多氯联苯污染土壤修复技术研究进展

摘要

多氯联苯是环境中广泛存在的一种持久性有机化合物，具有三致作用。多氯联苯具有疏水性和亲脂性，土壤是其在环境中的最终归宿，因此，多氯联苯污染土壤的修复越来越受到重视。简介了多氯联苯的基本性质、土壤环境中多氯联苯的污染现状，综述了国内外多氯联苯污染土壤修复技术的研究进展，并对其发展前景进行了展望。%Polychlorinated biphenyls (PCBs)are ubiquitous and persistent organic pollutants in environ-ment,which are toxic,carcinogenic and mutagenic.For PCBs are hydrophobic and lipophilic,soil is its final des-tination in environment.Hence,PCBs-contaminated soil is increasingly attaining more and more attention.In this paper,basic properties of PCBs and the situation of PCBs-contaminated soil were described.Remediation technologies of PCBs-contaminated soil were reviewed both at home and abroad.The prospect of technology de-velopment was also presented.
