Abstract: The aim of the study was to trace the dynamics of transformation of lead and cadmium in food chain "feed – way of processing – lamb’s products" in an area with increased environmental risk. The authors found that the processing of lamb carcasses in private yards (in the open) increase the contamination of the elements in edible parts of the carcass. The content of lead in the organs/tissues of lambs slaughtered outdoors is higher – from 40% in liver to 125% in kidneys. The exceedances of cadmium in the same tissues are from 10% to 43%.
