of death. Major air quality improvements would be required to substantially reduce mortality from PM2.5 in more polluted regions, e.g., China and India. Forecasted demog. and epidemiol. transitions in India and China imply that to maintain PM2.5-attributable mortality rates (deaths/100,000 people-yr) const., av. PM2.5 concns. would need to decline by ∼20-30% over the next 15 years to merely offset increases in PM2.5-attributable mortality from aging populations. An effective program to deliver clean air to the most polluted regions could avoid several hundred thousand premature deaths each year.

(Air & Waste Management Association)A review. In celebration of the 100th anniversary of the Air & Waste Management Assocn., this review examines the history of air quality management (AQM) in the United States over the last century, with an emphasis on the ambient stds. programs established by the landmark 1970 Clean Air Act (CAA) Amendments. The current CAA system is a hybrid of several distinct air pollution control philosophies, including the recursive or circular system driven by ambient stds. Although this evolving system has resulted in tremendous improvements in air quality, it has been far from perfect in terms of timeliness and effectiveness. The paper looks at several periods in the history of the U.S. program, including:. (1) 1900-1970, Spanning the early smoke abatement and smog control programs, the first federal involvement, and the development of a hybrid AQM approach in the 1970 CAA;. (2) 1971-1976, When the first National Ambient Air Quality Stds. (NAAQS) were set and implemented;. (3) 1977-1993, A period of the first revisions to the stds., new CAA Amendments, delays in implementation and decision-making, and key science/policy/legislative developments that would alter both the focus and scale of air pollution programs and how they are implemented; and. (4) 1993-2006, The second and third wave of NAAQS revisions and their implementation in the context of the 1990 CAA. This discussion examines where NAAQS have helped drive implementation programs and how improvements in both effects and air quality/control sciences influenced policy and legislation to enhance the effectiveness of the system over time. The review concludes with a look toward the future of AQM, emphasizing challenges and ways to meet them. The most significant of these is the need to make more efficient progress toward air quality goals, while adjusting the system to address the growing intersections between air quality management and climate change.

(Massachusetts Medical Society)Exposure to fine-particulate air pollution has been assocd. with increased morbidity and mortality, suggesting that sustained redns. in pollution exposure should result in improved life expectancy. This study directly evaluated the changes in life expectancy assocd. with differential changes in fine-particulate air pollution that occurred in the United States during the 1980s and 1990s. The authors compiled data on life expectancy, socioeconomic status, and demog. characteristics for 211 county units in the 51 U.S. metropolitan areas with matching data on fine-particulate air pollution for the late 1970s and early 1980s and the late 1990s and early 2000s. Regression models were used to est. the assocn. between redns. in pollution and changes in life expectancy, with adjustment for changes in socioeconomic and demog. variables and in proxy indicators for the prevalence of cigarette smoking. A decrease of 10 μg per cubic meter in the concn. of fine particulate matter was assocd. with an estd. increase in mean (± SE) life expectancy of 0.61 ± 0.20 yr (P = 0.004). The estd. effect of reduced exposure to pollution on life expectancy was not highly sensitive to adjustment for changes in socioeconomic, demog., or proxy variables for the prevalence of smoking or to the restriction of observations to relatively large counties. Redns. in air pollution accounted for as much as 15% of the overall increase in life expectancy in the study areas. A redn. in exposure to ambient fine-particulate air pollution contributed to significant and measurable improvements in life expectancy in the United States.

(American Chemical Society)Ambient fine particulate matter (PM2.5) is a leading environmental risk factor for premature mortality. This work used aerosol optical depth (AOD) measurements from 2 satellite instruments, multi-angle imaging spectroradiometer and sea viewing wide field of vision sensor, to produce a unified 15-yr global time series (1998-2012) of ground-level PM2.5 concns. at a 1° x 1° resoln. The GEOS-chem chem. transport model related each individual AOD retrieval to ground-level PM2.5 concn. Four broad areas displaying significant, spatially coherent, annual trends were examd. in detail: eastern USA (-0.39 ± 0.10 μg/m3-yr), Arabian Peninsula (0.81 ± 0.21 μg/m3-yr), southern Asia (0.93 ± 0.22 μg/m3-yr), and eastern Asia (0.79 ± 0.27 μg/m3-yr). Over the dense in-situ observation period, 1999-2012, the linear tendency for the eastern USA (-0.37 ± 0.13 μg/m3-yr) agreed well with in-situ measurements (-0.38 ± 0.06 μg/m3-yr). A GEOS-Chem simulation showed secondary inorg. aerosols largely explained the obsd. PM2.5 trend over the eastern USA and southern and eastern Asia; mineral dust largely explained the obsd. trend over the Arabian Peninsula.

(Springer)In Jan. 2013, a long-lasting episode of severe haze occurred in central and eastern China, and it attracted attention from all sectors of society. The process and evolution of haze pollution episodes were obsd. by the "Forming Mechanism and Control Strategies of Haze in China" group using an intensive aerosol and trace gases campaign that simultaneously obtained data at 11 ground-based observing sites in the CARE-China network. The characteristics and formation mechanism of haze pollution episodes were discussed. Five haze pollution episodes were identified in the Beijing-Tianjin-Hebei (Jing-Jin-Ji) area; the two most severe episodes occurred during 9-15 Jan. and 25-31 Jan. During these two haze pollution episodes, the max. hourly PM2.5 mass concns. in Beijing were 680 and 530 μg m-3, resp. The process and evolution of haze pollution episodes in other major cities in the Jing-Jin-Ji area, such as Shijiazhuang and Tianjin were almost the same as those obsd. in Beijing. The external cause of the severe haze episodes was the unusual atm. circulation, the depression of strong cold air activities and the very unfavorable dispersion due to geog. and meteorol. conditions. However, the internal cause was the quick secondary transformation of primary gaseous pollutants to secondary aerosols, which contributed to the "explosive growth" and "sustained growth" of PM2.5. Particularly, the abnormally high amt. of nitric oxide (NOx) in the haze episodes, produced by fossil fuel combustion and vehicle emissions, played a direct or indirect role in the quick secondary transformation of coal-burning sulfur dioxide (SO2) to sulfate aerosols. Furthermore, gaseous pollutants were transformed into secondary aerosols through heterogeneous reactions on the surface of fine particles, which can change the particle's size and chem. compn. Consequently, the proportion of secondary inorg. ions, such as sulfate and nitrate, gradually increased, which enhances particle hygroscopicity and thereby accelerating formation of the haze pollution.

(Wiley-Blackwell)This anal. provides an up-to-date assessment of long-term (1990-2010) rural ozone trends using all available data in the Western (12 sites) and Eastern (41 sites) USA. Rather than focus solely on av. ozone values or air quality std. violations, we consider the full range of ozone values, reporting trends for the 5th, 50th and 95th percentiles. Domestic ozone precursor emissions decreased strongly during 1990-2010. Accordingly 83%, 66% and 20% of summertime eastern U.S. sites experienced statistically significant ozone decreases in the 95th, 50th and 5th percentiles, resp. During spring 43% of the eastern sites have statistically significant ozone decreases for the 95th percentile with no sites showing a significant increase. At the 50th percentile there is little overall change in the Eastern U.S. In contrast, only 17% (2 sites) and 8% (1 site) of summertime Western U.S. sites have statistically significant ozone decreases in the 95th and 50th percentiles, resp. During spring no western site has a significant decrease, while 50% have a significant median increase. This dichotomy in U.S. ozone trends is discussed in terms of changing anthropogenic and biomass burning emissions. Consideration is given to the concept that increasing baseline ozone flowing into the western U.S. is counteracting ozone redns. due to domestic emission redns. An update to the springtime free tropospheric ozone trend above western North America shows that ozone has increased significantly from 1995 to 2011 at the rate of 0.41 ± 0.27 ppbv yr-1. Finally, the ozone changes are examd. in relation to regional temp. trends.

P.Atmospheric Chemistry and Physics (2013), 13 (8), 4145-4169, 25 pp.CODEN: ACPTCE; ISSN:1680-7324. (Copernicus Publications)Tropospheric NO2, a key pollutant in particular in cities, has been measured from space since the mid-1990s by the GOME, SCIAMACHY, OMI, and GOME-2 instruments. These data provide a unique global long-term dataset of tropospheric pollution. However, the observations differ in spatial resoln., local time of measurement, viewing geometry, and other details. All these factors can severely impact the retrieved NO2 columns. In this study, we present three ways to account for instrumental differences in trend analyses of the NO2 columns derived from satellite measurements, while preserving the individual instruments' spatial resolns. For combining measurements from GOME and SCIAMACHY into one consistent time series, we develop a method to explicitly account for the instruments' difference in ground pixel size (40 × 320 km2 vs. 30 × 60 km2). This is esp. important when analyzing NO2 changes over small, localised sources like, e.g. megacities. The method is based on spatial averaging of the measured earthshine spectra and extn. of a spatial pattern of the resoln. effect. Furthermore, two empirical corrections, which summarise all instrumental differences by including instrument-dependent offsets in a fitted trend function, are developed. These methods are applied to data from GOME and SCIAMACHY sep., to the combined time series, and to an extended dataset comprising also GOME-2 and OMI measurements. All approaches show consistent trends of tropospheric NO2 for a selection of areas on both regional and city scales, for the first time allowing consistent trend anal. of the full time series at high spatial resoln. Compared to previous studies, the longer study period leads to significantly reduced uncertainties. We show that measured tropospheric NO2 columns have been strongly increasing over China, the Middle East, and India, with values over east-central China tripling from 1996 to 2011. All parts of the developed world, including Western Europe, the United States, and Japan, show significantly decreasing NO2 amts. in the same time period. On a megacity level, individual trends can be as large as +27.2 ± 3.9 %yr-1 and +20.7 ± 1.9 %yr-1 in Dhaka and Baghdad, resp., while Los Angeles shows a very strong decrease of -6.00 ± 0.72 %yr-1. Most megacities in China, India, and the Middle East show increasing NO2 columns of +5 to 10 %yr-1, leading to a doubling to tripling within the study period.

(U. S. Department of Health and Human Services, National Institutes of Health)Background: Air pollution is assocd. with morbidity and premature mortality. Satellite remote sensing provides globally consistent decadal-scale observations of ambient nitrogen dioxide (NO2) pollution. Objective: We detd. global population-weighted annual mean NO2 concns. from 1996 through 2012. Methods: We used observations of NO2 tropospheric column densities from three satellite instruments in combination with chem. transport modeling to produce a global 17-yr record of ground-level NO2 at 0.1 ° × 0.1 ° resoln. We calcd. linear trends in population-weighted annual mean NO2 (PWMNO2) concns. in different regions around the world. Results: We found that PWMNO2 in high-income North America (Canada and the United States) decreased more steeply than in any other region, having declined at a rate of -4.7%/yr [95% confidence interval (CI): -5.3, -4.1]. PWMNO2 decreased in western Europe at a rate of -2.5%/yr (95% CI: -3.0, -2.1). The highest PWMNO2 occurred in high-income Asia Pacific (predominantly Japan and South Korea) in 1996, with a subsequent decrease of -2.1%/yr (95% CI: -2.7, -1.5). In contrast, PWMNO2 almost tripled in East Asia (China, North Korea, and Taiwan) at a rate of 6.7%/yr (95% CI: 6.0, 7.3). The satellite-derived ests. of trends in ground-level NO2 were consistent with regional trends inferred from data obtained from ground-station monitoring networks in North America (within 0.7%/yr) and Europe (within 0.3%/yr). Our rankings of regional av. NO2 and long-term trends differed from the satellite-derived ests. of fine particulate matter reported elsewhere, demonstrating the utility of both indicators to describe changing pollutant mixts. Conclusions: Long-term trends in satellite-derived ambient NO2 provide new information about changing global exposure to ambient air pollution.

After increasing until about 2006, we est. a declining trend continuing until 2011. However, there is strong spatial variability, with North America and Europe continuing to reduce emissions, with an increasing role of Asia and international shipping. China remains a key contributor, but the introduction of stricter emission limits followed by an ambitious program of installing flue gas desulfurization on power plants resulted in a significant decline in emissions from the energy sector and stabilization of total Chinese SO2 emissions. Comparable mitigation strategies are not yet present in several other Asian countries and industrial sectors in general, while emissions from international shipping are expected to start declining soon following an international agreement to reduce the sulfur content of fuel oil.

(IOP Publishing Ltd.)Emissions of gases and particles from the combustion of fossil fuels and biofuels in Africa are expected to increase significantly in the near future due to the rapid growth of African cities and megacities. There is currently no regional emissions inventory that provides ests. of anthropogenic combustion for the African continent. This work provides a quantification of the evolution of African combustion emissions from 2005 to 2030, using a bottom-up method. This inventory predicts very large increases in black carbon, org. carbon, CO, NOx, SO2 and non-methane hydrocarbon emissions if no emission regulations are implemented. This paper discusses the effectiveness of scenarios involving certain fuels, specific to Africa in each activity sector and each region (western, eastern, northern and southern Africa), to reduce the emissions. The estd. trends in African emissions are consistent with emissions provided by global inventories, but they display a larger range of values. African combustion emissions contributed significantly to global emissions in 2005. This contribution will increase more significantly by 2030: org. carbon emissions will for example make up 50% of the global emissions in 2030. Furthermore, we show that the magnitude of African anthropogenic emissions could be similar to African biomass burning emissions around 2030.

(Taylor & Francis Ltd.)Multiple linkages connect air quality and climate change. Many air pollutant sources also emit carbon dioxide (CO2), the dominant anthropogenic greenhouse gas (GHG). The two main contributors to non-attainment of U. S. ambient air quality stds., ozone (O3) and particulate matter (PM), interact with radiation, forcing climate change. PM warms by absorbing sunlight (e.g., black carbon) or cools by scattering sunlight (e.g., sulfates) and interacts with clouds; these radiative and microphys. interactions can induce changes in pptn. and regional circulation patterns. Climate change is expected to degrade air quality in many polluted regions by changing air pollution meteorol. (ventilation and diln.), pptn. and other removal processes, and by triggering some amplifying responses in atm. chem. and in anthropogenic and natural sources. Together, these processes shape distributions and extreme episodes of O3 and PM. Global modeling indicates that as air pollution programs reduce SO2 to meet health and other air quality goals, near-term warming accelerates due to "unmasking" of warming induced by rising CO2. Air pollutant controls on CH4, a potent GHG and precursor to global O3 levels, and on sources with high black carbon (BC) to org. carbon (OC) ratios could offset near-term warming induced by SO2 emission redns., while reducing global background O3 and regionally high levels of PM. Lowering peak warming requires decreasing atm. CO2, which for some source categories would also reduce co-emitted air pollutants or their precursors. Model projections for alternative climate and air quality scenarios indicate a wide range for U. S. surface O3 and fine PM, although regional projections may be confounded by interannual to decadal natural climate variability. Continued implementation of U. S. NOx emission controls guards against rising pollution levels triggered either by climate change or by global emission growth. Improved accuracy and trends in emission inventories are crit. for accountability analyses of historical and projected air pollution and climate mitigation policies. Implications: The expansion of U. S. air pollution policy to protect climate provides an opportunity for joint mitigation, with CH4 a prime target. BC redns. in developing nations would lower the global health burden, and for BC-rich sources (e.g., diesel) may lessen warming. Controls on these emissions could offset near-term warming induced by health-motivated redns. of sulfate (cooling). Wildfires, dust, and other natural PM and O3 sources may increase with climate warming, posing challenges to implementing and attaining air quality stds. Accountability analyses for recent and projected air pollution and climate control strategies should underpin estd. benefits and trade-offs of future policies.

(National Academy of Sciences)Recent bursts in the incidence of large wildfires worldwide have raised concerns about the influence climate change and humans might have on future fire activity. Comparatively little is known, however, about the relative importance of these factors in shaping global fire history. Here we use fire and climate modeling, combined with land cover and population ests., to gain a better understanding of the forces driving global fire trends. Our model successfully .reproduces global fire activity record over the last millennium and reveals distinct regimes in global fire behavior. We find that during the preindustrial period, the global fire regime was strongly driven by pptn. (rather than temp.), shifting to an anthropogenic-driven regime with the Industrial Revolution. Our future projections indicate an impending shift to a temp.-driven global fire regime in the 21st century, creating an unprecedentedly fire-prone environment. These results suggest a possibility that in the future climate will play a considerably stronger role in driving global fire trends, outweighing direct human influence on fire (both ignition and suppression), a reversal from the situation during the last two centuries.

(VOCs) in air with a high sensitivity and a fast time response. The use of PTR-MS in atm. research has expanded rapidly in recent years, and much has been learned about the instrument response and specificity of the technique in the anal. of air from different regions of the atm. This paper aims to review the progress that has been made. The theory of operation is described and allows the response of the instrument to be described for different operating conditions. More accurate detns. of the instrument response involve calibrations using std. mixts., and some results are shown. Much has been learned about the specificity of PTR-MS from inter-comparison studies as well the coupling of PTR-MS with a gas chromatog. interface. The literature on this issue is reviewed and summarized for many VOCs of atm. interest. Some highlights of airborne measurements by PTR-MS are presented, including the results obtained in fresh and aged forest-fire and urban plumes. Finally, the recent work that is focused on improving the technique is discussed.

