Metal accumulation in sediment, water, and freshwater fish in a Dam Lake

Metal concentrations were determined in water, sediment, and freshwater fish samples (Squalus cephalus, Barbus esocinus, and Barbus xanthopterus) collected from Karakaya Dam Lake, Turkey, to estimate the risk of human consumption and pollution. Metal concentrations differed between the species (p   Zn = Cu in water and Fe > Zn > Mn > Ni > Cu in sediment. In general, the accumulation order of elements in the tissues all of the species sampled were found as Fe > Zn > Se > Mn > Cu > Ni > Cd in muscle, Zn > Fe > Mn > Se > Cu > Ni > Cd in gills, Fe > Zn > Se > Mn > Cu > Ni > Cd in liver and gonad, and Zn > Fe > Cu > Mn > Se > Ni > Cd in kidney. It was concluded that the fish from the dam...
