Element contents in muscle tissue of Prussian carp from different lakes in an urban area
The aim of this study was to determine the content of some elements (Pb, Cd, Hg, Fe, Cu, Zn, As) in muscle tissue of Prussian carp (Carassius auratus gibelio) from seven different lakes in the Belgrade region, Serbia. Concentrations of Pb, Hg and As in fish muscle tissues from all examined lakes were under the maximum residual levels prescribed by the European Union (EU) and the maximum allowed concentrations (MAC) for Serbia. In all investigated fish, levels of Cd exceeded maximum allowed concentrations (0.05 mg kg-1). Data on the finding of elements in fish speak concurrently about the safety of fish as food and are good indicators of environmental pollution.
