Metals in sediments of Rhodes Harbour, Greece

Metal concentrations (Cd, Cr, Cu, Fe, Mn, Pb and Zn) were determined in the 0.5 HCl extractable fraction of surface sediments collected in Rhodes Harbour, Rhodes Island, Greece. The metals related to human activities (Cu, Pb and Zn) were found in relatively higher concentrations in the harbour sediments and in some cases showed important enrichment compared to the nonpolluted coastal sediments. The highest metal enhancement was found in the fine sediments of the Mandraki Harbour, which is located in the vicinity of the main sewage outfall of a densely populated area.