A unifying model framework describing the atm. evolution of OA which is constrained by high time resolved measurements of its compn., volatility, and oxidn. state is presented. OA and OA precursor gases evolve by becoming increasingly oxidized, less volatile, and more hygroscopic, leading to the formation of oxygenated org. aerosols (OOA), with concns. comparable to those of SO42- aerosols throughout the Northern Hemisphere. This model framework captures the dynamic aging behavior obsd. in the atm. and lab.; it serves as a basis to improve regional and global model parameterizations.

(Nature Publishing Group)Heterogeneous reactions of O3 with aerosol particles are of central importance to air quality. They are studied extensively, but mol. mechanisms and kinetics are unresolved. Based on new exptl. data and calcns., this work showed long-lived reactive O intermediates (ROI) are formed. The chem. lifetime of these intermediates is >100 s, much longer than the surface residence time of mol. O3 (∼10-9 s). ROI explain and resolve apparent discrepancies between earlier quantum mech. calcns. and kinetic expts. They play a key role in the chem. transformation and adverse health effects of toxic, allergenic airborne particulate matter, e.g., soot, polycyclic arom. hydrocarbons, and proteins. ROI may also be involved in the decompn. of O3 on mineral dust and in formation and growth of secondary org. aerosols. Also, ROI may contribute to the coupling of atm. and biospheric multi-phase processes.

(Copernicus Publications)We assess the potential of the water-sol. fraction of atm. fine aerosols in the Southeastern United States to generate reactive oxygen species (ROS) and identify major ROS-assocd. emission sources. ROS-generation potential of particles was quantified by the dithiothreitol (DTT) assay and involved anal. of fine particulate matter (PM) extd. from high-vol. quartz filters (23 h integrated samples) collected at various sites in different environmental settings in the southeast, including three urban-Atlanta sites, in addn. to a rural site. Paired sampling was conducted with one fixed site in Atlanta (Jefferson Street), representative of the urban environment, with the others rotating among different sites, for ∼250 days between June 2012 and Sept. 2013 (N = 483). A simple linear regression between the DTT activity and aerosol chem. components revealed strong assocns. between PM ROSgeneration potential and secondary org. aerosol (WSOC - water-sol. org. carbon) in summer, and biomass burning markers in winter. Redox-active metals were also somewhat correlated with the DTT activity, but mostly at urban and roadside sites. Pos. matrix factorization (PMF) was applied to apportion the relative contribution of various sources to the ROS-generation potential of water-sol. PM2.5 in urban Atlanta. PMF showed that vehicular emissions contribute uniformly throughout the year (12-25 %), while secondary oxidn. processes dominated the DTT activity in summer (46%) and biomass burning in winter (47%). Road dust was significant only during drier periods (∼12% in summr and fall). Source apportionment by chem. mass balance (CMB) was reasonably consistent with PMF, but with higher contribution from vehicular emissions (32%). Given the spatially large data set of PM sampled over an extended period, the study reconciles the results from previous work that showed only region- or season-specific aerosol components or sources contributing to PM ROS activity, possibly due to smaller sample sizes. The ubiquitous nature of the major sources of PM-assocd. ROS suggests widespread population exposures to aerosol components that have the ability to catalyze the prodn. of oxidants in vivo.

Performance was similar to that reported for conventional LUR models of NO2 and NO in this region (116 sites) and better than that for mean σap from fixed-location samplers (25 sites). Models of the mean, 75th, and 90th percentiles favored predictors describing truck, rather than total, traffic.

L.Atmospheric Environment (2013), 70 (), 186-203CODEN: AENVEQ; ISSN:1352-2310. (Elsevier Ltd.)Measurements at appropriate spatial and temporal scales are essential for understanding and monitoring spatially heterogeneous environments with complex and highly variable emission sources, such as in urban areas. However, the costs and complexity of conventional air quality measurement methods means that measurement networks are generally extremely sparse. In this paper we show that miniature, low-cost electrochem. gas sensors, traditionally used for sensing at parts-per-million (ppm) mixing ratios can, when suitably configured and operated, be used for parts-per-billion (ppb) level studies for gases relevant to urban air quality. Sensor nodes, in this case consisting of multiple individual electrochem. sensors, can be low-cost and highly portable, thus allowing the deployment of scalable high-d. air quality sensor networks at fine spatial and temporal scales, and in both static and mobile configurations. In this paper we provide evidence for the performance of electrochem. sensors at the parts-per-billion level, and then outline results obtained from deployments of networks of sensor nodes in both an autonomous, high-d., static network in the wider Cambridge (UK) area, and as mobile networks for quantification of personal exposure. Examples are presented of measurements obtained with both highly portable devices held by pedestrians and cyclists, and static devices attached to street furniture. The widely varying mixing ratios reported by this study confirm that the urban environment cannot be fully characterised using sparse, static networks, and that measurement networks with higher resoln. (both spatially and temporally) are required to quantify air quality at the scales which are present in the urban environment. We conclude that the instruments described here, and the low-cost/high-d. measurement philosophy which underpins it, have the potential to provide a far more complete assessment of the high-granularity air quality structure generally obsd. in the urban environment, and could ultimately be used for quantification of human exposure as well as for monitoring and legislative purposes.

OBJECTIVE: In this study, we developed improved global exposure estimates of ambient PM2.5 mass and trend using PM2.5 concentrations inferred from multiple satellite instruments. METHODS: We combined three satellite-derived PM2.5 sources to produce global PM2.5 estimates at about 10 km × 10 km from 1998 through 2012. For each source, we related total column retrievals of aerosol optical depth to near-ground PM2.5 using the GEOS-Chem chemical transport model to represent local aerosol optical properties and vertical profiles. We collected 210 global ground-based PM2.5 observations from the literature to evaluate our satellite-based estimates with values measured in areas other than North America and Europe. RESULTS: We estimated that global population-weighted ambient PM2.5 concentrations increased 0.55 μg/m3/year (95% CI: 0.43, 0.67) (2.1%/year; 95% CI: 1.6, 2.6) from 1998 through 2012. Increasing PM2.5 in some developing regions drove this global change, despite decreasing PM2.5 in some developed regions. The estimated proportion of the population of East Asia living above the World Health Organization (WHO) Interim Target-1 of 35 μg/m3 increased from 51% in 1998-2000 to 70% in 2010-2012. In contrast, the North American proportion above the WHO Air Quality Guideline of 10 μg/m3 fell from 62% in 1998-2000 to 19% in 2010-2012. We found significant agreement between satellite-derived estimates and ground-based measurements outside North America and Europe (r = 0.81; n = 210; slope = 0.68). The low bias in satellite-derived estimates suggests that true global concentrations could be even greater. CONCLUSIONS: Satellite observations provide insight into global long-term changes in ambient PM2.5 concentrations. Satellite-derived estimates and ground-based PM2.5 observations from this study are available for public use.

(Elsevier Ltd.)The use of satellite-based aerosol optical depth (AOD) to est. fine particulate matter (PM2.5) for epidemiol. studies has increased substantially over the past few years. These recent studies often report moderate predictive power, which can generate downward bias in effect ests. In addn., AOD measurements have only moderate spatial resoln., and have substantial missing data. We make use of recent advances in MODIS satellite data processing algorithms Multi-Angle Implementation of Atm. Correction (MAIAC), which allow us to use 1 km (vs. currently available 10 km) resoln. AOD data. We developed and cross validated models to predict daily PM2.5 at a 1 × 1 km resoln. across the northeastern USA (New England, New York and New Jersey) for the years 2003-2011, allowing us to better differentiate daily and long term exposure between urban, suburban, and rural areas. Addnl., we developed an approach that allows us to generate daily high-resoln. 200 m localized predictions representing deviations from the area 1 × 1 km grid predictions. We used mixed models regressing PM2.5 measurements against day-specific random intercepts, and fixed and random AOD and temp. slopes. We then use generalized additive mixed models with spatial smoothing to generate grid cell predictions when AOD was missing. Finally, to get 200 m localized predictions, we regressed the residuals from the final model for each monitor against the local spatial and temporal variables at each monitoring site. Our model performance was excellent (mean out-of-sample R2 = 0.88). The spatial and temporal components of the out-of-sample results also presented very good fits to the withheld data (R2 = 0.87, R2 = 0.87). In addn., our results revealed very little bias in the predicted concns. (Slope of predictions vs. withheld observations = 0.99). Our daily model results show high predictive accuracy at high spatial resolns. and will be useful in reconstructing exposure histories for epidemiol. studies across this region.

(American Chemical Society)Estg. ground-level PM2.5 from satellite-derived aerosol optical depth (AOD) using a spatial statistical model is a promising new method to evaluate the spatial and temporal characteristics of PM2.5 exposure in a large geog. region. However, studies outside North America have been limited due to the lack of ground PM2.5 measurements to calibrate the model. Taking advantage of the newly established national monitoring network, we developed a national-scale geog. weighted regression (GWR) model to est. daily PM2.5 concns. in China with fused satellite AOD as the primary predictor. The results showed that the meteorol. and land use information can greatly improve model performance. The overall cross-validation (CV) R2 is 0.64 and root mean squared prediction error (RMSE) is 32.98 μg/m3. The mean prediction error (MPE) of the predicted annual PM2.5 is 8.28 μg/m3. Our predicted annual PM2.5 concns. indicated that over 96% of the Chinese population lives in areas that exceed the Chinese National Ambient Air Quality Std. (CNAAQS) Level 2 std. Our results also confirmed satellite-derived AOD in conjunction with meteorol. fields and land use information can be successfully applied to extend the ground PM2.5 monitoring network in China.

(American Association for the Advancement of Science)Many types of aerosols have lifetimes long enough for their transcontinental transport, making them potentially important contributors to air quality and climate change in remote locations. We est. that the mass of aerosols arriving at North American shores from overseas is comparable with the total mass of particulates emitted domestically. Curbing domestic emissions of particulates and precursor gases, therefore, is not sufficient to mitigate aerosol impacts in North America. The imported contribution is dominated by dust leaving Asia, not by combustion-generated particles. Thus, even a redn. of industrial emissions of the emerging economies of Asia could be overwhelmed by an increase of dust emissions due to changes in meteorol. conditions and potential desertification.

(Springer)Assessments of human health impacts assocd. with outdoor air pollution often use air quality models to represent exposure, but involve uncertainties due to coarse model resoln. Here, we quantify how ests. of mortality in the USA attributable to ozone (O3) and fine particulate matter (PM2.5) at coarse resoln. differ from those at finer resoln. Using the finest modeled concns. (12 km), we est. that 66,000 (95% CI, 39,300-84,500) all-cause and 21,400 (5,600-34,200) respiratory deaths per yr are attributable to PM2.5 and O3 concns. above low-concn. thresholds, resp. Using model results at 36 km resoln. gives mortality burdens that are 11 % higher for PM2.5 and 12% higher for O3 than the 12-km ests., suggesting a modest pos. bias. We also scale modeled concns. at 12 km to coarser resolns. by simple averaging and repeat the mortality assessment at multiple resolns. from 24 to 408 km, including the resolns. of global models; in doing so, we account for the effect of resoln. on population exposure. Coarse grid resolns. produce mortality ests. that are substantially biased low for PM2.5 (30-40 % lower than the 12-km est. at >250 km resoln.), but less than 6% higher for O3 at any resoln. Mortality ests. for primary PM2.5 species show greater bias at coarse resoln. than secondary species. These results suggest that coarse resoln. global models (>100 km) are likely biased low for PM2.5 health effects. For ozone, biases due to coarse resoln. may be much smaller, and the effect on modeled chem. likely dominates.

(National Academy of Sciences)Isoprene is a significant source of atm. org. aerosol; however, the oxidn. pathways that lead to secondary org. aerosol (SOA) have remained elusive. Here, we identify the role of two key reactive intermediates, epoxydiols of isoprene (IEPOX = β-IEPOX + δ-IEPOX) and methacryloylperoxynitrate (MPAN), which are formed during isoprene oxidn. under low- and high-NOx conditions, resp. Isoprene low-NOx SOA is enhanced in the presence of acidified sulfate seed aerosol (mass yield 28.6%) over that in the presence of neutral aerosol (mass yield 1.3%). Increased uptake of IEPOX by acid-catalyzed particle-phase reactions is shown to explain this enhancement. Under high-NOx conditions, isoprene SOA formation occurs through oxidn. of its second-generation product, MPAN. The similarity of the compn. of SOA formed from the photooxidn. of MPAN to that formed from isoprene and methacrolein demonstrates the role of MPAN in the formation of isoprene high-NOx SOA. Reactions of IEPOX and MPAN in the presence of anthropogenic pollutants (i.e., acidic aerosol produced from the oxidn. of SO2 and NO2, resp.) could be a substantial source of "missing urban SOA" not included in current atm. models.

(European Geosciences Union)Data from a recent field campaign in Mexico City are used to evaluate the performance of the EPA Federal Ref. Method for monitoring the ambient concns. of NO2. Measurements of NO2 from std. chemiluminescence monitors equipped with molybdenum oxide converters are compared with those from Tunable IR Laser Differential Absorption Spectroscopy (TILDAS) and Differential Optical Absorption Spectroscopy (DOAS) instruments. A significant interference in the chemiluminescence measurement is shown to account for up to 50% of ambient NO2 concn. during afternoon hours. As expected, this interference correlates well with non-NOx reactive nitrogen species (NOz) as well as with ambient O3 concns., indicating a photochem. source for the interfering species. A combination of ambient gas phase nitric acid and alkyl and multifunctional alkyl nitrates is deduced to be the primary cause of the interference. Observations at four locations at varying proximities to emission sources indicate that the percentage contribution of HNO3 to the interference decreases with time as the air parcel ages. Alkyl and multifunctional alkyl nitrate concns. are calcd. to reach concns. as high as several ppb inside the city, on par with the highest values previously obsd. in other urban locations. Averaged over the MCMA-2003 field campaign, the chemiluminescence monitor interference resulted in an av. measured NO2 concn. up to 22% greater than that from co-located spectroscopic measurements. Thus, this interference has the potential to initiate regulatory action in areas that are close to non-attainment and may mislead atm. photochem. models used to assess control strategies for photochem. oxidants.

(Massachusetts Medical Society)Although many studies have linked elevations in tropospheric ozone to adverse health outcomes, the effect of long-term exposure to ozone on air pollution-related mortality remains uncertain. The authors examd. the potential contribution of exposure to ozone to the risk of death from cardiopulmonary causes and specifically to death from respiratory causes. Data from the study cohort of the American Cancer Society Cancer Prevention Study II were correlated with air-pollution data from 96 metropolitan statistical areas in the United States. Data were analyzed from 448,850 subjects, with 118,777 deaths in an 18-yr follow-up period. Data on daily max. ozone concns. were obtained from Apr. 1 to Sept. 30 for the years 1977 through 2000. Data on concns. of fine particulate matter (particles that are ≤2.5 μm in aerodynamic diam. [PM2.5]) were obtained for the years 1999 and 2000. Assocns. between ozone concns. and the risk of death were evaluated with the use of std. and multilevel Cox regression models. In single-pollutant models, increased concns. of either PM2.5 or ozone were significantly assocd. with an increased risk of death from cardiopulmonary causes. In two-pollutant models, PM2.5 was assocd. with the risk of death from cardiovascular causes, whereas ozone was assocd. with the risk of death from respiratory causes. The estd. relative risk of death from respiratory causes that was assocd. with an increment in ozone concn. of 10 ppb was 1.040 (95% confidence interval, 1.010-1.067). The assocn. of ozone with the risk of death from respiratory causes was insensitive to adjustment for confounders and to the type of statistical model used. Thus, in this large study, the authors were not able to detect an effect of ozone on the risk of death from cardiovascular causes when the concn. of PM2.5 was taken into account. The authors did, however, demonstrate a significant increase in the risk of death from respiratory causes in assocn. with an increase in ozone concn.

(Elsevier Ltd.)Few studies on long-term exposure to air pollution and mortality have been reported from Europe. Within the multicenter European Study of Cohorts for Air Pollution Effects (ESCAPE), we aimed to investigate the assocn. between natural-cause mortality and long-term exposure to several air pollutants.We used data from 22 European cohort studies, which created a total study population of 367,251 participants. All cohorts were general population samples, although some were restricted to one sex only. With a strictly standardized protocol, we assessed residential exposure to air pollutants as annual av. concns. of particulate matter (PM) with diams. of less than 2.5 μm (PM2.5), less than 10 μm (PM10), and between 10 μm and 2.5 μm (PMcoarse), PM2.5 absorbance, and annual av. concns. of nitrogen oxides (NO2 and NOx), with land use regression models. We also investigated two traffic intensity variables-traffic intensity on the nearest road (vehicles per day) and total traffic load on all major roads within a 100 m buffer. We did cohort-specific statistical analyses using confounder models with increasing adjustment for confounder variables, and Cox proportional hazards models with a common protocol. We obtained pooled effect ests. through a random-effects meta-anal.The total study population consisted of 367,251 participants who contributed 5,118,039 person-years at risk (av. follow-up 13.9 years), of whom 29,076 died from a natural cause during follow-up. A significantly increased hazard ratio (HR) for PM2.5 of 1.07 (95% CI 1.02-1.13) per 5 μg/m3 was recorded. No heterogeneity was noted between individual cohort effect ests. (I2 p value=0.95). HRs for PM2·5 remained significantly raised even when we included only participants exposed to pollutant concns. lower than the European annual mean limit value of 25 μg/m3 (HR 1.06, 95% CI 1.00-1.12) or below 20 μg/m3 (1.07, 1.01-1.13).Long-term exposure to fine particulate air pollution was assocd. with natural-cause mortality, even within concn. ranges well below the present European annual mean limit value.

