Remediation Technologies of PCBs-Contaminated Soil
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.
