Abstract

The aim of the study was to evaluate the cadmium and zinc content in the kidneys and liver of moose from north-eastern Poland. Animals were divided with respect to their age. The mean concentration of cadmium in the kidneys of moose studied was 11.31 mg kg-1, while in the liver it amounted to 2.68 mg kg-1. Age had a significant effect on the content of cadmium in both organs. In the muscles of most animals studied, the cadmium concentrations were below the detection limit. Elevated concentrations were found in three individuals only. Older animals had over six times higher concentrations of cadmium in both kidneys and liver than younger individuals. The cadmium content in kidneys increased with animals' age while no such relationship was found for zinc. Although older animals had higher mean concentrations of zinc in kidneys, liver, and muscles, the two age groups did not differ significantly. The mean concentration of zinc in the kidneys of moose studied was 38.83 mg kg-1, while in the liver it amounted to 29.03 mg kg-1. The cadmium concentration in the kidneys was significantly correlated with the cadmium concentration in the liver (r = 0.53, p ≤ 0.01) and with the zinc concentration in the kidneys (r = 0.52, p ≤ 0.01). The data obtained within study correspond with analyses results of the organs of healthy moose in Sweden.
