Abstract
The wastewater canal Vojlovica of the Pančevo industrial area Serbia is the main collector of the effluents from the local industrial complex The canal is directly connected to the Europe’s second largest river the Danube Here we present a chemical and microbiological analysis of the sediment in order to determine the fate of pollutants over the years as well as its current condition Dry matter clay and organic matter content a Kjeldahl ammonia phosphorus metals and polychlorinated biphenyls as well as polycyclic aromatic hydrocarbons concentrations were measured Microbiological analysis included heterotrophic and oildegrading bacterial counts isolation of the phenanthrenedegrading bacteria and identification of cyanobacteria Generally in comparison to the results from previous studies concentrations of the measured pollutants have been in a decline Specifically the metal and polycyclic aromatic hydrocarbon concentrations were reduced whereas microbial counts and toxicity tests did not indicate significant pollution The obtained results are probably a consequence of an improved wastewater treatment and microbial degradation of pollutants
