Abstract

Polycyclic aromatic hydrocarbons (PAH) have been analysed from inhalable airborne particulate matter collected at four New Jersey locations during four 6-week periods (Summer 1981, Winter 1982, Summer 1982 and Winter 1983). The sites included three urban locations (Newark, Elizabeth and Camden) and one rural site (Ringwood). The analytical methodology involved soxhlet extraction of preheated glassfiber filters with cyclohexane, thin-layer chromatography and ultimate analysis using reverse-phase highperformance liquid chromatography and ultraviolet and fluorescence detection. The quality assurance/quality control procedure is described. Discussions of differences in PAH levels between urban and rural sites as well as the summer/winter differences in concentrations rely upon consideration of sources as well as differences in PAH reactivities. Comparisons of PAH levels are also made between pollution episode and non-episode periods. In addition intra- and intersite correlations between PAHs as well as other pollutants are discussed. Profiles of PAH do not appear to differ significantly between the few sites during a given season. © 1985.
