Occurrence of Polycyclic Aromatic Hydrocarbons Associated with Coal-Tar Based Pavement Sealant Related PAHs in Urban Sediments in Maine

The dataset includes results from the analysis of sediments and solids collected from receptor sites receiving runoff from adjacent parking lots and other paved surfaces. Receptor sites include parking lot catch basins, retention ponds, drainage ditches, and storm-water discharge zones in streams and rivers. Samples were analyzed for percent moisture content and concentrations of 17 U.S. Environmental Protection Agency Priority Pollutant Polycyclic Aromatic Hydrocarbons (PAHs). Samples collected from parking lot sweepings (dust) also were analyzed for the same suite of 17 PAH compounds.

本数据集包含接收邻近停车场及其他铺装路面径流的受纳点位所采集沉积物与固体样品的分析结果。受纳点位涵盖停车场截污井、雨水滞留塘、排水沟渠，以及溪流与河流中的雨水排放区域。所有采集样品均开展了含水率检测，以及17种美国环境保护署优先管控污染物多环芳烃（Polycyclic Aromatic Hydrocarbons, PAHs）的浓度分析。此外，从停车场清扫收集的粉尘样品，也针对上述17种多环芳烃化合物组合完成了相同项目的检测分析。
