Evaluation of the contamination degree of roe-deer with cadmium and polychlorinated biphenyls in Warmia and Mazury district.

The results of investigations concerning degree the contamination degree with cadmium and polychlorinated biphenyls (PCB's) of roe-deer organs hunt in seven selected areas of Warmia and Mazury voivodship are presented. The highest mean cadmium content in the organs investigated was found in the samples from Głebock area (liver - 0.0576 mg/kg, kidney - 3.351 mg/kg) and the lowest one was observed in the samples from Pisz area (liver - 0.181 mg/kg, kidneys - 1.653 mg/kg). Mean level of polychlorinated biphenyls residues in the roe-deer fat from Warmia and Mazury district was 0.004 mg/kg. The highest PCB's mean concentration was found in the roe-deer fat samples from Milomlyn area (0.008 mg/kg), and the lowest one in those from Głebock area (0.002 mg/kg). Presented levels of investigated xenobiotics do not make at present (except cadmium in kidney) any toxicological threats for venison consumers in Warmia and Mazury district.
