Measurements of NO/sub 2/, HONO, NO/sub 3/, NCHO, PAH, nitroarenes, and particulate mutagenic activities during the carbonaceous-species-methods comparison study. Final report, 9 July 1986-30 July 1987
The ambient concentrations of NO/sub 2/, HONO and HCHO were measured by long-pathlength differential optical absorption spectroscopy. Ambient concentrations of HNO/sub 3/, NH/sub 3/ and HCHO were measured by long-pathlength Fourier infrared-absorption spectroscopy. Significant concentrations of these pollutants were observed. Ambient air samples were analyzed for mutagenicity and gas- and particle-associated polycyclic aromatic hydrocarbons (PAH) and nitroarenes. The mutagen densities obtained were consistent with those measured previously in the South Coast Air Basin. The following PAH and nitroarenes were observed and quantified: naphthalene, 1- and 2-methylnaphthalene, biphenyl, acenaphthene, acenaphthylene, fluorene, phenanthrene, anthracene, dibenzothiophene, fluoranthene, pyrene, benz(a)anthracene, chrysene/triphenylene, benzo(a)pyrene, 1- and 2-nitronaphthalene, 3-nitrobiphenyl, 2-, 3- and 8-nitrofluoranthrene, and 1- and 2-nitropyrene.
