The concentrations of As, Cd, Cu, Hg, Pb and Zn were measured in four shellfish species (oysters, mussels, scallops, warty venus) collected along the Istria Peninsula coast during autumn 2013. Mean metal levels in shellfish ranged as follows (mg/kg): As 1.69-3.91, Cd 0.15-0.99, Hg 0.06-0.2, Pb 0.33-0.74, Cu 1.23-36.2, Zn 16.3-511. Statistical analysis showed a significant difference in As (p < 0.05), Cd, Pb, Hg, Cu and Zn (p < 0.01, all) levels among shellfish species. The highest metal concentrations were found in oysters (mg/kg): As 3.91, Cd 0.99, Cu 36.2 and Zn 511. The highest means of Pb and Hg were measured in (mg/kg): warty venus 0.74; scallops 0.12. The estimated daily intakes for oysters shown it as a good source of Cu and Zn. The higher contribution of Cd and As levels to the provisional tolerable weekly intake in shellfishes suggest a careful approach for consumption. © 2015 Springer Science+Business Media New York.
