Kuksanov V.F., Debelov P.V., Ishanova O.S., Kozlova Y.A., Romanov A.S. EKOLOGICHESKAYA CHARACTERISTICS OF WATER QUALITY IN MAJOR LAKES OF THE FAR EAST DISTRICT OF THE ORENBURG REGIONAccumulation of chemical elements and their receipt in objects of environment are result of industrial and agricultural activity of the person. At the same time, the significant role in pollution of environments is rendered by natural factors, especially in places of concentration of deposits of mineral resources, in particular copper колчедановых, nickel ores. Studying of the quantitative content of harmful chemical impurity in water objects, in particular in the territory of the Svetlinsky region of the Orenburg region having deficiency in fresh water wasn't carried out in connection with a lack of ecological information on an assessment of a surface water of the main lakes of the area, otsutstvy long-term plans of their use in the production, economic and household and recreational purposes earlier. For the solution of this problem authors conducted hydrochemical research of waters of the main lakes of the Svetlinsky region of the Orenburg region in 2010 and 2015, the analysis of the received results is made and the ecological assessment of these water resources is for the first time given. In article the arisen reasons (natural and anthropogenous factors) having negative impact on qualitative composition of lake water are also considered. Water resources of the Svetlinsky region of the Orenburg region include, first of all a network of drainless lakes of the large, average and small size. Are most significant lakes: Shalkar-Ega-Kara, Zhetykol, Obalykol, Kayrankol. These and other lakes are of special value for the nesting and flying natatorial — swans, geese, ducks and other representatives of aviafauna. Hydrochemical indicators of quality of lake waters according to the content of sulfates, chlorides, ammoniyny nitrogen, oil products and other substances exceed the maximum-permissible concentration (MPC). The majority of lakes in adverse weather conditions (2013—2014) completely or partially dried up that testifies to need of carrying out on them environmental monitoring. Key words: lakes of the Svetlinsky area, quality of waters, laboratory researches of tests of water, sources of negative impact on natural waters, indicators of chemical pollution, standards, the analysis of the received results.
