Conclusions

  1. 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. 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. 3.

    PCB concentrations at or below 5 mg/kg were found in the fat of turtles collected at other locations.

  4. 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.
