Abstract
Samples of skeletal muscles, liver and kidneys of young wild boars from Moslavina and Slavonia were analysed for cadmium content. Organ samples were taken from wild boars (up to 1 year old) in the 2007/2008 hunting season from the hunting grounds: Črnovščak (n = 8) and Spačva (n = 9). The highest value of cadmium measured in muscles was 0.0029 μg/g (Spačva), in the liver 0.0874 μg/g (Črnovščak) and kidneys 0.8509 μg/g (Črnovščak), which is the highest concentration of Cd from all studied tissues. All measured concentrations were lower than the reference values according to Croatian regulations for Cd in food. Cd concentrations in muscle tissue were much lower than the concentrations in the liver and kidney. Cadmium median values in the muscle tissue of wild boars from Moslavina (0.00065 μg/g) were lower than the values in wild boars from Slavonia (0.0008 μg/g), but not significantly, while the median concentrations of Cd in liver and kidney tissue were higher in wild boars from Moslavina (0.0483 μg/g and 0.5259 μg/g), in comparison with those in Spačva (0.0283 and 0.4770 μg/g). Additionally, statistically significant differences were only defined for liver tissue. The results of this research indicate that: 1. even young wild boars (aged up to 1 year old) can be bioindicators of environmental pollution with Cd; 2. The researched area Črnovščak is under stronger anthropogenic influence than the Spačva hunting ground; 3. the amount of Cd in the tissues is lower than the permitted concentration.
