Analyzing the ignored enviromental contaminants • 140A
Just about all household chemicals on the market, from pharmaceuticals and hormones to detergents and disinfectants, have, in one form or another, found their way into aquatic environments. Britt E. Erickson examines how little is known about these emerging organic contaminants, in terms of their toxicity and behavior in the environment, and how U.S. and European risk-assessment attitudes differ. She considers what it takes to become a targeted wastewater pollutant, pointing out that if history is any indication, it has a lot to do with the availability of analytical methods and reference standards. |

Perfluorochemical surfactants in the environments • 146A
Concern is growing about fluorinated organic compounds, which are globally distributed, environmentally persistent, bioaccumulative, and potentially harmful. Little is known about how fully fluorinated compounds are transported in air, and methods are needed for understanding their movement into remote regions, say John Giesy and Kurunthachalam Kannan. They discuss current knowledge about these compounds and future research needs. |

Magnetic resonance imaging in environmental science • 154A
Advances in magnetic resonance imaging (MRI) equipment and techniques are creating opportunities for applications in the environmental sciences that will help researchers better understand subsurface phenomena. Focusing on subsurface processes such as the transport and dynamics of water, dissolved materials, and nonaqueous-phase liquids in soils and sediments, Nikolaus Nestle, Thomas Baumann, and Reinhard Niessner explore MRI applications in environmental science. |
