A Review on Remediation Technologies of PCBs from the Contaminated Soils or Sediments

Polychlorinated biphenyls, which are toxic, carcinogenic and mutagenic, are ubiquitous and persistent in environment. For PCBs are hydrophobic and lipophilic, soils or sediments are their final destinations in environment. Consequently, PCBs-contaminated soils or sediments are increasingly attracting more and more attention. In this paper, basic properties of PCBs and the situation of PCBs-contaminated soils or sediments were described. Remediation technologies of PCBs-contaminated soils or sediments inside and outside China were reviewed. This paper also presented the prospect of technology development.
