Levels of PCBs and trace metals in Crab Orchard Lake sediment, benthos, zooplankton, and fish
Concentrations of trace metals and PCBs in six species of fish, zooplankton, macrobenthos, sediment, and water were studied in Crab Orchard Lake, Williamson County, Illinois. Eleven sites were chosen throughout the lake, including one site (site 10) near an abandoned dumpsite of a former electrical transformer manufacturing facility. PCB levels in the selected components from site 10 were considerably higher than the other sites. Thirty-eight percent (17/45) of fish fillets from various species at this site exceeded the 2.00 mg/kg FDA guideline for PCBs. PCB concentrations in fish were variable, and little relationship existed between age or size and PCB concentrations in most species. Common carp and channel catfish had higher PCB levels than the other species examined. Trace metals were low in fish and other components analyzed and were comparable to literature values for the midwestern United States. Mercury was the only trace metal to exhibit a significant positive relationship with age or size of fish. Mercury was also the only trace metal to exhibit biomagnification.
