The possibility of removal of PCBs (Polychlorinated Biphenyls) in soil was studied using biological method. The effects of soil and co-substrate on both PCBs reduction rate and chloride ion concentration in soil were investigated. It was shown that PCBs concentration of all the soils used in this study were reduced from 5ppm to below 1ppm after 60days, also chloride ion concentration in slurry increased, Results showed that leaf mold and humic acid as co-substrate do not seem to be effective for biological treatment of PCBs in soil,
