Concentration of heavy metals in the food web of Lake Egirdir, Turkey.
The concentration of heavy metals (Cr, Cd, Hg and Pb,) was determined by atomic absorption spectrophotometry in sediment, water, plankton and fish samples from Lake Egirdir in South-Western Turkey. Lake Egirdir is an important bird nesting and visiting areas, and it is also used as irrigation and drinking water source. The heavy metal concentrations were in the order Cd > Pb > Cr > Hg in water, Cr > Pb > Cd > Hg in sediment, Pb > Cd > Cr > Hg in plankton, Cd > Cr > Pb > Hg in the muscle and Cd > Pb > Cr > Hg in the gills of Ctenophatyngodon idella. The significant differences of concentrations occurred in water, sediment, plankton and fish tissues (Chi square test, p < 0.05). The concentrations of the heavy metals in water and fish tissues of three years old, were above the maximum permissible level for human consumption.
