Wastewaters from pig breeding farm near Vrbas settlement (Serbia) are distinguished into lagoon and thereafter are released into melioration drainage channel network. Detected concentrations of analyzed nutrients and trace elements in channel sediment samples taken at upstream locations (before discharge point from lagoon) and downstream (after discharge point from lagoon) are significantly different. At downstream (vs. upstream) locations nutrients content was increased by 2-fold (for N, S and K2O), namely by 4.5-fold (for P2O5), whereas trace elements content was increased by 10-30%. The most significant increment of trace elements was observed for zinc (greater than 9-fold) and for copper (4.6-fold). At the same time, present copper concentration of 185 mg/kg, and zinc concentration of 651 mg/kg are above maximum permited values in sediments (1.8-fold, namely by almost 2.2-fold respectively) what could implicate detrimental effects to overall environmental resources.
