The formation of photochemical organic aerosols from hydrocarbon precursors has been investigated in experiments performed in a large outdoor smog chamber and involving sunlight irradiation of ppm levels of olefinic hydrocarbons and nitrogen oxides in ambient air. Cyclohexene, cyclopentene, and 1,7-octadiene produced large amounts of organic aerosols (5 to 39% of the initial olefin concentration on a carbon basis), with aerosol production rates ranging from 1.5 to 40.6 micrograms C per cu m per min. Products identified by mass spectrometry included dicarboxylic acids and other alpha, omega-difunctional oxygenates bearing carboxylic, aldehyde, hydroxyl, or nitrate ester groups. The formation of these products is accounted for in terms of olefin-ozone and olefin-hydroxyl radical reactions.
