多氯联苯污染土壤修复技术研究进展

Remediation Technologies of PCBs-Contaminated Soil

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 environment, which are toxic, carcinogenic and mutagenic. For PCBs are hydrophobic and lipophilic, soil is its final destination 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 development was also presented.
