|Abstract:||Atmospheric concentrations of polycyclic aromatic hydrocarbons (PAHs) were measured at urban/industrial, suburban, coastal, and rural areas in New Jersey as part of the New Jersey Atmospheric Deposition Network. Concentrations of 36 PAH compounds were measured in the gas and particle phases in air and in precipitation at nine sites at regular intervals from October 1997 through May 2001. Gas-phase and particle-phase SUM 36PAH concentrations ranged from 0.45 to 118 ng/m3 and from 0.046 to 172 ng/m3, respectively, and precipitation concentrations ranged from 11 to 16200 ng/L. PAH concentrations vary spatially across the region, with the highest concentrations occurring at the most heavily urban and industrial locations. Average gas absorption deposition ranged from 0.004 (naphthacene) to 5040 (methylphenanthrenes) ng/m2 d, and dry particle deposition PAH fluxes ranged from 0.11 (naphthacene) to 300 (benzo[b+k]fluoranthene) ng/m2 d at the nine sites. Average atmospheric wet deposition PAH fluxes at the seven sites ranged from 0.40 (cyclopenta-[cd]pyrene) to 140 (methylphenanthrenes) ng/m2 d. These represent the first comprehensive estimates of PAH deposition to New Jersey and the Mid-Atlantic East Coast.|
