AB - The Danube, the Sava and the Tisa rivers belong to the Black Sea river basin  and they flow through many European countries, while in Serbia they flow  through the Pannonian flatland. The water quality of these rivers, which is  affected by complex anthropogenic activities and natural factors, is one of  important factors that are taken into account in the evaluation of  development sustainability of this region. Using the correlation analysis in  this paper we tested the impact of air temperature as a natural factor on  certain parameters indicating the water quality. A significant correlation  was found between air temperature and total nitrogen oxides in the Danube of  up to -0.744, namely of -0.740 on the Tisa and -0.299 on the Sava. A  significant correlation was found in electrical conductivity - up to -0.793  on the Danube, -0.226 on the Tisa, and 0.380 on the Sava. Correlation links  were found between air temperature and O2, BOD, as well as suspended matters  saturation percentage, but their correlation values are significantly lower.  Based on the results of the research it was concluded that air temperature  had low effect on changes in water quality during the year and that  anthropogenic impact was far more dominant.
