Abstract

The analysis of ecological and geochemical state of surface water in tundra and forest tundra in Western Siberia and their stability to the anthropogenic effect associated with the pollutants in sewage disposal is carried out. The river, lake and swamp waters are selected as the objects of the study: 1) the interfluve of the Taz and Yenisei rivers; 2) the eastern parts of the Gulf of Ob and Hadutte River catchment areas, which flow into the Taz Bay; 3) the left bank of the Ob River wellhead area and the interfluve of the left bank tributaries of the Ob River and the rivers flowing into the Baydaratskaya Bay. The materials of hydrochemical investigations carried out in the Tomsk Polytechnic University in 2008– 2015, with the participation of the authors of the paper, and the published data of other researchers are considered as the initial information. The chemical composition of the river, lake and marsh waters of the region is formed mainly during the natural processes and is characterized by the high values of COD (chemical oxygen demand) (14…27 mg O/dm3), concentrations of phenols (0.004…0.010 mg/dm3), NH⁺ ₄  (0.2…0.6 mg N/dm3), Fe (0.25…1.0 mg/dm3), Mn (0.052…0.140 mg/dm3) and a number of other substances. The allowable concentrations of pollutants in wastewaters formed in the hydrocarbon production are calculated. The anthropogenic impact on the ecological and geochemical state of surface water bodies is mainly limited by local areas and is demonstrated in a certain increase of mineral content, concentrations of oil products, Na+, Cl-. A statistically significant increase in the local content of dissolved inorganic substances is possible not only with the increasing of the anthropogenic load, but also with the essential modifications in the hydrological and climatic conditions.
