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.