The chemical composition of particles varies across locations and time periods. Identifying the most harmful constituents and sources is an important health and regulatory concern. OBJECTIVES: We examined pollutant sources for associations with risk of hospital admissions for cardiovascular and respiratory causes. METHODS: We obtained PM2.5 filter samples for four counties in Connecticut and Massachusetts and analyzed them for PM2.5 elements. Source apportionment was used to estimate daily PM2.5 contributions from sources (traffic, road dust, oil combustion, and sea salt as well as a regional source representing coal combustion and other sources). Associations between daily PM2.5 constituents and sources and risk of cardiovascular and respiratory hospitalizations for the Medicare population (> 333,000 persons ≥ 65 years of age) were estimated with time-series analyses (August 2000-February 2004). RESULTS: PM2.5 total mass and PM2.5 road dust contribution were associated with cardiovascular hospitalizations, as were the PM2.5 constituents calcium, black carbon, vanadium, and zinc. For respiratory hospitalizations, associations were observed with PM2.5 road dust, and sea salt as well as aluminum, calcium, chlorine, black carbon, nickel, silicon, titanium, and vanadium. Effect estimates were generally robust to adjustment by co-pollutants of other constituents. An interquartile range increase in same-day PM2.5 road dust (1.71 μg/m3) was associated with a 2.11% (95% CI: 1.09, 3.15%) and 3.47% (95% CI: 2.03, 4.94%) increase in cardiovascular and respiratory admissions, respectively. CONCLUSIONS: Our results suggest some particle sources and constituents are more harmful than others and that in this Connecticut/Massachusetts region the most harmful particles include black carbon, calcium, and road dust PM2.5.

(National Academy of Sciences)Air pollution in China and other parts of Asia poses large health risks and is an important contributor to global climate change. Almost half of Chinese homes use biomass and coal fuels for cooking and heating. China's economic growth and infrastructure development has led to increased emissions from coal-fired power plants and an expanding fleet of motor vehicles. Black carbon (BC) from incomplete biomass and fossil fuel combustion is the most strongly light-absorbing component of particulate matter (PM) air pollution and the second most important climate-forcing human emission. PM compn. and sources may also be related to its human health impact. We enrolled 280 women living in a rural area of northwestern Yunnan where biomass fuels are commonly used. We measured their blood pressure, distance from major traffic routes, and daily exposure to BC (pyrolytic biomass combustion), water-sol. org. aerosol (org. aerosol from biomass combustion), and, in a subset, hopane markers (motor vehicle emissions) in winter and summer. BC had the strongest assocn. with systolic blood pressure (SBP) (4.3 mm Hg; P < 0.001), followed by PM mass and water-sol. org. mass. The effect of BC on SBP was almost three times greater in women living near the highway [6.2 mm Hg ; 95% confidence interval (CI), 3.6 to 8.9 vs. 2.6 mm Hg ; 95% CI, 0.1 to 5.2]. Our findings suggest that BC from combustion emissions is more strongly assocd. with blood pressure than PM mass, and that BC's health effects may be larger among women living near a highway and with greater exposure to motor vehicle emissions.

(2015), 26 (3), 321-7 ISSN:.BACKGROUND: Fine particulate (PM2.5) air pollution has been consistently linked to survival, but reported effect estimates are geographically heterogeneous. Exposure to different types of particle mixtures may explain some of this variation. METHODS: We used k-means cluster analyses to identify cities with similar pollution profiles, (ie, PM2.5 composition) across the United States. We examined the impact of PM2.5 on survival, and its variation across clusters of cities with similar PM2.5 composition, among Medicare enrollees in 81 US cities (2000-2010). We used time-varying annual PM2.5 averages, measured at ambient central monitoring sites, as the exposure of interest. We ran by-city Cox models, adjusting for individual data on previous cardiopulmonary-related hospitalizations and stratifying by follow-up time, age, gender, and race. This eliminates confounding by factors varying across cities and long-term trends, focusing on year-to-year variations of air pollution around its city-specific mean and trend. We then pooled the city-specific effects using a random effects meta-regression. In this second stage, we also assessed effect modification by cluster membership and estimated cluster-specific PM2.5 effects. RESULTS: We followed more than 19 million subjects and observed more than 6 million deaths. We found a harmful impact of annual PM2.5 concentrations on survival (hazard ratio = 1.11 [95% confidence interval = 1.01, 1.23] per 10 μg/m). This effect was modified by particulate composition, with higher effects observed in clusters containing high concentrations of nickel, vanadium, and sulfate. For instance, our highest effect estimate was observed in cities with harbors in the Northwest, characterized by high nickel, vanadium, and elemental carbon concentrations (1.9 [1.1, 3.3]). We observed null or negative associations in clusters with high oceanic and crustal particles. CONCLUSIONS: To the best of our knowledge, this is the first study to examine the association between PM2.5 composition and survival. Our findings indicate that long-term exposure to fuel oil combustion and power plant emissions have the highest impact on survival.

We investigated short-term changes in ambient air pollutant concentrations, including speciated particulate matter less than 2.5 μm in diameter (PM2.5), in relation to emergency department (ED) visits for respiratory infections in young children. Daily counts of ED visits for bronchitis and bronchiolitis (n = 80,399), pneumonia (n = 63,359), and upper respiratory infection (URI) (n = 359,246) among children 0-4 years of age were collected from hospitals in the Atlanta, Georgia, area for the period 1993-2010. Daily pollutant measurements were combined across monitoring stations using population weighting. In Poisson generalized linear models, 3-day moving average concentrations of ozone, nitrogen dioxide, and the organic carbon fraction of particulate matter less than 2.5 μm in diameter (PM2.5) were associated with ED visits for pneumonia and URI. Ozone associations were strongest and were observed at low (cold-season) concentrations; a 1-interquartile range increase predicted a 4% increase (95% confidence interval: 2%, 6%) in visits for URI and an 8% increase (95% confidence interval: 4%, 13%) in visits for pneumonia. Rate ratios tended to be higher in the 1- to 4-year age group compared with infants. Results suggest that primary traffic pollutants, ozone, and the organic carbon fraction of PM2.5 exacerbate upper and lower respiratory infections in early life, and that the carbon fraction of PM2.5 is a particularly harmful component of the ambient particulate matter mixture.

Because much ambient PM is derived from combustion sources, we tested the hypothesis that the health effects of PM arise from anthropogenic PM that contains bioavailable transition metals. The PM samples studied derived from three emission sources (two oil and one coal fly ash) and four ambient airsheds (St. Louis, MO; Washington; Dusseldorf, Germany; and Ottawa, Canada). PM was administered to rats by intratracheal instillation in equimass or equimetal doses to address directly the influence of PM mass versus metal content on acute lung injury and inflammation. Our results indicated that the lung dose of bioavailable transition metal, not instilled PM mass, was the primary determinant of the acute inflammatory response for both the combustion source and ambient PM samples. Residual oil fly ash, a combustion PM rich in bioavailable metal, was evaluated in a rat model of cardiopulmonary disease (pulmonary vasculitis/hypertension) to ascertain whether the disease state augmented sensitivity to that PM. Significant mortality and enhanced airway responsiveness were observed. Analysis of the lavaged lung fluids suggested that the milieu of the inflamed lung amplified metal-mediated oxidant chemistry to jeopardize the compromised cardiopulmonary system. We propose that soluble metals from PM mediate the array of PM-associated injuries to the cardiopulmonary system of the healthy and at-risk compromised host.

(U. S. Department of Health and Human Services, Public Health Services)Dozens of studies link acute exposure to particulate matter (PM) air pollution with premature mortality and morbidity, but questions remain about which species and sources in the vast PM mixt. are responsible for the obsd. health effects. Although a few studies exist on the effects of species and sources in U.S. cities, European cities-which have a higher proportion of diesel engines and denser urban populations-have not been well characterized. Information on the effects of specific sources could aid in targeting pollution control and in articulating the biol. mechanisms of PM. Our study examd. the effects of various PM sources on daily mortality for 2003 through 2007 in Barcelona, a densely populated city in the northeast corner of Spain. Source apportionment for PM ≤ 2.5 μm and ≤ 10 μm in aerodynamic diam. (PM2.5 and PM10) using pos. matrix factorization identified eight different factors. Case-crossover regression anal. was used to est. the effects of each factor. Several sources of PM2.5, including vehicle exhaust, fuel oil combustion, secondary nitrate/orgs., minerals, secondary sulfate/orgs., and road dust, had statistically significant assocns. (p < 0.05) with all-cause and cardiovascular mortality. Also, in some cases relative risks for a resp. interquartile range increase in concn. were higher for specific sources than for total PM2.5 mass. These results along with those from our multisource models suggest that traffic, sulfate from shipping and long-range transport, and construction dust are important contributors to the adverse health effects linked to PM.

It has been suggested that particles from combustion sources are more relevant to human health than are particles from other sources, but the impact of policies directed at reducing PM from combustion processes is usually relatively small when effects are estd. for a redn. in the total mass concn. We evaluated the value of black carbon particles (BCP) as an addnl. indicator in air quality management. We performed a systematic review and meta-anal. of health effects of BCP compared with PM mass based on data from time-series studies and cohort studies that measured both exposures. We compared the potential health benefits of a hypothetical traffic abatement measure, using near-roadway concn. increments of BCP and PM2.5 based on data from prior studies. Estd. health effects of a 1-μg/m3 increase in exposure were greater for BCP than for PM10 or PM2.5, but estd. effects of an interquartile range increase were similar. Two-pollutant models in time-series studies suggested that the effect of BCP was more robust than the effect of PM mass. The estd. increase in life expectancy assocd. with a hypothetical traffic abatement measure was four to nine times higher when expressed in BCP compared with an equiv. change in PM2.5 mass. BCP is a valuable addnl. air quality indicator to evaluate the health risks of air quality dominated by primary combustion particles.

(BioMed Central Ltd.)Background: The involvement of particulate matter (PM) in cardiorespiratory diseases is now established in developed countries whereas in developing areas such as Africa with a high level of specific pollution, PM pollution and its effects are poorly studied. Our objective was to characterize the biol. reactivity of urban African aerosols on human bronchial epithelial cells in relation to PM physico-chem. properties to identify toxic sources. Methods: Size-speciated aerosol chem. compn. was analyzed in Bamako (BK, Mali, 2 samples with one having desert dust event BK1) and Dakar (DK; Senegal) for Ultrafine UF, Fine F and Coarse C PM. PM reactivity was studied in human bronchial epithelial cells investigating six biomarkers (oxidative stress responsive genes and proinflammatory cytokines). Results: PM mass concns. were mainly distributed in coarse mode (60%) and were impressive in BK1 due to the desert dust event. BK2 and DK samples showed a high content of total carbon characteristic of urban areas. The DK sample had huge PAH quantities in bulk aerosol compared with BK that had more water sol. org. carbon and metals. Whatever the site, UF and F PM triggered the mRNA expression of the different biomarkers whereas coarse PM had little or no effect. The GM-CSF biomarker was the most discriminating and showed the strongest pro-inflammatory effect of BK2 PM. The anal. of gene expression signature and of their correlation with main PM compds. revealed that PM-induced responses are mainly related to org. compds. The toxicity of African aerosols is carried by the finest PM as with Parisian aerosols, but when considering PM mass concns., the African population is more highly exposed to toxic particulate pollution than French population. Regarding the prevailing sources in each site, aerosol biol. impacts are higher for incomplete combustion sources resulting from two-wheel vehicles and domestic fires than from diesel vehicles (Dakar). Desert dust events seem to produce fewer biol. impacts than anthropogenic sources. Discussion: Our study shows that combustion sources contribute to the high toxicity of F and UF PM of African urban aerosols, and underlines the importance of emission mitigation and the imperative need to evaluate and to regulate particulate pollution in Africa.

(Elsevier Ltd.)A review. It has been hypothesized that the compn. of particulate matter (PM) may be a better predictor of health effects than PM mass alone. The regional differences in PM compn. and the heterogeneity in PM risk ests. in large multi-city epidemiol. studies are consistent with this hypothesis. Since 2005, efforts have been made to relate apportioned components and sources of PM with human health outcomes in epidemiol., controlled human exposure and toxicol. studies. We reviewed published studies that: (1) focused on short-term exposure to PM; (2) included at least five components of PM; (3) grouped them into factors or sources; and (4) used quant. methods to examine the relationship between the factors or sources and health effects. Examn. includes to det. if specific groups of PM components or sources of PM are consistently linked to specific health effects across studies. The studies suggest that cardiovascular effects may be assocd. with PM2.5 from crustal or combustion sources, including traffic, but at this time, no consistent relationships have emerged. Fewer studies evaluated respiratory health effects, and the evidence for assocns. was limited. Apportionment methods have linked a variety of health effects to multiple groups of PM components and sources of PM, but the collective evidence has not yet isolated factors or sources that would be closely and unequivocally related to specific health outcomes.

Several studies have analyzed the ancillary impacts of GHG policies for a variety of locations, pollutants, and policies. In this paper we review the existing evidence on ancillary health benefits relating to air pollution from various GHG strategies and provide a framework for such analysis. METHODS: We evaluate techniques used in different stages of such research for estimation of: (1) changes in air pollutant concentrations; (2) avoided adverse health endpoints; and (3) economic valuation of health consequences. The limitations and merits of various methods are examined. Finally, we conclude with recommendations for ancillary benefits analysis and related research gaps in the relevant disciplines. RESULTS: We found that to date most assessments have focused their analysis more heavily on one aspect of the framework (e.g., economic analysis). While a wide range of methods was applied to various policies and regions, results from multiple studies provide strong evidence that the short-term public health and economic benefits of ancillary benefits related to GHG mitigation strategies are substantial. Further, results of these analyses are likely to be underestimates because there are a number of important unquantified health and economic endpoints. CONCLUSION: Remaining challenges include integrating the understanding of the relative toxicity of particulate matter by components or sources, developing better estimates of public health and environmental impacts on selected sub-populations, and devising new methods for evaluating heretofore unquantified and non-monetized benefits.

Here we simulate the co-benefits of global GHG redns. on air quality and human health using a global atm. model and consistent future scenarios, via two mechanisms: reducing co-emitted air pollutants, and slowing climate change and its effect on air quality. We use new relationships between chronic mortality and exposure to fine particulate matter and ozone, global modeling methods and new future scenarios. Relative to a ref. scenario, global GHG mitigation avoids 0.5±0.2, 1.3±0.5 and 2.2±0.8 million premature deaths in 2030, 2050 and 2100. Global av. marginal co-benefits of avoided mortality are US$50-380 per tonne of CO2, which exceed previous ests., exceed marginal abatement costs in 2030 and 2050, and are within the low range of costs in 2100. East Asian co-benefits are 10-70 times the marginal cost in 2030. Air quality and health co-benefits, esp. as they are mainly local and near-term, provide strong addnl. motivation for transitioning to a low-carbon future.

(American Association for the Advancement of Science)Tropospheric ozone and black carbon (BC) contribute to both degraded air quality and global warming. We considered ~400 emission control measures to reduce these pollutants by using current technol. and experience. We identified 14 measures targeting methane and BC emissions that reduce projected global mean warming ~0.5°C by 2050. This strategy avoids 0.7 to 4.7 million annual premature deaths from outdoor air pollution and increases annual crop yields by 30 to 135 million metric tons due to ozone redns. in 2030 and beyond. Benefits of methane emissions redns. are valued at 700 to 5000 per metric ton, which is well above typical marginal abatement costs (less than 250). The selected controls target different sources and influence climate on shorter time scales than those of carbon dioxide-redn. measures. Implementing both substantially reduces the risks of crossing the 2°C threshold.

(American Chemical Society)The implicit assumption that biogenic secondary org. aerosol (SOA) is natural and cannot be controlled hinders effective air quality management. Anthropogenic pollution facilitates transformation of naturally-emitted volatile org. compds. (VOC) to the particle phase, enhancing ambient biogenic SOA concns. Thus, it is conceivable a portion of ambient biogenic SOA can be removed by controlling anthropogenic pollutant emissions. Direct measurement of the controllable fraction of biogenic SOA is not possible, but can be estd. using 3-dimensional photochem. air quality modeling. To examine this, 22 Community Multi-scale Air Quality model simulations were conducted over the continental US. Relative contributions of 5 emitted pollution classes (NOx, NH3, SOx, reactive non-methane C, primary carbonaceous particulate matter) on biogenic SOA were estd. by removing anthropogenic emissions of these pollutants, one at a time then all together. Model results demonstrated a strong effect of anthropogenic emissions on predicted biogenic SOA concns., suggesting >50% of biogenic SOA in the eastern US can be controlled. Since biogenic SOA is substantially enhanced by controllable emissions, classifying SOA as biogenic or anthropogenic based solely on VOC origin is not sufficient to describe the controllable fraction.

