Sažetak
Heavy metal accumulation was studied in a free- living population of the European badger, Meles meles L. (Carnivora, Mustelidae) from the Croatian Danube Region. Total of 29 badgers has been collected in the period 2009-2011 by regular hunt or found killed in road traffic accidents at 20 localities in the surveyed area.Concentrations of cadmium and lead were analysed by atomic absorption spectrophotometry in the muscle, kidney and liver. Mean Cd concentration was higher in the kidney (3.046 mg kg-1) compared to muscle (0.074 mg kg-1) and liver (0.395 mg kg-1), thus confirming kidney as a target organ for the heavy metal accumulation in the badger. Mean Pb concentrations was higher in the liver (0.197 mg kg-1), followed by kidney (0.190 mg kg-1) and muscle (0.131 mg kg-1). Mean Cd concentrations in the muscle and kidney and Pb in the muscle, exceeded the maximum allowable values prescribed by the EU and Croatian food safety standards. Assumed sources of heavy metals are geological ground, sediments and water in the floodplain, emissions from the road traffic, improper waste disposal and use of agricultural chemicals. Further research is needed to identify the source of contamination in order to preserve the health of animals and humans.
