In this work, the horizontal and vertical distribution of metals in the sediment of the DTD canal was studied, in a 6 km long polluted section between Vrbas and Bezdan. The assess sediment quality and the bioavailability of heavy metals, sediment samples were analyzed for total metal content, acid volutile sulphides (AVS) and simultaneously extracted metals (SEM). A high total metals content was determined (mainly Cu, Ni and Zn), which indicates that the sediment requires remediation. The AVS and SEM results show that in almost every profile, the molar concentration of metals is less than the molar concentration of sulphides, which suggests that in practice, the metals are not bioavailable. The high metals content of the sediment means that drudging of the canal will be necessary, during which, attention will have to be paid to avoid causing negative effects from the metals present in the sediment.
