Abstract
A literature review of the atmospheric chemistry of eight potentially toxic air contaminants was carried out: chloroform, 1,3-butadiene, benzo(a)pyrene (BaP; a polycyclic aromatic hydrocarbon or PAH), formaldehyde, acetaldehyde, ethylene oxide, styrene, and diesel exhaust particles (including gas- and particle-phase PAHs and derivatives). Experimental studies were carried out on styrene (reaction with nitrate radical and ozone), 1,4-dioxane (reaction with ozone), nitrobenzene (reaction with ozone), and p-dichlorobenzene (reaction with nitrate radical and ozone). These data were obtained by the California Air Resources Board for incorporation into reports on exposure assessments for these compounds, which is required as part of the process of identifying and controlling toxic air contaminants. Also investigated were ring-retaining products formed from the hydroxyl radical reactions (in the presence of nitrogen oxides) with benzene, toluene, and the three xylene isomers.
