    Abstract:
    Four species of shellfish (Mytilus galloprovincialis, Ostrea edulis, Chlamis varia and Venus verrucosa) were collected during the autumn 2011 and spring 2012 along the eastern Adriatic coast from six shellfish harvesting areas (all species) and 13 breeding sampling areas (mussels) to assess As, Cd, Hg and Pb levels and the human risks of shellfish consumption. The mean metal concentrations (wet weight) in the examined species ranged from 1.420 to 9.575mg/kg for As, 0.034 to 1.270 for Cd, 0.005 to 0.680 for Hg and 0.140 to 2.072 for Pb. Examination of the spatial distribution of As, Cd, Hg and Pb revealed statistically significant differences among the studied areas. Since the concentrations were below the maximum prescribed by the laws of the EU and Croatia (the concentrations slightly exceeded the upper limits for three samples; Pb, Cd and Hg) and the hazard index, (HI) for Cd, Hg and Pb were below 1 and the target cancer risk (TR) for As was lower than 1×10(-6), there is no human health risk of consumption of shellfish from Croatian waters.
