Sažetak
Concentrations of Cd, As, Hg and Pb were measured in muscle, liver and kidney of three cetacean species Stenella coeruleoalba, Grampus griseus and Tursiops truncatus from the Croatian waters of the Adriatic Sea. In all three dolphin species Cd levels decreased in tissues in the order: kidney > liver > muscle, while As and Pb levels decreased in the order: liver > kidney > muscle. However, Hg levels decreased in different order for three species. In all tissues of three dolphin species concentrations (μg/g) ranges were: Hg 0.96 to 1790, Cd 0.007 to 17.6, As 0.02 to 8.95, Pb 0.01 to 1.59. The highest levels measured in Risso’s dolphins (μg/g) were determined in tissues: Hg 1115, As 2.41 and Pb 0.63 in liver, Cd 14.9 in kidney. Statistically significant differences between the three dolphin species were determined for Cd, Hg and Pb in liver tissues, for As in muscle and for Cd in kidney. Significant correlations of metals between tissues were determined in all three species. The results presented give an indication of the environmental condition with regard to the content of toxic metals along the eastern coast of the Adriatic Sea.
