Popis:	The impact of salinity and water exchange rate on the accumulation of heavy metals in the benthic fish Zosterissesor ophiocephalus, collected from the shallow sublagoons Tholi and Paleopotamos, was studied. Both sublagoons are influenced by the intensive agricultural activity of the surrounding area in terms of the chemical substances’ drainage, and by the untreated sewage discharges of an urbanized area with Paleopotamos being affected in lesser extent. Paleopotamos is characterised by restricted water renovation, resulting to much higher salinity than Tholi. The bioaccumulation of the heavy metals studied (Manganese, Zinc and Copper), reveals differences among the metals with females showing higher values. Specimens from Paleopotamos showed statistically significant higher bioaccumulation of the heavy metals in both sexes, which is attributed to the extremely high salinity of this sublagoon.
