Trace metals (Cd, Pb, Cu, Zn and Cr) distribution in sediment along east coast of the Adriatic Sea (Croatia)

Surface sediment samples collected from five stations along the east coast of the Adriatic Sea were analysed for Cd, Pb, Cu, Zn, Cr, organic matter and carbonate, and granulometric composition. Trace metal concentrations in the sediments depend on pollution sources, on local environmental characteristics, as well as on geology of the surrounding terrestrial environment. Factor loadings of PCA indicated that chromium is mostly natural, lead and zinc probably is anthropogenic, while cadmium and copper are of both natural and anthropogenic origin. The obtained trace metal concentrations indicate that the investigated areas are not considerably polluted.
