Concentration of selected essential and possibly toxic metals in roe deer (Capreolus capreolus L) tissues in western Croatia

Given the ever-growing need for monitoring the levels of heavy metals in both environment and the wildlife we have selected organs (brain, liver and kidney) and muscles of roe deer as a parameter reflecting these levels. The premise of this work was to establish the baseline for different essential (Na, K, Ca, Mg, Fe) and trace (Cu, Mn, Zn and Al) metals in adult roe deer (herbivorous browser) collected in western Croatia in 2014. The concentration of these elements was determined using validated digestion and ICP-OES methods and is expressed as mgkg-1 dry weight. The highest mean copper, manganese and iron concentrations were determined in liver and kidney tissues, aluminium accumulated in muscle tissue and zinc in kidney>muscle>liver tissues. Standard high concentrations of essential elements (Na, K, Ca and Mg) were observed in all tested tissues. Concentrations of investigated metals are dependent on the vegetation period, and different physiological activities of the animal, like pregnancy in females, antler growth in males, etc. Future studies will take this conditions in consideration.
