Exposure to ambient polycyclic aromatic hydrocarbons (PAHs) is a potential health concern for communities because many PAHs are known to be mutagenic and carcinogenic. However, information on ambient concentrations of PAHs in communities is very limited. During the Urban Community Air Toxics Monitoring Project, Paterson City, NJ, PAH concentrations in ambient air PM10 (particulate matter < or = 10 microm in aerodynamic diameter) were measured from November 2005 through December 2006 in Paterson, a mixed-use urban community located in Passaic County, NJ. Three locations dominated by industrial, commercial, and mobile sources were chosen as monitoring sites. The comparison background site was located in Chester, NJ, which is approximately 58 km west/southwest of Paterson. The concentrations of all of the individual PAHs at all three Paterson sites were found to be significantly higher than those at the background site (P < 0.05). The PAH profiles obtained from the three sites with different land-use patterns showed that the contributions of heavier PAHs (molecular weight > 202) to the total PAHs were significantly higher at the industrial site than those at the commercial and mobile sites. Analysis of the diagnostic ratios between PAH isomers suggested that the diesel-powered vehicles were the major PAH sources in the Paterson area throughout the year. The operation of industrial facilities and other combustion sources also partially contributed to PAH air pollution in Paterson. The correlation of individual PAH, total PAH, and the correlation of total PAHs with other air co-pollutants (copper, iron, manganese, lead, zinc, elemental carbon, and organic carbon) within and between the sampling sites supported the conclusions obtained from the diagnostic ratio analysis.
暴露于环境多环芳烃（PAHs）是社区潜在的健康问题，因为许多 PAHs 已知具有致突变性和致癌性。然而，关于社区环境中 PAHs 浓度的信息非常有限。在城市社区空气有毒物质监测项目中，新泽西州帕特森市于 2005 年 11 月至 2006 年 12 月期间测量了大气 PM10（空气动力学直径小于或等于 10 微米的颗粒物）中的 PAH 浓度，帕特森是一个位于新泽西南部帕塞伊克县的混合用途城市社区。选择了三个以工业、商业和移动源为主的地点作为监测点。比较背景点位于新泽西州切斯特，距帕特森市西南偏西约 58 公里。所有三个帕特森地点的所有单个 PAH 浓度都明显高于背景地点（P<0.05）。从三个具有不同土地利用模式的地点获得的 PAH 分布表明，在工业地点，较重 PAH（分子量>202）对总 PAH 的贡献明显高于商业和移动地点。对 PAH 异构体之间的诊断比值的分析表明，全年柴油机车辆是帕特森地区 PAH 的主要来源。工业设施的运行和其他燃烧源也部分导致了帕特森的 PAH 空气污染。单个 PAH、总 PAH 以及总 PAH 与其他空气共污染物（铜、铁、锰、铅、锌、元素碳和有机碳）之间和之间的采样点之间的相关性支持了从诊断比分析得出的结论。
