| Abstract: | This paper reviewed mechanisms in phytoremediation of polychlorinated biphenyls (PCBs) including phytoextraction, phytotransformation and rhizoremediation. Non-genetically modified plants and rhizobacteria have some hereditary defects in PCBs-contaminated soil remediation. Genes of PCBs metabolism introduction can overcome these hereditary defects. Meanwhile, some recent developments in phytoremediation for polychlorinated biphenyls contaminated soils were introduced and some research trends in this field were discussed. |
