摘　　要：[目的]研究土壤多氯联苯迁移规律。[方法]以浙东沿海某典型固废拆解区为研究区,通过对2004和2008年土壤、水体中PCBs含量的对比和典型地区PCBs含量的分析,对研究区土壤PCBs迁移规律进行研究。[结果]受地形影响,在水动力作用下,土壤中的PCBs可以发生长距离的迁移,并在低洼处的土壤表层浓集。[结论]建立了PCBs迁移模式,并对土壤多氯联苯污染的治理提出了新思路。[Objective] To study migration law of polychlorinated biphenyls in soils.[Method]The content of polychlorinated biphenyls (PCBs) in water and soil were investigated and contrasted in a typical solid waste’s dumping and unpacking site of eastern Zhejiang in2004 and2008.And contents of PCBs in soils and sediment was discussed deeply in typical area.On this basis,the migration law of PCBs was studied.[Result]Thanks to the influence of terrain slope and the water system,PCBs could migrate for a long distance in the transverse direction,and it would be enriched in surface soil of lowland.[Conclusion] The mode of PCBs migration was established,and a new thought of PCBs polluted soil treatment was proposed.
