Abstract
Concentrations of heavy metals (Cu, Zn, Pb, Cd) and long-lived radionuclides
(U, Th, Cs) along the Iron Gate reservoir of the River Danube in Serbia were
determined. In years 2005-2009, water and sediments were sampled at six
sites along 200 km of the River Danube from Belgrade to Djerdap (Iron Gate)
hydroelectric power plant. The concentrations of heavy metals in sediment
were found to be in the intervals: 27.9-149.3 mg kg-1 for Cu, 55.2-228.4 mg
kg-1 for Zn, 13.5-71.6 mg kg-1 for Pb , 0.3-25.2 mg kg-1 for Cd, and
4.0-17.5 Bq l-1 for 137Cs. These values are in correlation with
concentrations in river water when expressed by the equilibrium coefficients
(Kd) between solid and liquid phases. The behaviors of heavy metals were
evaluated by applying models for the prediction of pollutants? behavior in
rivers. The fluxes of heavy metals from water to sediment and vice versa
were also determined.
