For analysis, each tissue sample was dissolved in a solution of nitric acid p.a. （HNO3：HzO = 2：1）; sediment sample in solution of acids （HF-HNO3-HCIO4） and analyzed for presence of Cd, Pb by the atomic absorption spectrophotometer （AAS） Varian Duo 240FS and 240Z. Our results confirmed hygienic harmless of bottom sediments in water reservoir Kolifiany. The Cd, Pb contents in sediments represent no risk within their input into the fish organisms. The Cd content in fish meat is lower than maximum available amount given by legislative norms, and the contents of Pb in fish meat too. The results of Cd, Pb content determination in carp body confirmed that fish muscles belong to suitable foodstuff for the human consumption.展开更多

[ Method] I.aad acetate （100 mg/L） and/or cadmium chloride （50 mg/L） were administered in drinking water to 120 individuals of 40 -week -old hyline layers for 8 weeks. [ Result] Compared with the Cd group, the Cd content in various tissues, except kidney and femur, in Cd ＋ Pb group all increased, but the difference was not significant （P 〉 0.05 ）. The Cd contents in kidney and femur in Cd group were significantly higher than that in Cd ＋ Pb group. Compared with the group Pb, the Pb contents in breast muscle and kidney in Cd ＋ Pb group decreased significantly （ P 〈 0.05 ） ; the Pb contents in femur decreased extremely （ P 〈 0.01 ） ; while the Pb contents in leg muscle, heart and spleen increased significantly （ P 〈 0.05 ） ; the Pb contents in liver and glandular stomach were almost the same. Compared with the control group, the Cd content in various tissues in Pb group increased significantly （ P 〈 0.05 ） ; no significant changes were observed for Pb content in Cd group. [ Conclusion] Deposit of Pb and Cd in poultry body had complex interaction.展开更多