(Copernicus Publications)The literature on atm. particulate matter (PM), or atm. aerosol, has increased enormously over the last 2 decades and amts. now to some 1500-2000 papers per yr in the refereed literature. This is in part due to the enormous advances in measurement technologies, which have allowed for an increasingly accurate understanding of the chem. compn. and of the phys. properties of atm. particles and of their processes in the atm. The growing scientific interest in atm. aerosol particles is due to their high importance for environmental policy. In fact, particulate matter constitutes one of the most challenging problems both for air quality and for climate change policies. In this context, this paper reviews the most recent results within the atm. aerosol sciences and the policy needs, which have driven much of the increase in monitoring and mechanistic research over the last 2 decades. The synthesis reveals many new processes and developments in the science underpinning climate-aerosol interactions and effects of PM on human health and the environment. However, while airborne particulate matter is responsible for globally important influences on premature human mortality, we still do not know the relative importance of the different chem. components of PM for these effects. Likewise, the magnitude of the overall effects of PM on climate remains highly uncertain. Despite the uncertainty there are many things that could be done to mitigate local and global problems of atm. PM. Recent analyses have shown that reducing black carbon (BC) emissions, using known control measures, would reduce global warming and delay the time when anthropogenic effects on global temp. would exceed 2 °C. Likewise, cost-effective control measures on ammonia, an important agricultural precursor gas for secondary inorg. aerosols (SIA), would reduce regional eutrophication and PM concns. in large areas of Europe, China and the USA. Thus, there is much that could be done to reduce the effects of atm. PM on the climate and the health of the environment and the human population. A prioritized list of actions to mitigate the full range of effects of PM is currently undeliverable due to shortcomings in the knowledge of aerosol science; among the shortcomings, the roles of PM in global climate and the relative roles of different PM precursor sources and their response to climate and land use change over the remaining decades of this century are prominent. In any case, the evidence from this paper strongly advocates for an integrated approach to air quality and climate policies.

(U. S. Department of Health and Human Services, National Institutes of Health)Background: Assocns. between airborne particles and health outcomes have been documented worldwide; however, there is limited information regarding health effects assocd. with different particle sizes. Objectives: We explored the assocn. between size-fractionated particle no. concns. (PNCs) and daily mortality in Shenyang, China. Methods: We collected daily data on cause-specific mortality and PNCs for particles measuring 0.25-10 μm in diam. between 1 Dec. 2006 and 30 Nov. 2008. We used Quasi-Poisson regression generalized additive models to est. assocns. between PNCs and mortality, and we used natural spline smoothing functions to adjust for time-varying covariates and long-term and seasonal trends. Results: Mean nos. of daily deaths were 67, 32 and 7 for all natural causes, cardiovascular diseases, and respiratory diseases, resp. Interquartile range (IQR) increases in PNCs for particles measuring 0.25-0.50 μm were significantly assocd. with total and cardiovascular mortality, but not respiratory mortality. Effect ests. were larger for PNCs during the warm season than the cool season, and increased with decreasing particle size. IQR increases in PNCs of 0.25-0.28 μm, 0.35-0.40 μm, and 0.45-0.50 μm particles were assocd. with 2.41% (95% CI: 1.23, 3.58 %), 1.31% (95% CI: 0.52, 2.09 %), and 0.45% (95% CI: 0.04, 0.87 %) higher total mortality, resp. Assocns. were generally stable after adjustment for mass concns. of ambient particles and gaseous pollutants. Conclusions: Our findings suggest that particles <0.5 μm in diam. may be most responsible for adverse health effects of particulate air pollution and that adverse health effects may increase with decreasing particle size.

(Elsevier)Air quality modeling could potentially improve exposure ests. for use in epidemiol. studies. We investigated this application of air quality modeling by estg. location-specific (point) and spatially-aggregated (county level) exposure concns. of particulate matter with an aerodynamic diam. less than or equal to 2.5 μm (PM2.5) and ozone (O3) for the eastern U.S. in 2002 using the community multi-scale air quality (CMAQ) modeling system and a traditional approach using ambient monitors. The monitoring approach produced ests. for 370 and 454 counties for PM2.5 and O3, resp. Modeled ests. included 1861 counties, covering 50% more population. The population uncovered by monitors differed from those near monitors (e.g., urbanicity, race, education, age, unemployment, income, modeled pollutant levels). CMAQ overestimated O3 (annual normalized mean bias=4.30%), while modeled PM2.5 had an annual normalized mean bias of -2.09%, although bias varied seasonally, from 32% in Nov. to -27% in July. Epidemiol. may benefit from air quality modeling, with improved spatial and temporal resoln. and the ability to study populations far from monitors that may differ from those near monitors. However, model performance varied by measure of performance, season, and location. Thus, the appropriateness of using such modeled exposures in health studies depends on the pollutant and metric of concern, acceptable level of uncertainty, population of interest, study design, and other factors.

(2013), 24 (4), 555-61 ISSN:.BACKGROUND: Many studies have reported associations between ambient particulate matter (PM) and adverse health effects, focused on either short-term (acute) or long-term (chronic) PM exposures. For chronic effects, the studied cohorts have rarely been representative of the population. We present a novel exposure model combining satellite aerosol optical depth and land-use data to investigate both the long- and short-term effects of PM2.5 exposures on population mortality in Massachusetts, United States, for the years 2000-2008. METHODS: All deaths were geocoded. We performed two separate analyses: a time-series analysis (for short-term exposure) where counts in each geographic grid cell were regressed against cell-specific short-term PM2.5 exposure, temperature, socioeconomic data, lung cancer rates (as a surrogate for smoking), and a spline of time (to control for season and trends). In addition, for long-term exposure, we performed a relative incidence analysis using two long-term exposure metrics: regional 10 × 10 km PM2.5 predictions and local deviations from the cell average based on land use within 50 m of the residence. We tested whether these predicted the proportion of deaths from PM-related causes (cardiovascular and respiratory diseases). RESULTS: For short-term exposure, we found that for every 10-μg/m increase in PM 2.5 exposure there was a 2.8% increase in PM-related mortality (95% confidence interval [CI] = 2.0-3.5). For the long-term exposure at the grid cell level, we found an odds ratio (OR) for every 10-μg/m increase in long-term PM2.5 exposure of 1.6 (CI = 1.5-1.8) for particle-related diseases. Local PM2.5 had an OR of 1.4 (CI = 1.3-1.5), which was independent of and additive to the grid cell effect. CONCLUSIONS: We have developed a novel PM2.5 exposure model based on remote sensing data to assess both short- and long-term human exposures. Our approach allows us to gain spatial resolution in acute effects and an assessment of long-term effects in the entire population rather than a selective sample from urban locations.

(2005), 16 (6), 727-36 ISSN:1044-3983.BACKGROUND: The assessment of air pollution exposure using only community average concentrations may lead to measurement error that lowers estimates of the health burden attributable to poor air quality. To test this hypothesis, we modeled the association between air pollution and mortality using small-area exposure measures in Los Angeles, California. METHODS: Data on 22,905 subjects were extracted from the American Cancer Society cohort for the period 1982-2000 (5,856 deaths). Pollution exposures were interpolated from 23 fine particle (PM2.5) and 42 ozone (O3) fixed-site monitors. Proximity to expressways was tested as a measure of traffic pollution. We assessed associations in standard and spatial multilevel Cox regression models. RESULTS: After controlling for 44 individual covariates, all-cause mortality had a relative risk (RR) of 1.17 (95% confidence interval=1.05-1.30) for an increase of 10 mug/m PM2.5 and a RR of 1.11 (0.99-1.25) with maximal control for both individual and contextual confounders. The RRs for mortality resulting from ischemic heart disease and lung cancer deaths were elevated, in the range of 1.24-1.6, depending on the model used. These PM results were robust to adjustments for O3 and expressway exposure. CONCLUSION: Our results suggest the chronic health effects associated with within-city gradients in exposure to PM2.5 may be even larger than previously reported across metropolitan areas. We observed effects nearly 3 times greater than in models relying on comparisons between communities. We also found specificity in cause of death, with PM2.5 associated more strongly with ischemic heart disease than with cardiopulmonary or all-cause mortality.

(U. S. Department of Health and Human Services, National Institutes of Health)BACKGROUND: Approx. 2.8 billion people cook with solid fuels. Research has focused on the health impacts of indoor exposure to fine particulate pollution. Here, for the 2010 Global Burden of Disease project (GBD 2010), we evaluated the impact of household cooking with solid fuels on regional population-weighted ambient PM2.5 (particulate matter ≤ 2.5 μm) pollution (APM2.5). OBJECTIVES: We estd. the proportion and concns. of APM2.5 attributable to household cooking with solid fuels (PM2.5-cook) for the years 1990, 2005, and 2010 in 170 countries, and assocd. ill health. METHODS: We used an energy supply-driven emissions model (GAINS; Greenhouse Gas and Air Pollution Interactions and Synergies) and source-receptor model (TM5-FASST) to est. the proportion of APM2.5 produced by households and the proportion of household PM2.5 emissions from cooking with solid fuels. We estd. health effects using GBD 2010 data on ill health from APM2.5 exposure. RESULTS: In 2010, household cooking with solid fuels accounted for 12% of APM2.5 globally, varying from 0% of APM2.5 in five higher-income regions to 37% (2.8 μg/m3 of 6.9 μg/m3 total) in southern sub-Saharan Africa. PM2.5-cook constituted > 10% of APM2.5 in seven regions housing 4.4 billion people. South Asia showed the highest regional concn. of APM2.5 from household cooking (8.6 μg/m3). On the basis of GBD 2010, we est. that exposure to APM2.5 from cooking with solid fuels caused the loss of 370,000 lives and 9.9 million disability-adjusted life years globally in 2010. CONCLUSIONS: PM2.5 emissions from household cooking constitute an important portion of APM3.5 concns. in many places, including India and China. Efforts to improve ambient air quality will be hindered if household cooking conditions are not addressed.

(Nature Publishing Group)Assessing the global burden of disease is based on epidemiol. cohort studies which connect premature mortality to a wide range of causes, including long-term health impacts of O3 and fine particulate matter (PM2.5). It is difficult to quantify premature mortality related to air pollution, notably in regions where air quality is not monitored, and because toxicity of particles from various sources may vary. This work used a global atm. chem. model to assess the link between premature mortality and 7 emission source categories in urban and rural environments. In accord with the global burden of disease for 2010 (S.S. Lim, et al., 2013), the authors calcd. outdoor air pollution, mostly PM2.5, led to 3.3 million (95% confidence interval, 1.61-4.81) premature deaths/yr worldwide, predominantly in Asia. It was primarily assumed that all particles were equally toxic, but a sensitivity study was conducted to account for differential toxicity. Results showed emissions from residential energy use (heating, cooking), prevalent in India and China, had the largest effect on premature mortality globally, even more dominant if carbonaceous particles are assumed to be most toxic. In much of the US and several other countries, traffic and power generation emissions are important. In eastern US, Europe, Russia, and East Asia, agricultural emissions provide the largest relative contribution to PM2.5, with estd. overall health impact dependent on particle toxicity assumptions. Model projections based on a business-as-usual emission scenario indicated the contribution of outdoor air pollution to premature mortality could double by 2050.

(Lippincott Williams & Wilkins)A review. In 2004, the first American Heart Assocn. scientific statement on "Air Pollution and Cardiovascular Disease" concluded that exposure to particulate matter (PM) air pollution contributes to cardiovascular morbidity and mortality. In the interim, numerous studies have expanded our understanding of this assocn. and further elucidated the physiol. and mol. mechanisms involved. The main objective of this updated American Heart Assocn. scientific statement is to provide a comprehensive review of the new evidence linking PM exposure with cardiovascular disease, with a specific focus on highlighting the clin. implications for researchers and healthcare providers. The writing group also sought to provide expert consensus opinions on many aspects of the current state of science and updated suggestions for areas of future research. On the basis of the findings of this review, several new conclusions were reached, including the following: Exposure to PM < 2.5 μm in diam. (PM2.5) over a few hours to weeks can trigger cardiovascular disease-related mortality and nonfatal events; longer-term exposure (eg, a few years) increases the risk for cardiovascular mortality to an even greater extent than exposures over a few days and reduces life expectancy within more highly exposed segments of the population by several months to a few years; redns. in PM levels are assocd. with decreases in cardiovascular mortality within a time frame as short as a few years; and many credible pathol. mechanisms have been elucidated that lend biol. plausibility to these findings. It is the opinion of the writing group that the overall evidence is consistent with a causal relationship between PM2.5 exposure and cardiovascular morbidity and mortality. This body of evidence has grown and been strengthened substantially since the first American Heart Assocn. scientific statement was published. Finally, PM2.5 exposure is deemed a modifiable factor that contributes to cardiovascular morbidity and mortality.

However, adequate direct evidence to identify the shape of the mortality RR functions at the high ambient concentrations observed in many places in the world is lacking. OBJECTIVE: We developed RR functions over the entire global exposure range for causes of mortality in adults: ischemic heart disease (IHD), cerebrovascular disease (stroke), chronic obstructive pulmonary disease (COPD), and lung cancer (LC). We also developed RR functions for the incidence of acute lower respiratory infection (ALRI) that can be used to estimate mortality and lost-years of healthy life in children < 5 years of age. METHODS: We fit an integrated exposure-response (IER) model by integrating available RR information from studies of ambient air pollution (AAP), second hand tobacco smoke, household solid cooking fuel, and active smoking (AS). AS exposures were converted to estimated annual PM2.5 exposure equivalents using inhaled doses of particle mass. We derived population attributable fractions (PAFs) for every country based on estimated worldwide ambient PM2.5 concentrations. RESULTS: The IER model was a superior predictor of RR compared with seven other forms previously used in burden assessments. The percent PAF attributable to AAP exposure varied among countries from 2 to 41 for IHD, 1 to 43 for stroke, < 1 to 21 for COPD, < 1 to 25 for LC, and < 1 to 38 for ALRI. CONCLUSIONS: We developed a fine particulate mass-based RR model that covered the global range of exposure by integrating RR information from different combustion types that generate emissions of particulate matter. The model can be updated as new RR information becomes available.

Risk factor quantification, particularly of modifiable risk factors, can help to identify emerging threats to population health and opportunities for prevention. The GBD 2013 provides a timely opportunity to update the comparative risk assessment with new data for exposure, relative risks, and evidence on the appropriate counterfactual risk distribution. METHODS: Attributable deaths, years of life lost, years lived with disability, and disability-adjusted life-years (DALYs) have been estimated for 79 risks or clusters of risks using the GBD 2010 methods. Risk-outcome pairs meeting explicit evidence criteria were assessed for 188 countries for the period 1990-2013 by age and sex using three inputs: risk exposure, relative risks, and the theoretical minimum risk exposure level (TMREL). Risks are organised into a hierarchy with blocks of behavioural, environmental and occupational, and metabolic risks at the first level of the hierarchy. The next level in the hierarchy includes nine clusters of related risks and two individual risks, with more detail provided at levels 3 and 4 of the hierarchy. Compared with GBD 2010, six new risk factors have been added: handwashing practices, occupational exposure to trichloroethylene, childhood wasting, childhood stunting, unsafe sex, and low glomerular filtration rate. For most risks, data for exposure were synthesised with a Bayesian meta-regression method, DisMod-MR 2.0, or spatial-temporal Gaussian process regression. Relative risks were based on meta-regressions of published cohort and intervention studies. Attributable burden for clusters of risks and all risks combined took into account evidence on the mediation of some risks such as high body-mass index (BMI) through other risks such as high systolic blood pressure and high cholesterol. FINDINGS: All risks combined account for 57·2% (95% uncertainty interval [UI] 55·8-58·5) of deaths and 41·6% (40·1-43·0) of DALYs. Risks quantified account for 87·9% (86·5-89·3) of cardiovascular disease DALYs, ranging to a low of 0% for neonatal disorders and neglected tropical diseases and malaria. In terms of global DALYs in 2013, six risks or clusters of risks each caused more than 5% of DALYs: dietary risks accounting for 11·3 million deaths and 241·4 million DALYs, high systolic blood pressure for 10·4 million deaths and 208·1 million DALYs, child and maternal malnutrition for 1·7 million deaths and 176·9 million DALYs, tobacco smoke for 6·1 million deaths and 143·5 million DALYs, air pollution for 5·5 million deaths and 141·5 million DALYs, and high BMI for 4·4 million deaths and 134·0 million DALYs. Risk factor patterns vary across regions and countries and with time. In sub-Saharan Africa, the leading risk factors are child and maternal malnutrition, unsafe sex, and unsafe water, sanitation, and handwashing. In women, in nearly all countries in the Americas, north Africa, and the Middle East, and in many other high-income countries, high BMI is the leading risk factor, with high systolic blood pressure as the leading risk in most of Central and Eastern Europe and south and east Asia. For men, high systolic blood pressure or tobacco use are the leading risks in nearly all high-income countries, in north Africa and the Middle East, Europe, and Asia. For men and women, unsafe sex is the leading risk in a corridor from Kenya to South Africa. INTERPRETATION: Behavioural, environmental and occupational, and metabolic risks can explain half of global mortality and more than one-third of global DALYs providing many opportunities for prevention. Of the larger risks, the attributable burden of high BMI has increased in the past 23 years. In view of the prominence of behavioural risk factors, behavioural and social science research on interventions for these risks should be strengthened. Many prevention and primary care policy options are available now to act on key risks. FUNDING: Bill & Melinda Gates Foundation.

