Concentrations of cadmium (Cd) were determined in the samples of 144 animals around 1 and of 144 animals around 4 years old. Cd was analysed by inductively coupled plasma-optical emission spectrometry (ICP-OES), after microwave digestion. Cd concentrations were higher (p < 0.05) in kidney than in liver and higher (p < 0.05) in older animals than in young ones. In domestic Balkan goat which was raised in a free-ranged system Cd accumulation was lower (p < 0.05) than in Alpine goat raised in an intensive production system. Geographic region did influence Cd accumulation only in older animals. Higher Cd levels (p < 0.05) were determined in goats from Serbia. The highest obtained Cd concentrations in both tissues were lower than maximum levels set by European and national legislation for ruminants (cattle and sheep).
