Abstract

Polychlorinated biphenyls (PCBs) have been detected in a variety of environmental media, and they have been continuously introduced into the environment for industrial reasons, despite their harmful impact upon ecological health. Considering the adverse effects of PCBs, many researchers have begun to analyze remediation technologies for PCB-contaminated soil. In this study, the rise and fall of PCBs, as well as their physical and chemical properties and environmental impact, were reviewed. The pollution status of PCBs in soil was summarized. Based on the analysis and comparison of various remediation technologies, the limitations of several phytoremediation technologies in PCB-contaminated soils were analyzed. The influencing factors and transformation mechanisms of the phytoremediation of PCB-contaminated soil were investigated, and the research direction of enhancing the degradation of PCBs through the use of plants was also discussed.
