Opis (eng)

This work represents an advantage of using macrophytes as indicators for ecological state class prediction based on orthophosphate anions concentrations instead of calculating water quality index, Serbian Water Quality Index (SWQI) concretely. Calculating of SWQI requires standard laboratory methods of water sampling that include sampling chemical parameters such as pH, temperature, orthophosphate anions, ammonium ions, total organic nitrogen concentrations, temperature, conductivity, values of biological oxygen demand, oxygen saturation in percents and amount of suspended solids. Macrophytes, as an official biological parameters for prediction of ecological state of rivers, are recognized as good predictors of ecological state classes based on concentrations of orthophosphate anions. Phragmites australis L. is an indicator species for river sections that belong to IV class of ecological state based on orthophosphate anions concentrations. For all river sections where presence of this macrophyte was detected during Joint Danube Survey 3 (JDS 3) scientific research expedition was calculated Serbian Water Quality Index (SWQI). Values of SWQI predicted good ecological state even for sampling points where among concentrations of orthophosphate anions river section belong to IV class of ecological state. This fact lead us to conclude that in situ prediction of ecological state of river according to orthophosphate anions concentrations is more specifically by presence of macrophyte Phragmites australis L. then by calculating quality index that requires expensive chemical analysis.
