    摘要: A method is provided for bioremediating aged PCBs such as Aroclor 1260 in aquatic sediments under anerobic conditions by stimulating the dechlorination of the aged PCBs through addition of brominated or iodinated biphenyls or through the addition of a microbial inoculum from another location in addition to brominated or iodinated biphenyls.

    摘要: A method for stimulating microbial dechlorination of the unflanked para-chlorine substituent of PCBs having one or two unflanked para-chlorine substituents in an active PCB-contaminated sediment having a population of microorganisms capable of para-dechlorinating PCBs involves incubation of the sediment with a fluorochlorobiphenyl compound such as 2,6-difluoro-4-chlorobiphenyl that has a para-chlorine at position 4, hydrogens on positions 3 and 5, and fluorines on positions 2 and 6, for a time and under conditions sufficient to decrease the levels of PCBs containing unflanked para-chlorines.
