Distribution of Hg, Cu, Zn, Cd and Pb in surface sediments from the coastal region of the central Adriatic

Surveys of Hg, Cu, Zn and Cd concentrations in surface sediment began in 1983 at six main stations along the central Adriatic coast. The results of chemical and statistical analysis for 1983-1995 show that the highest concentrations of almost all the heavy metals examined are found in the naturally enclosed areas with maarginal biodegradation abilites (Kaštela, Šibenik, Gruž Bays), where some heavy metals have already accumulated in edible organisms (mussels, fish) in concentrations higher than the WHO recommended values for human consumption. Although these bays are still receiving uncontrolled quantities of different pollutants, it is encouraging that owing to the semi-enclosed nature of the bays, pollution by the these metals has not yet reached the open sea.
