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 Đerdap (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

Seasonal spatial and temporal changes of selected eco-chemical parameters in section of the Danube River flowing through Serbia were analyzed. Data for electrical conductivity (EC), dry and suspended matter, residue on ignition, chemical oxygen demand (COD), biochemical oxygen demand (BOD-5), ultraviolet extinction, dissolved oxygen (DO), oxygen saturation, pH, nitrates, total phosphorus, and nitrogen were collected between 1992 and 2006. The use of monthly medians combined with linear regression and two-sided t test has been proven to be the best approach for resolving trends from natural variability of investigated parameters and for determining trend significance. Patterns of temporal changes between different months were examined. It was also determined that spatial trends of some parameters oscillate in predictable manner, increasing in one part of the year and declining in the other. Regression slope coefficients, an excellent indicator for determining when the water quality is changing the most along the course of the Danube, reach their maximum during summer for temperature (t), electric conductivity, nitrates, and total N, while in the same season suspended matter, COD, BOD-5, DO, and oxygen saturation coefficients reach their minimum. Correlations for used data sets of selected parameters were analyzed for better understanding of their behavior and mutual relations. It was observed that as Danube flows through Serbia, its general eco-chemical status either stagnates or improves, but the rate of river self-purification often depends on the season of the year.
