This work is concerned with the comparison of the different methods of metal risk assessment in sediments based on examination of the quality of water courses in Vojvodina (Serbia). Besides, it deals with the possibility of applying remediation treatment of contaminated sediment and with the efficiency of the different methods, that is the techniques, for immobilization of sediment heavy metals by applying S/S and thermal treatments. A dominant mechanism is proposed for the process of leaching of the metals from treated mixtures. Comparison of the results obtained by different methods of sediment quality assessment showed that in some cases one approach to solving this problem is not sufficient. Metal concentrations in particular sediment samples (the Begej, the DTD Canal, the Nadela, the Sava river near Sabac) indicate the presence of contamination, the analyzed samples being of Class 4. The investigation presented in this work provided an answer to the question whether the remediation can successfully remove the contamination in the sense of the immobilization of metals in a state that will not be harmful to the environment.