(American Chemical Society)Ambient air pollution exposure is a major risk factor for global disease. Assessing the impact of air pollution on population health and evaluating trends relative to other major risk factors requires regularly updated, accurate, spatially resolved exposure ests. This work combined satellite-based ests., chem. transport model simulations, and ground measurements from 79 countries to produce global ests. of annual av. fine particle (PM2.5) and O3 concns. at 0.1° × 0.1° spatial resoln. for 5-yr intervals from 1990 to 2010 and year 2013. These ests. were used to assess population-weighted mean concns. for 1990-2013 for 188 countries. In 2013, 87% of the world population lived in areas exceeding the World Health Organization air quality guideline (10 μg/m3 PM2.5 annual av.). From 1990 to 2013, global population-weighted PM2.5 increased 20.4%, driven by trends in southern and southeastern Asia and China. Decreases in population-weighted mean PM2.5 concns. were evident in most high income countries. Population-weighted mean O3 concns. increased globally 8.9% from 1990 to 2013, with increases in most countries; modest decreases occurred in North America, parts of Europe, and several southeastern Asia countries.

(American Chemical Society)Ambient fine particulate matter (PM2.5) has a large, well-documented global burden of disease. This work used high-resoln. (10 km, global-coverage) concn. data and cause-specific integrated exposure-response functions developed for the Global Burden of Disease 2010 to assess how regional and global improvements in ambient air quality could reduce attributable mortality from PM2.5. Overall, an aggressive global program of PM2.5 mitigation in accord with World Health Organization interim guidelines could avoid 750,000 (23%) of the 3.2 million deaths/yr currently (2010) attributable to ambient PM2.5. Modest improvements in PM2.5 in relatively clean regions (North America, Europe) would result in surprisingly large avoided mortality, due to demog. factors and the non-linear concn.-response relationship which describes the risk of PM in relation to several important causes of death. Major air quality improvements would be required to substantially reduce mortality from PM2.5 in more polluted regions, e.g., China and India. Forecasted demog. and epidemiol. transitions in India and China imply that to maintain PM2.5-attributable mortality rates (deaths/100,000 people-yr) const., av. PM2.5 concns. would need to decline by ∼20-30% over the next 15 years to merely offset increases in PM2.5-attributable mortality from aging populations. An effective program to deliver clean air to the most polluted regions could avoid several hundred thousand premature deaths each year.

(Air & Waste Management Association)A review. In celebration of the 100th anniversary of the Air & Waste Management Assocn., this review examines the history of air quality management (AQM) in the United States over the last century, with an emphasis on the ambient stds. programs established by the landmark 1970 Clean Air Act (CAA) Amendments. The current CAA system is a hybrid of several distinct air pollution control philosophies, including the recursive or circular system driven by ambient stds. Although this evolving system has resulted in tremendous improvements in air quality, it has been far from perfect in terms of timeliness and effectiveness. The paper looks at several periods in the history of the U.S. program, including:. (1) 1900-1970, Spanning the early smoke abatement and smog control programs, the first federal involvement, and the development of a hybrid AQM approach in the 1970 CAA;. (2) 1971-1976, When the first National Ambient Air Quality Stds. (NAAQS) were set and implemented;. (3) 1977-1993, A period of the first revisions to the stds., new CAA Amendments, delays in implementation and decision-making, and key science/policy/legislative developments that would alter both the focus and scale of air pollution programs and how they are implemented; and. (4) 1993-2006, The second and third wave of NAAQS revisions and their implementation in the context of the 1990 CAA. This discussion examines where NAAQS have helped drive implementation programs and how improvements in both effects and air quality/control sciences influenced policy and legislation to enhance the effectiveness of the system over time. The review concludes with a look toward the future of AQM, emphasizing challenges and ways to meet them. The most significant of these is the need to make more efficient progress toward air quality goals, while adjusting the system to address the growing intersections between air quality management and climate change.

(Massachusetts Medical Society)Exposure to fine-particulate air pollution has been assocd. with increased morbidity and mortality, suggesting that sustained redns. in pollution exposure should result in improved life expectancy. This study directly evaluated the changes in life expectancy assocd. with differential changes in fine-particulate air pollution that occurred in the United States during the 1980s and 1990s. The authors compiled data on life expectancy, socioeconomic status, and demog. characteristics for 211 county units in the 51 U.S. metropolitan areas with matching data on fine-particulate air pollution for the late 1970s and early 1980s and the late 1990s and early 2000s. Regression models were used to est. the assocn. between redns. in pollution and changes in life expectancy, with adjustment for changes in socioeconomic and demog. variables and in proxy indicators for the prevalence of cigarette smoking. A decrease of 10 μg per cubic meter in the concn. of fine particulate matter was assocd. with an estd. increase in mean (± SE) life expectancy of 0.61 ± 0.20 yr (P = 0.004). The estd. effect of reduced exposure to pollution on life expectancy was not highly sensitive to adjustment for changes in socioeconomic, demog., or proxy variables for the prevalence of smoking or to the restriction of observations to relatively large counties. Redns. in air pollution accounted for as much as 15% of the overall increase in life expectancy in the study areas. A redn. in exposure to ambient fine-particulate air pollution contributed to significant and measurable improvements in life expectancy in the United States.

(American Chemical Society)Ambient fine particulate matter (PM2.5) is a leading environmental risk factor for premature mortality. This work used aerosol optical depth (AOD) measurements from 2 satellite instruments, multi-angle imaging spectroradiometer and sea viewing wide field of vision sensor, to produce a unified 15-yr global time series (1998-2012) of ground-level PM2.5 concns. at a 1° x 1° resoln. The GEOS-chem chem. transport model related each individual AOD retrieval to ground-level PM2.5 concn. Four broad areas displaying significant, spatially coherent, annual trends were examd. in detail: eastern USA (-0.39 ± 0.10 μg/m3-yr), Arabian Peninsula (0.81 ± 0.21 μg/m3-yr), southern Asia (0.93 ± 0.22 μg/m3-yr), and eastern Asia (0.79 ± 0.27 μg/m3-yr). Over the dense in-situ observation period, 1999-2012, the linear tendency for the eastern USA (-0.37 ± 0.13 μg/m3-yr) agreed well with in-situ measurements (-0.38 ± 0.06 μg/m3-yr). A GEOS-Chem simulation showed secondary inorg. aerosols largely explained the obsd. PM2.5 trend over the eastern USA and southern and eastern Asia; mineral dust largely explained the obsd. trend over the Arabian Peninsula.

(Springer)In Jan. 2013, a long-lasting episode of severe haze occurred in central and eastern China, and it attracted attention from all sectors of society. The process and evolution of haze pollution episodes were obsd. by the "Forming Mechanism and Control Strategies of Haze in China" group using an intensive aerosol and trace gases campaign that simultaneously obtained data at 11 ground-based observing sites in the CARE-China network. The characteristics and formation mechanism of haze pollution episodes were discussed. Five haze pollution episodes were identified in the Beijing-Tianjin-Hebei (Jing-Jin-Ji) area; the two most severe episodes occurred during 9-15 Jan. and 25-31 Jan. During these two haze pollution episodes, the max. hourly PM2.5 mass concns. in Beijing were 680 and 530 μg m-3, resp. The process and evolution of haze pollution episodes in other major cities in the Jing-Jin-Ji area, such as Shijiazhuang and Tianjin were almost the same as those obsd. in Beijing. The external cause of the severe haze episodes was the unusual atm. circulation, the depression of strong cold air activities and the very unfavorable dispersion due to geog. and meteorol. conditions. However, the internal cause was the quick secondary transformation of primary gaseous pollutants to secondary aerosols, which contributed to the "explosive growth" and "sustained growth" of PM2.5. Particularly, the abnormally high amt. of nitric oxide (NOx) in the haze episodes, produced by fossil fuel combustion and vehicle emissions, played a direct or indirect role in the quick secondary transformation of coal-burning sulfur dioxide (SO2) to sulfate aerosols. Furthermore, gaseous pollutants were transformed into secondary aerosols through heterogeneous reactions on the surface of fine particles, which can change the particle's size and chem. compn. Consequently, the proportion of secondary inorg. ions, such as sulfate and nitrate, gradually increased, which enhances particle hygroscopicity and thereby accelerating formation of the haze pollution.

(Wiley-Blackwell)This anal. provides an up-to-date assessment of long-term (1990-2010) rural ozone trends using all available data in the Western (12 sites) and Eastern (41 sites) USA. Rather than focus solely on av. ozone values or air quality std. violations, we consider the full range of ozone values, reporting trends for the 5th, 50th and 95th percentiles. Domestic ozone precursor emissions decreased strongly during 1990-2010. Accordingly 83%, 66% and 20% of summertime eastern U.S. sites experienced statistically significant ozone decreases in the 95th, 50th and 5th percentiles, resp. During spring 43% of the eastern sites have statistically significant ozone decreases for the 95th percentile with no sites showing a significant increase. At the 50th percentile there is little overall change in the Eastern U.S. In contrast, only 17% (2 sites) and 8% (1 site) of summertime Western U.S. sites have statistically significant ozone decreases in the 95th and 50th percentiles, resp. During spring no western site has a significant decrease, while 50% have a significant median increase. This dichotomy in U.S. ozone trends is discussed in terms of changing anthropogenic and biomass burning emissions. Consideration is given to the concept that increasing baseline ozone flowing into the western U.S. is counteracting ozone redns. due to domestic emission redns. An update to the springtime free tropospheric ozone trend above western North America shows that ozone has increased significantly from 1995 to 2011 at the rate of 0.41 ± 0.27 ppbv yr-1. Finally, the ozone changes are examd. in relation to regional temp. trends.

P.Atmospheric Chemistry and Physics (2013), 13 (8), 4145-4169, 25 pp.CODEN: ACPTCE; ISSN:1680-7324. (Copernicus Publications)Tropospheric NO2, a key pollutant in particular in cities, has been measured from space since the mid-1990s by the GOME, SCIAMACHY, OMI, and GOME-2 instruments. These data provide a unique global long-term dataset of tropospheric pollution. However, the observations differ in spatial resoln., local time of measurement, viewing geometry, and other details. All these factors can severely impact the retrieved NO2 columns. In this study, we present three ways to account for instrumental differences in trend analyses of the NO2 columns derived from satellite measurements, while preserving the individual instruments' spatial resolns. For combining measurements from GOME and SCIAMACHY into one consistent time series, we develop a method to explicitly account for the instruments' difference in ground pixel size (40 × 320 km2 vs. 30 × 60 km2). This is esp. important when analyzing NO2 changes over small, localised sources like, e.g. megacities. The method is based on spatial averaging of the measured earthshine spectra and extn. of a spatial pattern of the resoln. effect. Furthermore, two empirical corrections, which summarise all instrumental differences by including instrument-dependent offsets in a fitted trend function, are developed. These methods are applied to data from GOME and SCIAMACHY sep., to the combined time series, and to an extended dataset comprising also GOME-2 and OMI measurements. All approaches show consistent trends of tropospheric NO2 for a selection of areas on both regional and city scales, for the first time allowing consistent trend anal. of the full time series at high spatial resoln. Compared to previous studies, the longer study period leads to significantly reduced uncertainties. We show that measured tropospheric NO2 columns have been strongly increasing over China, the Middle East, and India, with values over east-central China tripling from 1996 to 2011. All parts of the developed world, including Western Europe, the United States, and Japan, show significantly decreasing NO2 amts. in the same time period. On a megacity level, individual trends can be as large as +27.2 ± 3.9 %yr-1 and +20.7 ± 1.9 %yr-1 in Dhaka and Baghdad, resp., while Los Angeles shows a very strong decrease of -6.00 ± 0.72 %yr-1. Most megacities in China, India, and the Middle East show increasing NO2 columns of +5 to 10 %yr-1, leading to a doubling to tripling within the study period.

(U. S. Department of Health and Human Services, National Institutes of Health)Background: Air pollution is assocd. with morbidity and premature mortality. Satellite remote sensing provides globally consistent decadal-scale observations of ambient nitrogen dioxide (NO2) pollution. Objective: We detd. global population-weighted annual mean NO2 concns. from 1996 through 2012. Methods: We used observations of NO2 tropospheric column densities from three satellite instruments in combination with chem. transport modeling to produce a global 17-yr record of ground-level NO2 at 0.1 ° × 0.1 ° resoln. We calcd. linear trends in population-weighted annual mean NO2 (PWMNO2) concns. in different regions around the world. Results: We found that PWMNO2 in high-income North America (Canada and the United States) decreased more steeply than in any other region, having declined at a rate of -4.7%/yr [95% confidence interval (CI): -5.3, -4.1]. PWMNO2 decreased in western Europe at a rate of -2.5%/yr (95% CI: -3.0, -2.1). The highest PWMNO2 occurred in high-income Asia Pacific (predominantly Japan and South Korea) in 1996, with a subsequent decrease of -2.1%/yr (95% CI: -2.7, -1.5). In contrast, PWMNO2 almost tripled in East Asia (China, North Korea, and Taiwan) at a rate of 6.7%/yr (95% CI: 6.0, 7.3). The satellite-derived ests. of trends in ground-level NO2 were consistent with regional trends inferred from data obtained from ground-station monitoring networks in North America (within 0.7%/yr) and Europe (within 0.3%/yr). Our rankings of regional av. NO2 and long-term trends differed from the satellite-derived ests. of fine particulate matter reported elsewhere, demonstrating the utility of both indicators to describe changing pollutant mixts. Conclusions: Long-term trends in satellite-derived ambient NO2 provide new information about changing global exposure to ambient air pollution.

J.; Cofala, J.Environmental Research Letters (2013), 8 (1), 014003CODEN: ERLNAL; ISSN:1748-9326. (IOP Publishing Ltd.)The evolution of global and regional anthropogenic SO2 emissions in the last decade has been estd. through a bottom-up calcn. After increasing until about 2006, we est. a declining trend continuing until 2011. However, there is strong spatial variability, with North America and Europe continuing to reduce emissions, with an increasing role of Asia and international shipping. China remains a key contributor, but the introduction of stricter emission limits followed by an ambitious program of installing flue gas desulfurization on power plants resulted in a significant decline in emissions from the energy sector and stabilization of total Chinese SO2 emissions. Comparable mitigation strategies are not yet present in several other Asian countries and industrial sectors in general, while emissions from international shipping are expected to start declining soon following an international agreement to reduce the sulfur content of fuel oil. The estd. trends in global SO2 emissions are within the range of representative concn. pathway (RCP) projections and the uncertainty previously estd. for the year 2005.

(IOP Publishing Ltd.)Emissions of gases and particles from the combustion of fossil fuels and biofuels in Africa are expected to increase significantly in the near future due to the rapid growth of African cities and megacities. There is currently no regional emissions inventory that provides ests. of anthropogenic combustion for the African continent. This work provides a quantification of the evolution of African combustion emissions from 2005 to 2030, using a bottom-up method. This inventory predicts very large increases in black carbon, org. carbon, CO, NOx, SO2 and non-methane hydrocarbon emissions if no emission regulations are implemented. This paper discusses the effectiveness of scenarios involving certain fuels, specific to Africa in each activity sector and each region (western, eastern, northern and southern Africa), to reduce the emissions. The estd. trends in African emissions are consistent with emissions provided by global inventories, but they display a larger range of values. African combustion emissions contributed significantly to global emissions in 2005. This contribution will increase more significantly by 2030: org. carbon emissions will for example make up 50% of the global emissions in 2030. Furthermore, we show that the magnitude of African anthropogenic emissions could be similar to African biomass burning emissions around 2030.

(Taylor & Francis Ltd.)Multiple linkages connect air quality and climate change. Many air pollutant sources also emit carbon dioxide (CO2), the dominant anthropogenic greenhouse gas (GHG). The two main contributors to non-attainment of U. S. ambient air quality stds., ozone (O3) and particulate matter (PM), interact with radiation, forcing climate change. PM warms by absorbing sunlight (e.g., black carbon) or cools by scattering sunlight (e.g., sulfates) and interacts with clouds; these radiative and microphys. interactions can induce changes in pptn. and regional circulation patterns. Climate change is expected to degrade air quality in many polluted regions by changing air pollution meteorol. (ventilation and diln.), pptn. and other removal processes, and by triggering some amplifying responses in atm. chem. and in anthropogenic and natural sources. Together, these processes shape distributions and extreme episodes of O3 and PM. Global modeling indicates that as air pollution programs reduce SO2 to meet health and other air quality goals, near-term warming accelerates due to "unmasking" of warming induced by rising CO2. Air pollutant controls on CH4, a potent GHG and precursor to global O3 levels, and on sources with high black carbon (BC) to org. carbon (OC) ratios could offset near-term warming induced by SO2 emission redns., while reducing global background O3 and regionally high levels of PM. Lowering peak warming requires decreasing atm. CO2, which for some source categories would also reduce co-emitted air pollutants or their precursors. Model projections for alternative climate and air quality scenarios indicate a wide range for U. S. surface O3 and fine PM, although regional projections may be confounded by interannual to decadal natural climate variability. Continued implementation of U. S. NOx emission controls guards against rising pollution levels triggered either by climate change or by global emission growth. Improved accuracy and trends in emission inventories are crit. for accountability analyses of historical and projected air pollution and climate mitigation policies. Implications: The expansion of U. S. air pollution policy to protect climate provides an opportunity for joint mitigation, with CH4 a prime target. BC redns. in developing nations would lower the global health burden, and for BC-rich sources (e.g., diesel) may lessen warming. Controls on these emissions could offset near-term warming induced by health-motivated redns. of sulfate (cooling). Wildfires, dust, and other natural PM and O3 sources may increase with climate warming, posing challenges to implementing and attaining air quality stds. Accountability analyses for recent and projected air pollution and climate control strategies should underpin estd. benefits and trade-offs of future policies.

