According to the analysis of nutrient concentrations in the water stream of Krivaja at the profiles Mali I?oš and Srbobran in the period 2001-2009. it was found that the water quality, taking into account average content of ammonium ions at Mali I?oš profile is outside of class, at profile in Srbobran III / IV class, while the concentrations at the profile of Mali I?oš were consistently higher (up to 79%). According to the average values of nitrite, both water profiles are assigned to III / IV class. The content of nitrite was higher in the profile of Mali I?oš (up to 77%) except 2007th, when it was for 31% higher at profile Srbobran. According to the average nitrate content of water, both profile belongs to I / II class and the nitrate content appeared to be higher at profile Srbobran (up to 131%). In all nitrogen parameters, there were significant differences in the concentrations of the two profiles at significance level ? = 0.01. The concentrations of orthophosphate and total phosphorus were higher at profile Srbobran (up to 118%, or up to 91%) than in 2002. year, when 21% were higher at profile Mali I?oš. For phosphoric parameters there were no significant differences in the concentrations of the two profiles at significance level ? = 0.01, but the concentration constantly ranged above the recommended values, thereby creating conditions for the occurrence of eutrophication.
