Particulate and gas-phase mutagens in ambient and simulated atmospheres. Final report
Technical Report

OSTI ID:6073141
Ambient POM samples were collected concurrently at two sites in California's South Coast Air Basin (El Monte and Riverside), and analyzed for both chemical composition and mutagenic activity with the Ames Salmonella typhimurium bacterial assay. 2-Nitrofluoranthene and 2-nitropyrene were detected and quantified in ambient POM. The transformation of selected polycyclic aromatic hydrocarbons (PAH) absorbed on glass fiber (GF)and Teflon-impregnated glass fiber (TIGF) filters were also investigated under ambient conditions. Simultaneously, the ambient concentrations of a wide range of gaseous co-pollutants, which may participate in the atmospheric transformation and formation of ambient mutagens were characterized. UV/visible differential optical absorption spectroscopy (DOAS) was used to determine the ambient concentrations of HONO, NO/sub 3/ radicals, HCHO, NO/sub 2/ and SO/sub 2/. Nighttime concentrations of dinitrogen pentoxide (N/sub 2/O/sub 5/) were calculated. The formation of nitrous acid (HONO) from the hydrolysis of NO/sub 2/ was studied in an indoor environment, using a DOAS system especially modified and developed.