(National Academy of Sciences)Recent bursts in the incidence of large wildfires worldwide have raised concerns about the influence climate change and humans might have on future fire activity. Comparatively little is known, however, about the relative importance of these factors in shaping global fire history. Here we use fire and climate modeling, combined with land cover and population ests., to gain a better understanding of the forces driving global fire trends. Our model successfully .reproduces global fire activity record over the last millennium and reveals distinct regimes in global fire behavior. We find that during the preindustrial period, the global fire regime was strongly driven by pptn. (rather than temp.), shifting to an anthropogenic-driven regime with the Industrial Revolution. Our future projections indicate an impending shift to a temp.-driven global fire regime in the 21st century, creating an unprecedentedly fire-prone environment. These results suggest a possibility that in the future climate will play a considerably stronger role in driving global fire trends, outweighing direct human influence on fire (both ignition and suppression), a reversal from the situation during the last two centuries.

(John Wiley & Sons, Inc.)A review. Proton-transfer-reaction mass spectrometry (PTR-MS) allows real-time measurements of volatile org. compds. (VOCs) in air with a high sensitivity and a fast time response. The use of PTR-MS in atm. research has expanded rapidly in recent years, and much has been learned about the instrument response and specificity of the technique in the anal. of air from different regions of the atm. This paper aims to review the progress that has been made. The theory of operation is described and allows the response of the instrument to be described for different operating conditions. More accurate detns. of the instrument response involve calibrations using std. mixts., and some results are shown. Much has been learned about the specificity of PTR-MS from inter-comparison studies as well the coupling of PTR-MS with a gas chromatog. interface. The literature on this issue is reviewed and summarized for many VOCs of atm. interest. Some highlights of airborne measurements by PTR-MS are presented, including the results obtained in fresh and aged forest-fire and urban plumes. Finally, the recent work that is focused on improving the technique is discussed.

(American Association for the Advancement of Science)Org. aerosol (OA) particles affect climate forcing and human health, but their sources and evolution are poorly characterized. A unifying model framework describing the atm. evolution of OA which is constrained by high time resolved measurements of its compn., volatility, and oxidn. state is presented. OA and OA precursor gases evolve by becoming increasingly oxidized, less volatile, and more hygroscopic, leading to the formation of oxygenated org. aerosols (OOA), with concns. comparable to those of SO42- aerosols throughout the Northern Hemisphere. This model framework captures the dynamic aging behavior obsd. in the atm. and lab.; it serves as a basis to improve regional and global model parameterizations.

(Nature Publishing Group)Heterogeneous reactions of O3 with aerosol particles are of central importance to air quality. They are studied extensively, but mol. mechanisms and kinetics are unresolved. Based on new exptl. data and calcns., this work showed long-lived reactive O intermediates (ROI) are formed. The chem. lifetime of these intermediates is >100 s, much longer than the surface residence time of mol. O3 (∼10-9 s). ROI explain and resolve apparent discrepancies between earlier quantum mech. calcns. and kinetic expts. They play a key role in the chem. transformation and adverse health effects of toxic, allergenic airborne particulate matter, e.g., soot, polycyclic arom. hydrocarbons, and proteins. ROI may also be involved in the decompn. of O3 on mineral dust and in formation and growth of secondary org. aerosols. Also, ROI may contribute to the coupling of atm. and biospheric multi-phase processes.

(Copernicus Publications)We assess the potential of the water-sol. fraction of atm. fine aerosols in the Southeastern United States to generate reactive oxygen species (ROS) and identify major ROS-assocd. emission sources. ROS-generation potential of particles was quantified by the dithiothreitol (DTT) assay and involved anal. of fine particulate matter (PM) extd. from high-vol. quartz filters (23 h integrated samples) collected at various sites in different environmental settings in the southeast, including three urban-Atlanta sites, in addn. to a rural site. Paired sampling was conducted with one fixed site in Atlanta (Jefferson Street), representative of the urban environment, with the others rotating among different sites, for ∼250 days between June 2012 and Sept. 2013 (N = 483). A simple linear regression between the DTT activity and aerosol chem. components revealed strong assocns. between PM ROSgeneration potential and secondary org. aerosol (WSOC - water-sol. org. carbon) in summer, and biomass burning markers in winter. Redox-active metals were also somewhat correlated with the DTT activity, but mostly at urban and roadside sites. Pos. matrix factorization (PMF) was applied to apportion the relative contribution of various sources to the ROS-generation potential of water-sol. PM2.5 in urban Atlanta. PMF showed that vehicular emissions contribute uniformly throughout the year (12-25 %), while secondary oxidn. processes dominated the DTT activity in summer (46%) and biomass burning in winter (47%). Road dust was significant only during drier periods (∼12% in summr and fall). Source apportionment by chem. mass balance (CMB) was reasonably consistent with PMF, but with higher contribution from vehicular emissions (32%). Given the spatially large data set of PM sampled over an extended period, the study reconciles the results from previous work that showed only region- or season-specific aerosol components or sources contributing to PM ROS activity, possibly due to smaller sample sizes. The ubiquitous nature of the major sources of PM-assocd. ROS suggests widespread population exposures to aerosol components that have the ability to catalyze the prodn. of oxidants in vivo.

(American Chemical Society)The air pollution monitoring paradigm is rapidly changing due to recent advances in: development of portable, lower-cost air pollution sensors which report data in near-real time at high-time resoln.; increased computational and visualization capabilities; and wireless communication/infrastructure. It is possible these advances can support traditional air quality monitoring by supplementing ambient air monitoring and enhancing compliance monitoring. Sensors are beginning to provide individuals and communities necessary tools to understand their environmental exposure; these individual and community-based data strategies can be developed to reduce pollution exposure and to understand links to health indicators. Topics discussed include: current state of sensor science; supplementing routine ambient air monitoring networks; expanding the conversation with communities and citizens; enhancing source compliance monitoring; monitoring personal exposure; challenges; and opportunities for solns.: a changing role for government.

(American Chemical Society)Land use regression (LUR) is used to map air pollutant concn. spatial variability for risk assessment, epidemiol., and air quality management. Conventional LUR requires long-term measurements at multiple sites, so application to particulate matter has been limited. Mobile monitoring characterized spatial variability in carbon black concns. for LUR modeling. A particle soot absorption photometer in a moving vehicle measured the absorption coeff. (σap) in summer during peak afternoon traffic at 39 sites. LUR modeled the mean and 25th, 50th, 75th, and 90th percentile values of the distribution of 10-s measurements for each site. Model performance (detd. by R2) was higher for the 25th and 50th percentiles (0.72 and 0.68, resp.) than for the mean, 75th, and 90th percentiles (0.51, 0.55, and 0.54, resp.). Performance was similar to that reported for conventional LUR models of NO2 and NO in this region (116 sites) and better than that for mean σap from fixed-location samplers (25 sites). Models of the mean, 75th, and 90th percentiles favored predictors describing truck, rather than total, traffic. This approach is applicable to other urban areas to facilitate development of LUR models for particulate matter.

L.Atmospheric Environment (2013), 70 (), 186-203CODEN: AENVEQ; ISSN:1352-2310. (Elsevier Ltd.)Measurements at appropriate spatial and temporal scales are essential for understanding and monitoring spatially heterogeneous environments with complex and highly variable emission sources, such as in urban areas. However, the costs and complexity of conventional air quality measurement methods means that measurement networks are generally extremely sparse. In this paper we show that miniature, low-cost electrochem. gas sensors, traditionally used for sensing at parts-per-million (ppm) mixing ratios can, when suitably configured and operated, be used for parts-per-billion (ppb) level studies for gases relevant to urban air quality. Sensor nodes, in this case consisting of multiple individual electrochem. sensors, can be low-cost and highly portable, thus allowing the deployment of scalable high-d. air quality sensor networks at fine spatial and temporal scales, and in both static and mobile configurations. In this paper we provide evidence for the performance of electrochem. sensors at the parts-per-billion level, and then outline results obtained from deployments of networks of sensor nodes in both an autonomous, high-d., static network in the wider Cambridge (UK) area, and as mobile networks for quantification of personal exposure. Examples are presented of measurements obtained with both highly portable devices held by pedestrians and cyclists, and static devices attached to street furniture. The widely varying mixing ratios reported by this study confirm that the urban environment cannot be fully characterised using sparse, static networks, and that measurement networks with higher resoln. (both spatially and temporally) are required to quantify air quality at the scales which are present in the urban environment. We conclude that the instruments described here, and the low-cost/high-d. measurement philosophy which underpins it, have the potential to provide a far more complete assessment of the high-granularity air quality structure generally obsd. in the urban environment, and could ultimately be used for quantification of human exposure as well as for monitoring and legislative purposes.

OBJECTIVE: In this study, we developed improved global exposure estimates of ambient PM2.5 mass and trend using PM2.5 concentrations inferred from multiple satellite instruments. METHODS: We combined three satellite-derived PM2.5 sources to produce global PM2.5 estimates at about 10 km × 10 km from 1998 through 2012. For each source, we related total column retrievals of aerosol optical depth to near-ground PM2.5 using the GEOS-Chem chemical transport model to represent local aerosol optical properties and vertical profiles. We collected 210 global ground-based PM2.5 observations from the literature to evaluate our satellite-based estimates with values measured in areas other than North America and Europe. RESULTS: We estimated that global population-weighted ambient PM2.5 concentrations increased 0.55 μg/m3/year (95% CI: 0.43, 0.67) (2.1%/year; 95% CI: 1.6, 2.6) from 1998 through 2012. Increasing PM2.5 in some developing regions drove this global change, despite decreasing PM2.5 in some developed regions. The estimated proportion of the population of East Asia living above the World Health Organization (WHO) Interim Target-1 of 35 μg/m3 increased from 51% in 1998-2000 to 70% in 2010-2012. In contrast, the North American proportion above the WHO Air Quality Guideline of 10 μg/m3 fell from 62% in 1998-2000 to 19% in 2010-2012. We found significant agreement between satellite-derived estimates and ground-based measurements outside North America and Europe (r = 0.81; n = 210; slope = 0.68). The low bias in satellite-derived estimates suggests that true global concentrations could be even greater. CONCLUSIONS: Satellite observations provide insight into global long-term changes in ambient PM2.5 concentrations. Satellite-derived estimates and ground-based PM2.5 observations from this study are available for public use.

(Elsevier Ltd.)The use of satellite-based aerosol optical depth (AOD) to est. fine particulate matter (PM2.5) for epidemiol. studies has increased substantially over the past few years. These recent studies often report moderate predictive power, which can generate downward bias in effect ests. In addn., AOD measurements have only moderate spatial resoln., and have substantial missing data. We make use of recent advances in MODIS satellite data processing algorithms Multi-Angle Implementation of Atm. Correction (MAIAC), which allow us to use 1 km (vs. currently available 10 km) resoln. AOD data. We developed and cross validated models to predict daily PM2.5 at a 1 × 1 km resoln. across the northeastern USA (New England, New York and New Jersey) for the years 2003-2011, allowing us to better differentiate daily and long term exposure between urban, suburban, and rural areas. Addnl., we developed an approach that allows us to generate daily high-resoln. 200 m localized predictions representing deviations from the area 1 × 1 km grid predictions. We used mixed models regressing PM2.5 measurements against day-specific random intercepts, and fixed and random AOD and temp. slopes. We then use generalized additive mixed models with spatial smoothing to generate grid cell predictions when AOD was missing. Finally, to get 200 m localized predictions, we regressed the residuals from the final model for each monitor against the local spatial and temporal variables at each monitoring site. Our model performance was excellent (mean out-of-sample R2 = 0.88). The spatial and temporal components of the out-of-sample results also presented very good fits to the withheld data (R2 = 0.87, R2 = 0.87). In addn., our results revealed very little bias in the predicted concns. (Slope of predictions vs. withheld observations = 0.99). Our daily model results show high predictive accuracy at high spatial resolns. and will be useful in reconstructing exposure histories for epidemiol. studies across this region.

(American Chemical Society)Estg. ground-level PM2.5 from satellite-derived aerosol optical depth (AOD) using a spatial statistical model is a promising new method to evaluate the spatial and temporal characteristics of PM2.5 exposure in a large geog. region. However, studies outside North America have been limited due to the lack of ground PM2.5 measurements to calibrate the model. Taking advantage of the newly established national monitoring network, we developed a national-scale geog. weighted regression (GWR) model to est. daily PM2.5 concns. in China with fused satellite AOD as the primary predictor. The results showed that the meteorol. and land use information can greatly improve model performance. The overall cross-validation (CV) R2 is 0.64 and root mean squared prediction error (RMSE) is 32.98 μg/m3. The mean prediction error (MPE) of the predicted annual PM2.5 is 8.28 μg/m3. Our predicted annual PM2.5 concns. indicated that over 96% of the Chinese population lives in areas that exceed the Chinese National Ambient Air Quality Std. (CNAAQS) Level 2 std. Our results also confirmed satellite-derived AOD in conjunction with meteorol. fields and land use information can be successfully applied to extend the ground PM2.5 monitoring network in China.

(American Association for the Advancement of Science)Many types of aerosols have lifetimes long enough for their transcontinental transport, making them potentially important contributors to air quality and climate change in remote locations. We est. that the mass of aerosols arriving at North American shores from overseas is comparable with the total mass of particulates emitted domestically. Curbing domestic emissions of particulates and precursor gases, therefore, is not sufficient to mitigate aerosol impacts in North America. The imported contribution is dominated by dust leaving Asia, not by combustion-generated particles. Thus, even a redn. of industrial emissions of the emerging economies of Asia could be overwhelmed by an increase of dust emissions due to changes in meteorol. conditions and potential desertification.

JasonAir Quality, Atmosphere & Health (2013), 6 (3), 563-573CODEN: AQAHAX; ISSN:1873-9326. (Springer)Assessments of human health impacts assocd. with outdoor air pollution often use air quality models to represent exposure, but involve uncertainties due to coarse model resoln. Here, we quantify how ests. of mortality in the USA attributable to ozone (O3) and fine particulate matter (PM2.5) at coarse resoln. differ from those at finer resoln. Using the finest modeled concns. (12 km), we est. that 66,000 (95% CI, 39,300-84,500) all-cause and 21,400 (5,600-34,200) respiratory deaths per yr are attributable to PM2.5 and O3 concns. above low-concn. thresholds, resp. Using model results at 36 km resoln. gives mortality burdens that are 11 % higher for PM2.5 and 12% higher for O3 than the 12-km ests., suggesting a modest pos. bias. We also scale modeled concns. at 12 km to coarser resolns. by simple averaging and repeat the mortality assessment at multiple resolns. from 24 to 408 km, including the resolns. of global models; in doing so, we account for the effect of resoln. on population exposure. Coarse grid resolns. produce mortality ests. that are substantially biased low for PM2.5 (30-40 % lower than the 12-km est. at >250 km resoln.), but less than 6% higher for O3 at any resoln. Mortality ests. for primary PM2.5 species show greater bias at coarse resoln. than secondary species. These results suggest that coarse resoln. global models (>100 km) are likely biased low for PM2.5 health effects. For ozone, biases due to coarse resoln. may be much smaller, and the effect on modeled chem. likely dominates.

(National Academy of Sciences)Isoprene is a significant source of atm. org. aerosol; however, the oxidn. pathways that lead to secondary org. aerosol (SOA) have remained elusive. Here, we identify the role of two key reactive intermediates, epoxydiols of isoprene (IEPOX = β-IEPOX + δ-IEPOX) and methacryloylperoxynitrate (MPAN), which are formed during isoprene oxidn. under low- and high-NOx conditions, resp. Isoprene low-NOx SOA is enhanced in the presence of acidified sulfate seed aerosol (mass yield 28.6%) over that in the presence of neutral aerosol (mass yield 1.3%). Increased uptake of IEPOX by acid-catalyzed particle-phase reactions is shown to explain this enhancement. Under high-NOx conditions, isoprene SOA formation occurs through oxidn. of its second-generation product, MPAN. The similarity of the compn. of SOA formed from the photooxidn. of MPAN to that formed from isoprene and methacrolein demonstrates the role of MPAN in the formation of isoprene high-NOx SOA. Reactions of IEPOX and MPAN in the presence of anthropogenic pollutants (i.e., acidic aerosol produced from the oxidn. of SO2 and NO2, resp.) could be a substantial source of "missing urban SOA" not included in current atm. models.

