Reductive dechlorination of the ortho moiety of polychlorinated biphenyls (PCBs) as well as of meta and para moieties is shown to occur in anaerobic enrichments of Baltimore Harbor sediments. These estuarine sediments ortho dechlorinated 2,3,5,6-chlorinated biphenyl (CB), 2,3,5-CB, and 2,3,6-CB in freshwater or estuarine media within a relatively short period of 25 to 44 days. ortho dechlorination developed within 77 days in marine medium. High levels of ortho dechlorination (>90%) occurred when harbor sediments were supplied with only 2,3,5-CB. Incubation with 2,3,4,5,6-CB or 2,3,4,5-CB resulted in the formation of the ortho dechlorination product 3,5-CB; however, para dechlorination of these congeners always preceded ortho chlorine removal. ortho dechlorination of PCBs is an exceedingly rare event that has not been reported previously for marine or estuarine conditions. The activity was reproducible and could be sustained through sequential transfers. In contrast, freshwater sediments incubated under the same conditions exhibited only meta and para dechlorinations. The results indicate that unique anaerobic dechlorinating activity is catalyzed by microorganisms in the estuarine sediments from Baltimore Harbor.
