Reductive Dechlorination of Polychlorinated Biphenyls (PCBS) in Marine Harbor Sediments

Abstract

For the first time reductive dechlorination of PCBs was shown to occur in marine and estuarine microcosms from sites with ambient temperatures below 10 degrees centigrade. It was shown that the types of activities are influenced by the location of the site and the ambient temperature. In addition, it is now clear that non-indigenous dechlorinating organisms can be added to sediments microcosms to dechlorinate PCBs. These studies suggest that reductive dechlorination of PCBs has the potential to occur in coastal regions with lower ambient temperatures. The result also suggest that active biotreatment of PCB impacted dredge spoils by augmentation may be possible in colder climates.
