摘　　要：多氯联苯(PCBs)是一种具有亲脂性、低水溶性、高稳定性和高生物富集性等特性的持久性有机污染物(POPs),而沉积物作为疏水性有机污染物(HOCs)的重要地质宿体,PCBs在POPs中发生的环境过程是研究的热点。本文综述国内外近几年来沉积物中PCBs分析测定以及迁移转化的研究动态,并对今后PCBs污染的生物修复研究提出了自己的见解。Polychlorinated biphenyls（PCBs）are a group of persistent organic pollutants（POPs） with properties of lipophilicity,low water-solubility,high stability and bioaccumulation.The environmental process of PCBs occurred in the sediment,which is an important geological sink for the hydrophobic organic pollutants（HOCs）,is the hot subject associated with the POPs research.This study has comprehensively reviewed the research progresses on the analysis,migration and transformation of PCBs in sediments,introduced some new achievements of the research on the migration and transformation of PCBs in sediments.Finally,this study has proposed some own points for the research on the Bioremediation of PCBs in future. polychlorinated biphenyls
