Abstract

For the past eight years, the Virginia Institute of Marine Science has been a participant of the National Pesticide Monitoring Program. Within the framework of this program, oyster samples have been collected from areas throughout the Chesapeake Bay.and analyzed for chlorinated hydrocarbon pesticides. The data from the last three years show that polychlorinated biphenyls (PCB's) are being concentrated by the eastern oyster, Crassostrea virginica. The highest concentrations found were always from one station, Hospital Point, in the Elizabeth River. Samples from this station, collected during the spring of 1971, contained residues of the PCB, Aroclor(R) 1254 of 2.8 ppm. For this reason, a special study was undertaken to pinpoint the source of this pollution.
