EKOLOGICHESKAYA CHARACTERISTICS OF WATER QUALITY IN MAJOR LAKES OF THE FAR EAST DISTRICT OF THE ORENBURG REGION ^{[№ 9 ' 2015]}
Accumulation 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.

CHEMICAL POLLUTION OF SOILS OF THE TERRITORY ADJACENT TO SOROCHINSKO-NIKOLSKOMU TO MESTOROZHDENY ^{[№ 6 ' 2015]}
On oil production volume Russia holds a leading position in the world. On objects of an oil and gas complex where are observed the constant intensification of technologies connected with increase of temperatures and pressure, strengthening of single capacities of installations and devices, existence in them of large supplies vzryvo-, pozharo- and the toksikoopasnykh of substances. At production and use of natural resources there is a deterioration of ecological properties of environment that bears threat of life of many live organisms including the person. Soils are capable to absorb and hold chemicals, protecting from them water, air and plants. Respectively control of efficiency of the soil in restriction of migration of chemicals in the technogenic loaded landscapes is the most important link of geochemical monitoring of soils. Research of the territory adjacent to the Sorochinsko-Nikolsky field showed that on an indicator of chemical pollution of soils the main part of the territory experiences considerable anthropogenous strain and is characterized as a zone with an intense ecological situation.

ECOLOGICAL STATUS OF THE RIVER URAL AND RUSSIAN-KAZAKH OPPORTUNITIES TO IMPROVE THE QUALITY OF ITS WATERS ^{[№ 6 ' 2015]}
The article gives a brief description of the ecological status of the river Ural, quantitative indicators of the quality of its waters. The analysis of statistical data of the state environmental monitoring is carried out on the biological and chemical indicators. The authors consider the main areas of implementation of environmental measures and the Russian-Kazakh cooperation in the field of nature protection of the pool of the Ural. Summary: the Ural River is one of the major rivers of Europe and the increasing impact of human needs in the Russian-Kazakhstan joint action on environmental issues. The quality of surface waters of the pool r.  Ural does not meet sanitary-hygienic and environmental requirements on all its length from source to mouth. Within the Orenburg region surface water quality r. Ural characterized as "polluted" and "very polluted". This is due to the high content in water copper, zinc, iron General and other chemical elements. The most polluted tributaries r. Ural river is the Ilek, Blava, Most Urtzika, Sakmara, Great Satyr and other. To solve the conservation pool r. Ural necessary practical steps including improvement of Russian and Kazakhstan environmental legislation, development and implementation of the interstate program of salvation r. Ural-based "Schemes of complex use and protection of water bodies in the basin r. Ural, the increasing volume and quality of environmental monitoring, development and implementation of a comprehensive program of continuous ecological education and enlightenment. As a priority action should be to make changes in the State program "environmental Protection of the Orenburg region for 2014—2020" in honor of the expansion of the network of specially protected natural (water) areas, development of methods of compensation for damage to natural complexes in cross-border transfers of pollution, increased funding of environmental measures through targeted use of pollution charges the environment and other activities, primarily legislative and normative-legal nature of managerial decision-making on education intergovernmental authority for the protection r. Ural and international information-analytical center on a continuing basis.

ESTIMATION OF INFLUENCE OF EMISSIONS OF DIVISIONS KAPITONOVSKOGO OF A DEPOSIT ON QUALITY SOIL COVER ^{[№ 12 ' 2011]}
In the given work questions of an estimation of influence of various sources of pollution of atmospheric air on Kapitonovskogo a deposit of Open Society "Ujyralneftegaz" on an ecological condition grounds are considered. Ranging territory on a total parameter of chemical pollution is lead.
