| Abstract |
Model aerosols were generated from individual hydrocarbon precursors and nitrogen oxides under simulated atmospheric conditions in a 17.3 cu m environmental chamber. Hydrocarbon precursors employed were toluene, alpha-pinene, and cyclohexene. Aerosols were collected on glass-fiber filters and organic matter was obtained by solvent extraction. Organic reaction products were fractionated into acid, neutral, and basic components, and were analyzed in detail by techniques including gas chromatography and gas chromatography combined with mass spectrometry. The study also included evaluation of techniques for selective derivatization of aerosol products. A variety of polyfunctional reaction products were identified. |
