Tree bark was used as the passive air sampler to evaluate polychlorinated biphenyl (PCB) and polybrominated diphenyl ether (PBDE) pollution and possible sources in Southern Jiangsu. The concentrations of PCBs and Σ7PBDEs were in the range of 0.58-5.19 ng/g dry weight (dw; mean 1.79 ng/g dw) and 17.9-243 pg/g dw (mean 74.7 pg/g dw), respectively. Tri-PCBs were the major PCB homologs, and technical PCB product Ar1242 was identified as the main source. BDE209 concentrations (4.29-456 ng/g dw) were relatively high, indicating that BDE209 pollution was serious in this region. The deca-BDE commercial mixture was the predominant commercial PBDE product used in this region. A good correlation was found between tree bark and polyurethane foam (PUF) disks in Σ6PCB monitoring, suggesting that both of them respond well to the gas-phase PCB monitoring.
树皮被用作被动空气采样器，以评估苏南地区多氯联苯（PCB）和多溴二苯醚（PBDE）的污染情况及可能来源。PCB和Σ7PBDE的浓度分别在0.58 - 5.19纳克/克干重（dw；平均1.79纳克/克dw）和17.9 - 243皮克/克dw（平均74.7皮克/克dw）范围内。三氯联苯是主要的PCB同系物，技术PCB产品Ar1242被确定为主要来源。BDE209浓度（4.29 - 456纳克/克dw）相对较高，表明该地区BDE209污染严重。十溴二苯醚商业混合物是该地区使用的主要商业PBDE产品。在Σ六氯联苯监测中，发现树皮与聚氨酯泡沫（PUF）盘之间具有良好的相关性，表明它们对气相PCB监测的响应都很好。
