Pollution of the environment with heavy metals is a serious problem, which is recognized in most countries of the world. Metals accumulate in the liver, and particularly in the kidneys. The present study provides information about the concentrations of metals in animal organs from both rural and industrial areas. It was surprising that the Pb, Cd, Zn, Cu, Mn and Fe contents in muscle, liver, kidney, heart and spleen in industrial areas were higher than in the same organs of rural areas. Lead concentrations in bovine liver and kidney, in buffalo, elk, sheep and goat kidneys as well as Cd in elk liver and kidneys were higher in the present study than the recommended values. The effect of washing for bovine muscle, liver and kidney using tap water and other detergent solutions on the metals was studied. Washing by only tap water was less effective than the other detergent. The results indicate the efficient role of washing by acidic detergent in the reduction of Pb, Cd and Zn from naturally contaminated meat compared with neutral and alkaline detergent.