(European Geosciences Union)Data from a recent field campaign in Mexico City are used to evaluate the performance of the EPA Federal Ref. Method for monitoring the ambient concns. of NO2. Measurements of NO2 from std. chemiluminescence monitors equipped with molybdenum oxide converters are compared with those from Tunable IR Laser Differential Absorption Spectroscopy (TILDAS) and Differential Optical Absorption Spectroscopy (DOAS) instruments. A significant interference in the chemiluminescence measurement is shown to account for up to 50% of ambient NO2 concn. during afternoon hours. As expected, this interference correlates well with non-NOx reactive nitrogen species (NOz) as well as with ambient O3 concns., indicating a photochem. source for the interfering species. A combination of ambient gas phase nitric acid and alkyl and multifunctional alkyl nitrates is deduced to be the primary cause of the interference. Observations at four locations at varying proximities to emission sources indicate that the percentage contribution of HNO3 to the interference decreases with time as the air parcel ages. Alkyl and multifunctional alkyl nitrate concns. are calcd. to reach concns. as high as several ppb inside the city, on par with the highest values previously obsd. in other urban locations. Averaged over the MCMA-2003 field campaign, the chemiluminescence monitor interference resulted in an av. measured NO2 concn. up to 22% greater than that from co-located spectroscopic measurements. Thus, this interference has the potential to initiate regulatory action in areas that are close to non-attainment and may mislead atm. photochem. models used to assess control strategies for photochem. oxidants.

(Massachusetts Medical Society)Although many studies have linked elevations in tropospheric ozone to adverse health outcomes, the effect of long-term exposure to ozone on air pollution-related mortality remains uncertain. The authors examd. the potential contribution of exposure to ozone to the risk of death from cardiopulmonary causes and specifically to death from respiratory causes. Data from the study cohort of the American Cancer Society Cancer Prevention Study II were correlated with air-pollution data from 96 metropolitan statistical areas in the United States. Data were analyzed from 448,850 subjects, with 118,777 deaths in an 18-yr follow-up period. Data on daily max. ozone concns. were obtained from Apr. 1 to Sept. 30 for the years 1977 through 2000. Data on concns. of fine particulate matter (particles that are ≤2.5 μm in aerodynamic diam. [PM2.5]) were obtained for the years 1999 and 2000. Assocns. between ozone concns. and the risk of death were evaluated with the use of std. and multilevel Cox regression models. In single-pollutant models, increased concns. of either PM2.5 or ozone were significantly assocd. with an increased risk of death from cardiopulmonary causes. In two-pollutant models, PM2.5 was assocd. with the risk of death from cardiovascular causes, whereas ozone was assocd. with the risk of death from respiratory causes. The estd. relative risk of death from respiratory causes that was assocd. with an increment in ozone concn. of 10 ppb was 1.040 (95% confidence interval, 1.010-1.067). The assocn. of ozone with the risk of death from respiratory causes was insensitive to adjustment for confounders and to the type of statistical model used. Thus, in this large study, the authors were not able to detect an effect of ozone on the risk of death from cardiovascular causes when the concn. of PM2.5 was taken into account. The authors did, however, demonstrate a significant increase in the risk of death from respiratory causes in assocn. with an increase in ozone concn.

(Elsevier Ltd.)Few studies on long-term exposure to air pollution and mortality have been reported from Europe. Within the multicenter European Study of Cohorts for Air Pollution Effects (ESCAPE), we aimed to investigate the assocn. between natural-cause mortality and long-term exposure to several air pollutants.We used data from 22 European cohort studies, which created a total study population of 367,251 participants. All cohorts were general population samples, although some were restricted to one sex only. With a strictly standardized protocol, we assessed residential exposure to air pollutants as annual av. concns. of particulate matter (PM) with diams. of less than 2.5 μm (PM2.5), less than 10 μm (PM10), and between 10 μm and 2.5 μm (PMcoarse), PM2.5 absorbance, and annual av. concns. of nitrogen oxides (NO2 and NOx), with land use regression models. We also investigated two traffic intensity variables-traffic intensity on the nearest road (vehicles per day) and total traffic load on all major roads within a 100 m buffer. We did cohort-specific statistical analyses using confounder models with increasing adjustment for confounder variables, and Cox proportional hazards models with a common protocol. We obtained pooled effect ests. through a random-effects meta-anal.The total study population consisted of 367,251 participants who contributed 5,118,039 person-years at risk (av. follow-up 13.9 years), of whom 29,076 died from a natural cause during follow-up. A significantly increased hazard ratio (HR) for PM2.5 of 1.07 (95% CI 1.02-1.13) per 5 μg/m3 was recorded. No heterogeneity was noted between individual cohort effect ests. (I2 p value=0.95). HRs for PM2·5 remained significantly raised even when we included only participants exposed to pollutant concns. lower than the European annual mean limit value of 25 μg/m3 (HR 1.06, 95% CI 1.00-1.12) or below 20 μg/m3 (1.07, 1.01-1.13).Long-term exposure to fine particulate air pollution was assocd. with natural-cause mortality, even within concn. ranges well below the present European annual mean limit value.

The chemical composition of particles varies across locations and time periods. Identifying the most harmful constituents and sources is an important health and regulatory concern. OBJECTIVES: We examined pollutant sources for associations with risk of hospital admissions for cardiovascular and respiratory causes. METHODS: We obtained PM2.5 filter samples for four counties in Connecticut and Massachusetts and analyzed them for PM2.5 elements. Source apportionment was used to estimate daily PM2.5 contributions from sources (traffic, road dust, oil combustion, and sea salt as well as a regional source representing coal combustion and other sources). Associations between daily PM2.5 constituents and sources and risk of cardiovascular and respiratory hospitalizations for the Medicare population (> 333,000 persons ≥ 65 years of age) were estimated with time-series analyses (August 2000-February 2004). RESULTS: PM2.5 total mass and PM2.5 road dust contribution were associated with cardiovascular hospitalizations, as were the PM2.5 constituents calcium, black carbon, vanadium, and zinc. For respiratory hospitalizations, associations were observed with PM2.5 road dust, and sea salt as well as aluminum, calcium, chlorine, black carbon, nickel, silicon, titanium, and vanadium. Effect estimates were generally robust to adjustment by co-pollutants of other constituents. An interquartile range increase in same-day PM2.5 road dust (1.71 μg/m3) was associated with a 2.11% (95% CI: 1.09, 3.15%) and 3.47% (95% CI: 2.03, 4.94%) increase in cardiovascular and respiratory admissions, respectively. CONCLUSIONS: Our results suggest some particle sources and constituents are more harmful than others and that in this Connecticut/Massachusetts region the most harmful particles include black carbon, calcium, and road dust PM2.5.

(National Academy of Sciences)Air pollution in China and other parts of Asia poses large health risks and is an important contributor to global climate change. Almost half of Chinese homes use biomass and coal fuels for cooking and heating. China's economic growth and infrastructure development has led to increased emissions from coal-fired power plants and an expanding fleet of motor vehicles. Black carbon (BC) from incomplete biomass and fossil fuel combustion is the most strongly light-absorbing component of particulate matter (PM) air pollution and the second most important climate-forcing human emission. PM compn. and sources may also be related to its human health impact. We enrolled 280 women living in a rural area of northwestern Yunnan where biomass fuels are commonly used. We measured their blood pressure, distance from major traffic routes, and daily exposure to BC (pyrolytic biomass combustion), water-sol. org. aerosol (org. aerosol from biomass combustion), and, in a subset, hopane markers (motor vehicle emissions) in winter and summer. BC had the strongest assocn. with systolic blood pressure (SBP) (4.3 mm Hg; P < 0.001), followed by PM mass and water-sol. org. mass. The effect of BC on SBP was almost three times greater in women living near the highway [6.2 mm Hg ; 95% confidence interval (CI), 3.6 to 8.9 vs. 2.6 mm Hg ; 95% CI, 0.1 to 5.2]. Our findings suggest that BC from combustion emissions is more strongly assocd. with blood pressure than PM mass, and that BC's health effects may be larger among women living near a highway and with greater exposure to motor vehicle emissions.

(2015), 26 (3), 321-7 ISSN:.BACKGROUND: Fine particulate (PM2.5) air pollution has been consistently linked to survival, but reported effect estimates are geographically heterogeneous. Exposure to different types of particle mixtures may explain some of this variation. METHODS: We used k-means cluster analyses to identify cities with similar pollution profiles, (ie, PM2.5 composition) across the United States. We examined the impact of PM2.5 on survival, and its variation across clusters of cities with similar PM2.5 composition, among Medicare enrollees in 81 US cities (2000-2010). We used time-varying annual PM2.5 averages, measured at ambient central monitoring sites, as the exposure of interest. We ran by-city Cox models, adjusting for individual data on previous cardiopulmonary-related hospitalizations and stratifying by follow-up time, age, gender, and race. This eliminates confounding by factors varying across cities and long-term trends, focusing on year-to-year variations of air pollution around its city-specific mean and trend. We then pooled the city-specific effects using a random effects meta-regression. In this second stage, we also assessed effect modification by cluster membership and estimated cluster-specific PM2.5 effects. RESULTS: We followed more than 19 million subjects and observed more than 6 million deaths. We found a harmful impact of annual PM2.5 concentrations on survival (hazard ratio = 1.11 [95% confidence interval = 1.01, 1.23] per 10 μg/m). This effect was modified by particulate composition, with higher effects observed in clusters containing high concentrations of nickel, vanadium, and sulfate. For instance, our highest effect estimate was observed in cities with harbors in the Northwest, characterized by high nickel, vanadium, and elemental carbon concentrations (1.9 [1.1, 3.3]). We observed null or negative associations in clusters with high oceanic and crustal particles. CONCLUSIONS: To the best of our knowledge, this is the first study to examine the association between PM2.5 composition and survival. Our findings indicate that long-term exposure to fuel oil combustion and power plant emissions have the highest impact on survival.

We investigated short-term changes in ambient air pollutant concentrations, including speciated particulate matter less than 2.5 μm in diameter (PM2.5), in relation to emergency department (ED) visits for respiratory infections in young children. Daily counts of ED visits for bronchitis and bronchiolitis (n = 80,399), pneumonia (n = 63,359), and upper respiratory infection (URI) (n = 359,246) among children 0-4 years of age were collected from hospitals in the Atlanta, Georgia, area for the period 1993-2010. Daily pollutant measurements were combined across monitoring stations using population weighting. In Poisson generalized linear models, 3-day moving average concentrations of ozone, nitrogen dioxide, and the organic carbon fraction of particulate matter less than 2.5 μm in diameter (PM2.5) were associated with ED visits for pneumonia and URI. Ozone associations were strongest and were observed at low (cold-season) concentrations; a 1-interquartile range increase predicted a 4% increase (95% confidence interval: 2%, 6%) in visits for URI and an 8% increase (95% confidence interval: 4%, 13%) in visits for pneumonia. Rate ratios tended to be higher in the 1- to 4-year age group compared with infants. Results suggest that primary traffic pollutants, ozone, and the organic carbon fraction of PM2.5 exacerbate upper and lower respiratory infections in early life, and that the carbon fraction of PM2.5 is a particularly harmful component of the ambient particulate matter mixture.

Because much ambient PM is derived from combustion sources, we tested the hypothesis that the health effects of PM arise from anthropogenic PM that contains bioavailable transition metals. The PM samples studied derived from three emission sources (two oil and one coal fly ash) and four ambient airsheds (St. Louis, MO; Washington; Dusseldorf, Germany; and Ottawa, Canada). PM was administered to rats by intratracheal instillation in equimass or equimetal doses to address directly the influence of PM mass versus metal content on acute lung injury and inflammation. Our results indicated that the lung dose of bioavailable transition metal, not instilled PM mass, was the primary determinant of the acute inflammatory response for both the combustion source and ambient PM samples. Residual oil fly ash, a combustion PM rich in bioavailable metal, was evaluated in a rat model of cardiopulmonary disease (pulmonary vasculitis/hypertension) to ascertain whether the disease state augmented sensitivity to that PM. Significant mortality and enhanced airway responsiveness were observed. Analysis of the lavaged lung fluids suggested that the milieu of the inflamed lung amplified metal-mediated oxidant chemistry to jeopardize the compromised cardiopulmonary system. We propose that soluble metals from PM mediate the array of PM-associated injuries to the cardiopulmonary system of the healthy and at-risk compromised host.

(U. S. Department of Health and Human Services, Public Health Services)Dozens of studies link acute exposure to particulate matter (PM) air pollution with premature mortality and morbidity, but questions remain about which species and sources in the vast PM mixt. are responsible for the obsd. health effects. Although a few studies exist on the effects of species and sources in U.S. cities, European cities-which have a higher proportion of diesel engines and denser urban populations-have not been well characterized. Information on the effects of specific sources could aid in targeting pollution control and in articulating the biol. mechanisms of PM. Our study examd. the effects of various PM sources on daily mortality for 2003 through 2007 in Barcelona, a densely populated city in the northeast corner of Spain. Source apportionment for PM ≤ 2.5 μm and ≤ 10 μm in aerodynamic diam. (PM2.5 and PM10) using pos. matrix factorization identified eight different factors. Case-crossover regression anal. was used to est. the effects of each factor. Several sources of PM2.5, including vehicle exhaust, fuel oil combustion, secondary nitrate/orgs., minerals, secondary sulfate/orgs., and road dust, had statistically significant assocns. (p < 0.05) with all-cause and cardiovascular mortality. Also, in some cases relative risks for a resp. interquartile range increase in concn. were higher for specific sources than for total PM2.5 mass. These results along with those from our multisource models suggest that traffic, sulfate from shipping and long-range transport, and construction dust are important contributors to the adverse health effects linked to PM.

[PM with aerodynamic diams. ≤ 10 μm (PM10) or ≤ 2.5 μm (PM2.5)] as a metric. It has been suggested that particles from combustion sources are more relevant to human health than are particles from other sources, but the impact of policies directed at reducing PM from combustion processes is usually relatively small when effects are estd. for a redn. in the total mass concn. We evaluated the value of black carbon particles (BCP) as an addnl. indicator in air quality management. We performed a systematic review and meta-anal. of health effects of BCP compared with PM mass based on data from time-series studies and cohort studies that measured both exposures. We compared the potential health benefits of a hypothetical traffic abatement measure, using near-roadway concn. increments of BCP and PM2.5 based on data from prior studies. Estd. health effects of a 1-μg/m3 increase in exposure were greater for BCP than for PM10 or PM2.5, but estd. effects of an interquartile range increase were similar. Two-pollutant models in time-series studies suggested that the effect of BCP was more robust than the effect of PM mass. The estd. increase in life expectancy assocd. with a hypothetical traffic abatement measure was four to nine times higher when expressed in BCP compared with an equiv. change in PM2.5 mass. BCP is a valuable addnl. air quality indicator to evaluate the health risks of air quality dominated by primary combustion particles.

(BioMed Central Ltd.)Background: The involvement of particulate matter (PM) in cardiorespiratory diseases is now established in developed countries whereas in developing areas such as Africa with a high level of specific pollution, PM pollution and its effects are poorly studied. Our objective was to characterize the biol. reactivity of urban African aerosols on human bronchial epithelial cells in relation to PM physico-chem. properties to identify toxic sources. Methods: Size-speciated aerosol chem. compn. was analyzed in Bamako (BK, Mali, 2 samples with one having desert dust event BK1) and Dakar (DK; Senegal) for Ultrafine UF, Fine F and Coarse C PM. PM reactivity was studied in human bronchial epithelial cells investigating six biomarkers (oxidative stress responsive genes and proinflammatory cytokines). Results: PM mass concns. were mainly distributed in coarse mode (60%) and were impressive in BK1 due to the desert dust event. BK2 and DK samples showed a high content of total carbon characteristic of urban areas. The DK sample had huge PAH quantities in bulk aerosol compared with BK that had more water sol. org. carbon and metals. Whatever the site, UF and F PM triggered the mRNA expression of the different biomarkers whereas coarse PM had little or no effect. The GM-CSF biomarker was the most discriminating and showed the strongest pro-inflammatory effect of BK2 PM. The anal. of gene expression signature and of their correlation with main PM compds. revealed that PM-induced responses are mainly related to org. compds. The toxicity of African aerosols is carried by the finest PM as with Parisian aerosols, but when considering PM mass concns., the African population is more highly exposed to toxic particulate pollution than French population. Regarding the prevailing sources in each site, aerosol biol. impacts are higher for incomplete combustion sources resulting from two-wheel vehicles and domestic fires than from diesel vehicles (Dakar). Desert dust events seem to produce fewer biol. impacts than anthropogenic sources. Discussion: Our study shows that combustion sources contribute to the high toxicity of F and UF PM of African urban aerosols, and underlines the importance of emission mitigation and the imperative need to evaluate and to regulate particulate pollution in Africa.

