Outdoor air polychlorinated biphenyl (PCB) concentrations were measured in upstate New York as part of a nonoccupational exposure investigation. The adjacent study communities of Hudson Falls and Fort Edward contain numerous sites of current and former PCB contamination, including two capacitor-manufacturing facilities. Outdoor air PCB concentrations in the study municipalities were significantly higher than in the comparison municipality of Glens Falls. Total PCB concentrations in the study area ranged from 0.102 to 4.011 ng/m(3) (median: 0.711 ng/m(3)). For the comparison area, concentrations ranged from 0.080 to 2.366 ng/m(3) (median: 0.431 ng/m(3)). Although our sampling was not designed to identify point sources, the presence of PCB-contaminated sites in the study area likely contributed to this observed difference in concentration. While elevated relative to the comparison area, total PCB concentrations in the study area are lower than those in other communities with known PCB-contaminated sites, and similar to levels reported in other locations from the northeastern United States.
作为一项非职业性暴露调查的一部分，在纽约州北部对室外空气中多氯联苯（PCB）的浓度进行了测量。哈德逊福尔斯和爱德华堡这两个相邻的研究社区包含许多当前和以前受多氯联苯污染的场地，其中包括两家电容器制造工厂。研究城市的室外空气中多氯联苯浓度显著高于对照城市格伦斯福尔斯。研究区域内多氯联苯的总浓度范围为0.102至4.011纳克/立方米（中位数：0.711纳克/立方米）。对照区域的浓度范围为0.080至2.366纳克/立方米（中位数：0.431纳克/立方米）。尽管我们的采样并非旨在识别点源，但研究区域内存在受多氯联苯污染的场地可能是造成观察到的浓度差异的原因。虽然相对于对照区域有所升高，但研究区域内多氯联苯的总浓度低于其他已知有多氯联苯污染场地的社区，并且与美国东北部其他地区报告的水平相似。
