The polycyclic aromatic hydrocarbons (PAH) benzo-(a)pyrene, perylene, and 1-nitropyrene deposited on glass and Teflon filters (0.05, 0.25, and 4.1 micrograms/sq cm, respectively) as well as on glass and Teflon filters loaded with fly ash, diesel exhaust, and ambient particles were exposed in the dark to pure humid air, 100 ppb of ozone, 100 ppb of SO2, 100 ppb of nitric acid free NO2, and particle-free ambient air. All exposures were conducted for 3 h at sampling face velocities equivalent to those typical of high volume sampling. Under these conditions, there was no evidence for chemical transformations of the PAH irrespective of filter type and substrate. The environmental implications of these results are discussed in the context of existing literature data concerning interactions of PAH and their nitro derivatives and pollutant gases, with emphasis on PAH nitration. 28 references.
