Comparing polychlorinated biphenyl concentrations and patterns in the Saginaw River using sediment, caged fish, and semipermeable membrane devices

Article Abstract:

Amounts of polychlorinated biphenyls in fish and semipermeable membrane devices are measured against those in sediment to determine the level of the compound in Michigan's Saginaw River.

PCB concentration in fish in a river system after remediation of contaminated sediment

Article Abstract:

The level of PCB (polychlorinated biphenyls) concentration in major river systems in southern Sweden significantly decreased over time as a result of bioremediation initiatives. By comparing statistics gathered in 1996 to those derived in 1991, it was found that PCB concentration in pike decreased by an average of 6% per year, with a corresponding drop in the volume of fishes in the sample sites. Results gathered from the study imply that changes in background exposure must be noted when evaluating the efficiency of bioremediation efforts.
