DISTRIBUTION OF CU, FE, ZN, AS, CD AND PB IN SHEEP ORGANISMS AFTER EXPERIMENTAL INTOXICATION WITH COPPER-OXIDE FROM INDUSTRIAL FLUE DUST

In eight sheep (improved valaska) cumulations of Cu, Fe, Zn, As, Cd an d Pb were investigated after experimental intoxication with copper oxi de from flue dust of a copper producing plant. The highest concentrati ons of Cu (2138.40 +/- 1090.96 mg/kg of dry matter) were detected in l iver. Kidneys, wall of small intestine and spleen proved also to posse ss high cumulative amounts of copper. Fe was mainly deposited in splee ns and kidneys, Zn in kidneys and liver, the highest concentrations of As were found in the dry matter of kidneys (13.09 +/- 3.82 mg/kg); th e ones of Cd in bones (0.36 +/- 0.10 mg/kg) and those of Pb in kidneys (5.53 +/- 2.19 mg/kg).
