Variations in the summertime concentrations of selected polycyclic aromatic hydrocarbons (PAH) collected by using inhalable particulate samplers (IPM-D, < 15 pm) at four sites in New Jersey are presented and examined. The levels of PAH found in this study are consistent with other urban values reported in the literature. While day-to-day trends in PAH concentrations at the four sites were influenced by regional meteorology, it appears that local sources had the greatest influence on ambient levels. Comparison of selected PAH with IPM, EOM (extractable organic matter), and Sod2values at each site showed weak correlations. However, intersite and intrasite Spearman rank correlations among PAH were significant and suggest a common type of source emitter at the urban locations during the summer. The intersite correlations also reflect the proximity of the four sites.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
