“…In the United States, more than 300 sites have contained or still contain PCB pollution; in Europe, there are more than 242,000 sites of PCB pollution; in Canada, there are more than 100 PCB pollution sites. The contamination concentrations of PCBs in the soil of developed countries such as the United Kingdom and the United States has reached 50 mg/kg [24][25][26]. Due to improper disposal of waste transformer facilities and equipment in Nigeria, PCBs have leaked, causing great damage to local soil resources and water resources, affecting people's normal work and life [27].…”

“…The situation of PCB soil pollution in China is also not promising. It has been reported that the degree of pollution in the southeastern coastal areas is relatively high, and the concentration of PCBs in soil reaches 80 ng/g [26]. The content of PCBs detected in some surface soils in China is about 0.05-8.69 ng/kg, and the pollution level is relatively high [28].…”

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.
