Cadmium, lead, copper and zinc were quantified using a validated ICP/MS method in the tissues and organs of 82 specimens of red deer of different sexes and ages, which had been hunted at the Great Lakes Land region in the north-eastern of Poland in 2000-01. Copper and zinc occurred in liver, kidney and muscle tissue of red deer at concentrations of 6.4-29, 3.3-7.2 and 1.9-6.4, and of 19-43, 17-41 and 19-64 mg kg(-1), respectively, which are considered typical for the species, age and gender compared with values noted for some other wild and domestic ruminant species elsewhere. For cadmium and lead, the concentrations decreased in the order kidney > liver > muscle tissue, with overall means of 2.2, 0.19, and 0.10, 0.31, and 0.26, 0.22 mg kg(-1) wet weight, respectively. The cadmium content of the kidney of a proportion of red deer sampled exceeded the legal tolerance limits set in Poland. The means (but not individual animal data) obtained for cadmium in kidney and liver correlated (0.99) with the age of red deer. Also, the lead content of the muscle meat of red deer for many carcasses exceeded the legal limit, which was probably due to contamination from the fine dust particle remains from the lead bullets used.