(Elsevier Ltd.)A review. It has been hypothesized that the compn. of particulate matter (PM) may be a better predictor of health effects than PM mass alone. The regional differences in PM compn. and the heterogeneity in PM risk ests. in large multi-city epidemiol. studies are consistent with this hypothesis. Since 2005, efforts have been made to relate apportioned components and sources of PM with human health outcomes in epidemiol., controlled human exposure and toxicol. studies. We reviewed published studies that: (1) focused on short-term exposure to PM; (2) included at least five components of PM; (3) grouped them into factors or sources; and (4) used quant. methods to examine the relationship between the factors or sources and health effects. Examn. includes to det. if specific groups of PM components or sources of PM are consistently linked to specific health effects across studies. The studies suggest that cardiovascular effects may be assocd. with PM2.5 from crustal or combustion sources, including traffic, but at this time, no consistent relationships have emerged. Fewer studies evaluated respiratory health effects, and the evidence for assocns. was limited. Apportionment methods have linked a variety of health effects to multiple groups of PM components and sources of PM, but the collective evidence has not yet isolated factors or sources that would be closely and unequivocally related to specific health outcomes.

A LUR for year 2006 ground-level NO2 concns. throughout contiguous US is discussed. The approach used ground- and satellite-based NO2 measurements, and geog. characteristics (population d., land use [satellite-based data], distance to major and minor roads). Results provided reliable ests. of ambient NO2 air pollution measured by USEPA (R2 = 0.78; bias = 22%) at a spatial resoln. (∼30 m) capable of capturing within-urban and near-roadway NO2 gradients. Several aspects of temporal (time-of-day, day-of-week, season) and spatial (urban vs. rural; US region) variability in the model. Results were robust to spatial auto-correlation, to selection of an alternative input dataset, and to minor perturbations in input data (using 90% of the data to predict the remaining 10%). Modeled population-weighted (unweighted) mean outdoor concns. in the US was 10.7 (4.8) ppb. This approach could be implemented in other world areas given sufficient road network and pollutant monitoring data. To facilitate future use and evaluation of results, concn. ests. for the ∼8 million census blocks in the contiguous US are publicly available via the supporting information.

Several studies have analyzed the ancillary impacts of GHG policies for a variety of locations, pollutants, and policies. In this paper we review the existing evidence on ancillary health benefits relating to air pollution from various GHG strategies and provide a framework for such analysis. METHODS: We evaluate techniques used in different stages of such research for estimation of: (1) changes in air pollutant concentrations; (2) avoided adverse health endpoints; and (3) economic valuation of health consequences. The limitations and merits of various methods are examined. Finally, we conclude with recommendations for ancillary benefits analysis and related research gaps in the relevant disciplines. RESULTS: We found that to date most assessments have focused their analysis more heavily on one aspect of the framework (e.g., economic analysis). While a wide range of methods was applied to various policies and regions, results from multiple studies provide strong evidence that the short-term public health and economic benefits of ancillary benefits related to GHG mitigation strategies are substantial. Further, results of these analyses are likely to be underestimates because there are a number of important unquantified health and economic endpoints. CONCLUSION: Remaining challenges include integrating the understanding of the relative toxicity of particulate matter by components or sources, developing better estimates of public health and environmental impacts on selected sub-populations, and devising new methods for evaluating heretofore unquantified and non-monetized benefits.

(Nature Publishing Group)Actions to reduce greenhouse gas (GHG) emissions often reduce co-emitted air pollutants, bringing co-benefits for air quality and human health. Past studies typically evaluated near-term and local co-benefits, neglecting the long-range transport of air pollutants, long-term demog. changes, and the influence of climate change on air quality. Here we simulate the co-benefits of global GHG redns. on air quality and human health using a global atm. model and consistent future scenarios, via two mechanisms: reducing co-emitted air pollutants, and slowing climate change and its effect on air quality. We use new relationships between chronic mortality and exposure to fine particulate matter and ozone, global modeling methods and new future scenarios. Relative to a ref. scenario, global GHG mitigation avoids 0.5±0.2, 1.3±0.5 and 2.2±0.8 million premature deaths in 2030, 2050 and 2100. Global av. marginal co-benefits of avoided mortality are US$50-380 per tonne of CO2, which exceed previous ests., exceed marginal abatement costs in 2030 and 2050, and are within the low range of costs in 2100. East Asian co-benefits are 10-70 times the marginal cost in 2030. Air quality and health co-benefits, esp. as they are mainly local and near-term, provide strong addnl. motivation for transitioning to a low-carbon future.

(American Association for the Advancement of Science)Tropospheric ozone and black carbon (BC) contribute to both degraded air quality and global warming. We considered ~400 emission control measures to reduce these pollutants by using current technol. and experience. We identified 14 measures targeting methane and BC emissions that reduce projected global mean warming ~0.5°C by 2050. This strategy avoids 0.7 to 4.7 million annual premature deaths from outdoor air pollution and increases annual crop yields by 30 to 135 million metric tons due to ozone redns. in 2030 and beyond. Benefits of methane emissions redns. are valued at 700 to 5000 per metric ton, which is well above typical marginal abatement costs (less than 250). The selected controls target different sources and influence climate on shorter time scales than those of carbon dioxide-redn. measures. Implementing both substantially reduces the risks of crossing the 2°C threshold.

(American Chemical Society)The implicit assumption that biogenic secondary org. aerosol (SOA) is natural and cannot be controlled hinders effective air quality management. Anthropogenic pollution facilitates transformation of naturally-emitted volatile org. compds. (VOC) to the particle phase, enhancing ambient biogenic SOA concns. Thus, it is conceivable a portion of ambient biogenic SOA can be removed by controlling anthropogenic pollutant emissions. Direct measurement of the controllable fraction of biogenic SOA is not possible, but can be estd. using 3-dimensional photochem. air quality modeling. To examine this, 22 Community Multi-scale Air Quality model simulations were conducted over the continental US. Relative contributions of 5 emitted pollution classes (NOx, NH3, SOx, reactive non-methane C, primary carbonaceous particulate matter) on biogenic SOA were estd. by removing anthropogenic emissions of these pollutants, one at a time then all together. Model results demonstrated a strong effect of anthropogenic emissions on predicted biogenic SOA concns., suggesting >50% of biogenic SOA in the eastern US can be controlled. Since biogenic SOA is substantially enhanced by controllable emissions, classifying SOA as biogenic or anthropogenic based solely on VOC origin is not sufficient to describe the controllable fraction.

(Copernicus Publications)The literature on atm. particulate matter (PM), or atm. aerosol, has increased enormously over the last 2 decades and amts. now to some 1500-2000 papers per yr in the refereed literature. This is in part due to the enormous advances in measurement technologies, which have allowed for an increasingly accurate understanding of the chem. compn. and of the phys. properties of atm. particles and of their processes in the atm. The growing scientific interest in atm. aerosol particles is due to their high importance for environmental policy. In fact, particulate matter constitutes one of the most challenging problems both for air quality and for climate change policies. In this context, this paper reviews the most recent results within the atm. aerosol sciences and the policy needs, which have driven much of the increase in monitoring and mechanistic research over the last 2 decades. The synthesis reveals many new processes and developments in the science underpinning climate-aerosol interactions and effects of PM on human health and the environment. However, while airborne particulate matter is responsible for globally important influences on premature human mortality, we still do not know the relative importance of the different chem. components of PM for these effects. Likewise, the magnitude of the overall effects of PM on climate remains highly uncertain. Despite the uncertainty there are many things that could be done to mitigate local and global problems of atm. PM. Recent analyses have shown that reducing black carbon (BC) emissions, using known control measures, would reduce global warming and delay the time when anthropogenic effects on global temp. would exceed 2 °C. Likewise, cost-effective control measures on ammonia, an important agricultural precursor gas for secondary inorg. aerosols (SIA), would reduce regional eutrophication and PM concns. in large areas of Europe, China and the USA. Thus, there is much that could be done to reduce the effects of atm. PM on the climate and the health of the environment and the human population. A prioritized list of actions to mitigate the full range of effects of PM is currently undeliverable due to shortcomings in the knowledge of aerosol science; among the shortcomings, the roles of PM in global climate and the relative roles of different PM precursor sources and their response to climate and land use change over the remaining decades of this century are prominent. In any case, the evidence from this paper strongly advocates for an integrated approach to air quality and climate policies.

(U. S. Department of Health and Human Services, National Institutes of Health)Background: Assocns. between airborne particles and health outcomes have been documented worldwide; however, there is limited information regarding health effects assocd. with different particle sizes. Objectives: We explored the assocn. between size-fractionated particle no. concns. (PNCs) and daily mortality in Shenyang, China. Methods: We collected daily data on cause-specific mortality and PNCs for particles measuring 0.25-10 μm in diam. between 1 Dec. 2006 and 30 Nov. 2008. We used Quasi-Poisson regression generalized additive models to est. assocns. between PNCs and mortality, and we used natural spline smoothing functions to adjust for time-varying covariates and long-term and seasonal trends. Results: Mean nos. of daily deaths were 67, 32 and 7 for all natural causes, cardiovascular diseases, and respiratory diseases, resp. Interquartile range (IQR) increases in PNCs for particles measuring 0.25-0.50 μm were significantly assocd. with total and cardiovascular mortality, but not respiratory mortality. Effect ests. were larger for PNCs during the warm season than the cool season, and increased with decreasing particle size. IQR increases in PNCs of 0.25-0.28 μm, 0.35-0.40 μm, and 0.45-0.50 μm particles were assocd. with 2.41% (95% CI: 1.23, 3.58 %), 1.31% (95% CI: 0.52, 2.09 %), and 0.45% (95% CI: 0.04, 0.87 %) higher total mortality, resp. Assocns. were generally stable after adjustment for mass concns. of ambient particles and gaseous pollutants. Conclusions: Our findings suggest that particles <0.5 μm in diam. may be most responsible for adverse health effects of particulate air pollution and that adverse health effects may increase with decreasing particle size.

(Elsevier)Air quality modeling could potentially improve exposure ests. for use in epidemiol. studies. We investigated this application of air quality modeling by estg. location-specific (point) and spatially-aggregated (county level) exposure concns. of particulate matter with an aerodynamic diam. less than or equal to 2.5 μm (PM2.5) and ozone (O3) for the eastern U.S. in 2002 using the community multi-scale air quality (CMAQ) modeling system and a traditional approach using ambient monitors. The monitoring approach produced ests. for 370 and 454 counties for PM2.5 and O3, resp. Modeled ests. included 1861 counties, covering 50% more population. The population uncovered by monitors differed from those near monitors (e.g., urbanicity, race, education, age, unemployment, income, modeled pollutant levels). CMAQ overestimated O3 (annual normalized mean bias=4.30%), while modeled PM2.5 had an annual normalized mean bias of -2.09%, although bias varied seasonally, from 32% in Nov. to -27% in July. Epidemiol. may benefit from air quality modeling, with improved spatial and temporal resoln. and the ability to study populations far from monitors that may differ from those near monitors. However, model performance varied by measure of performance, season, and location. Thus, the appropriateness of using such modeled exposures in health studies depends on the pollutant and metric of concern, acceptable level of uncertainty, population of interest, study design, and other factors.

(2013), 24 (4), 555-61 ISSN:.BACKGROUND: Many studies have reported associations between ambient particulate matter (PM) and adverse health effects, focused on either short-term (acute) or long-term (chronic) PM exposures. For chronic effects, the studied cohorts have rarely been representative of the population. We present a novel exposure model combining satellite aerosol optical depth and land-use data to investigate both the long- and short-term effects of PM2.5 exposures on population mortality in Massachusetts, United States, for the years 2000-2008. METHODS: All deaths were geocoded. We performed two separate analyses: a time-series analysis (for short-term exposure) where counts in each geographic grid cell were regressed against cell-specific short-term PM2.5 exposure, temperature, socioeconomic data, lung cancer rates (as a surrogate for smoking), and a spline of time (to control for season and trends). In addition, for long-term exposure, we performed a relative incidence analysis using two long-term exposure metrics: regional 10 × 10 km PM2.5 predictions and local deviations from the cell average based on land use within 50 m of the residence. We tested whether these predicted the proportion of deaths from PM-related causes (cardiovascular and respiratory diseases). RESULTS: For short-term exposure, we found that for every 10-μg/m increase in PM 2.5 exposure there was a 2.8% increase in PM-related mortality (95% confidence interval [CI] = 2.0-3.5). For the long-term exposure at the grid cell level, we found an odds ratio (OR) for every 10-μg/m increase in long-term PM2.5 exposure of 1.6 (CI = 1.5-1.8) for particle-related diseases. Local PM2.5 had an OR of 1.4 (CI = 1.3-1.5), which was independent of and additive to the grid cell effect. CONCLUSIONS: We have developed a novel PM2.5 exposure model based on remote sensing data to assess both short- and long-term human exposures. Our approach allows us to gain spatial resolution in acute effects and an assessment of long-term effects in the entire population rather than a selective sample from urban locations.

(2005), 16 (6), 727-36 ISSN:1044-3983.BACKGROUND: The assessment of air pollution exposure using only community average concentrations may lead to measurement error that lowers estimates of the health burden attributable to poor air quality. To test this hypothesis, we modeled the association between air pollution and mortality using small-area exposure measures in Los Angeles, California. METHODS: Data on 22,905 subjects were extracted from the American Cancer Society cohort for the period 1982-2000 (5,856 deaths). Pollution exposures were interpolated from 23 fine particle (PM2.5) and 42 ozone (O3) fixed-site monitors. Proximity to expressways was tested as a measure of traffic pollution. We assessed associations in standard and spatial multilevel Cox regression models. RESULTS: After controlling for 44 individual covariates, all-cause mortality had a relative risk (RR) of 1.17 (95% confidence interval=1.05-1.30) for an increase of 10 mug/m PM2.5 and a RR of 1.11 (0.99-1.25) with maximal control for both individual and contextual confounders. The RRs for mortality resulting from ischemic heart disease and lung cancer deaths were elevated, in the range of 1.24-1.6, depending on the model used. These PM results were robust to adjustments for O3 and expressway exposure. CONCLUSION: Our results suggest the chronic health effects associated with within-city gradients in exposure to PM2.5 may be even larger than previously reported across metropolitan areas. We observed effects nearly 3 times greater than in models relying on comparisons between communities. We also found specificity in cause of death, with PM2.5 associated more strongly with ischemic heart disease than with cardiopulmonary or all-cause mortality.

(U. S. Department of Health and Human Services, National Institutes of Health)BACKGROUND: Approx. 2.8 billion people cook with solid fuels. Research has focused on the health impacts of indoor exposure to fine particulate pollution. Here, for the 2010 Global Burden of Disease project (GBD 2010), we evaluated the impact of household cooking with solid fuels on regional population-weighted ambient PM2.5 (particulate matter ≤ 2.5 μm) pollution (APM2.5). OBJECTIVES: We estd. the proportion and concns. of APM2.5 attributable to household cooking with solid fuels (PM2.5-cook) for the years 1990, 2005, and 2010 in 170 countries, and assocd. ill health. METHODS: We used an energy supply-driven emissions model (GAINS; Greenhouse Gas and Air Pollution Interactions and Synergies) and source-receptor model (TM5-FASST) to est. the proportion of APM2.5 produced by households and the proportion of household PM2.5 emissions from cooking with solid fuels. We estd. health effects using GBD 2010 data on ill health from APM2.5 exposure. RESULTS: In 2010, household cooking with solid fuels accounted for 12% of APM2.5 globally, varying from 0% of APM2.5 in five higher-income regions to 37% (2.8 μg/m3 of 6.9 μg/m3 total) in southern sub-Saharan Africa. PM2.5-cook constituted > 10% of APM2.5 in seven regions housing 4.4 billion people. South Asia showed the highest regional concn. of APM2.5 from household cooking (8.6 μg/m3). On the basis of GBD 2010, we est. that exposure to APM2.5 from cooking with solid fuels caused the loss of 370,000 lives and 9.9 million disability-adjusted life years globally in 2010. CONCLUSIONS: PM2.5 emissions from household cooking constitute an important portion of APM3.5 concns. in many places, including India and China. Efforts to improve ambient air quality will be hindered if household cooking conditions are not addressed.

(Nature Publishing Group)Assessing the global burden of disease is based on epidemiol. cohort studies which connect premature mortality to a wide range of causes, including long-term health impacts of O3 and fine particulate matter (PM2.5). It is difficult to quantify premature mortality related to air pollution, notably in regions where air quality is not monitored, and because toxicity of particles from various sources may vary. This work used a global atm. chem. model to assess the link between premature mortality and 7 emission source categories in urban and rural environments. In accord with the global burden of disease for 2010 (S.S. Lim, et al., 2013), the authors calcd. outdoor air pollution, mostly PM2.5, led to 3.3 million (95% confidence interval, 1.61-4.81) premature deaths/yr worldwide, predominantly in Asia. It was primarily assumed that all particles were equally toxic, but a sensitivity study was conducted to account for differential toxicity. Results showed emissions from residential energy use (heating, cooking), prevalent in India and China, had the largest effect on premature mortality globally, even more dominant if carbonaceous particles are assumed to be most toxic. In much of the US and several other countries, traffic and power generation emissions are important. In eastern US, Europe, Russia, and East Asia, agricultural emissions provide the largest relative contribution to PM2.5, with estd. overall health impact dependent on particle toxicity assumptions. Model projections based on a business-as-usual emission scenario indicated the contribution of outdoor air pollution to premature mortality could double by 2050.
