The authors presented the results of a study on the content of polychlorinated biphenyls (PCBs), hexachlorohexane (ă-HCH) and dichlorodiphenyltrichloroethanes (DDTs) in perirenal fat from red deer obtained from the region of Warmia and Mazury in the years 2000-2001. Separation of the analysed com-pounds was conducted by gas chromatography. The analyses showed the presence of DDT and DDE in all samples, whereas DDD was found only in 13 samples (24% of all the analyzed samples), predominantly in trace amounts. Concentrations of DDTs and their metabolites averaged: 16.5 ěg/kg of DDTs, 8.2 ěg/kg of DDT and trace amounts of DDD. The lowest concentrations of these compounds were found in hinds and the highest in calves. Of all the analyzed substances, ă-HCH residues appeared in the smallest amounts – average 0,6 ěg/kg and whereas PCBs concentrations were the highest – average 23,7 ěg/kg. The results show that the region of Warmia and Mazury is an area characterised by low levels of pollution caused by the analyzed xenobiotics.
