Abstract

A demonstration that illustrates the formation of particulate matter from a biogenic source is described. Ozone is allowed to react with the terpenes present in an orange peel. Products formed from the ozone-terpene reaction condense to form aerosols that scatter light from a laser pointer source. This demonstration has been used for high school students as well as college-level students to explain the reactions of ozone in the troposphere, the formation of secondary particulate matter (gas-to-particle conversion mechanisms), and degradation of visibility.
