|
Tabulated data are given on the concentrations of selected pollutants (polychlorinated biphenyls, mercury, and cadmium) in tissues of snapping turtles (Chelydra serpentina) collected from various sites in Minnesota in 1981. Conclusions 1. Low levels of PCBs, less than .086 mg/kg, were found in the meat of all turtles collected from the Mississippi River and other Minnesota locations. 2. High levels of PCBs, up to 60.5 mg/kg, were found in the fat of turtles collected from the Mississippi River below the Twin Cities. 3. PCB concentrations at or below 5 mg/kg were found in the fat of turtles collected at other locations. 4. Low levels of mercury, less than 0.03 mg/kg, and cadmium, less than 0.025 mg/kg, were found in all of the turtles sampled.
