A total of 10 surface soil samples covering the whole territory of Linfen city were collected for analysis the 144 polychlorinated biphenyls (PCBs). The total PCBs concentration ranged from 0.2 to 3.4 ng g(-1) in urban soil and 0.5 to 14.8 ng g(-1) in industrial plant soil. Furthermore, increasing PCBs contamination was observed in northeast Linfen because of the distribution of industrial plants. Principal component analysis (PCA) revealed that the major source of PCBs in Linfen may be potentially associated with commercial #1 PCB through the long-range transmission. In total, PCBs were not a severe contamination in Linfen from current results.
共采集了覆盖临汾市全境的10个表层土壤样本，用于分析144种多氯联苯（PCBs）。城市土壤中多氯联苯的总浓度范围为0.2至3.4纳克/克，工业厂区土壤中为0.5至14.8纳克/克。此外，由于工业厂区的分布，临汾东北部的多氯联苯污染呈上升趋势。主成分分析（PCA）表明，临汾多氯联苯的主要来源可能与商业#1多氯联苯通过长距离传输潜在相关。从目前的结果来看，总体而言，多氯联苯在临汾并非严重污染物。
