Abstract
An increase of technogenic load on the catchment area with a decrease of the volume of water protection measures leads to spread of surface water pollution. The paper considers the chemical composition of surface waters in Khanty-Mansi autonomous okrug – Ugra. The technique for analyzing the chemical composition of surface waters based on the combined application of the method of cluster analysis is presented. In this work, the concentration of metal ions in the rivers under study was determined. It was found that concentrations of iron and zinc ions exceeded the maximum permitted concentrations for fishery rivers (MPC) in 100% of samples, as for copper concentration an excess of MPC was noted in some cases. The spatial dynamics of the distribution of chlorides and oil hydrocarbons in surface waters is considered. According to the monitoring data, the analyzed surface water samples had very low concentrations of chlorides and oil hydrocarbons.
