abstract: The aim of the study was to assess the degree of accumulation of Cd, Cu, Hg, Pb, Zn in muscles and livers of hens from extensive keeping systems in copper industry region. Samples of muscles and livers from 25 hens from the copper mining Glogow area were used as material. The mineralisation of samples was performed in a high-pressure rotation microwave oven CEM (USA) in spectrally pure nitric acid. The level of elements was measured using the ISP-MS method (Varian Ultramass 700). Hg concentration was measured using spectroscopy method automatic analyzer AMA -254. The organ accumulating higher amounts of heavy metals was liver. In muscles, Pb concentration exceeded the permissible concentration. In liver, the level of Pb and Cd exceeded the permissible concentration. A positive relation between concentration of Pb in muscles and liver and negative for Zn was observed. The study does not show any relation between the content of heavy metals in muscles. A positive relation between concentration of Cd and Pb in liver was observed. Negative relations between concentration of Cd-Pb and Zn-Cu were observed.
