EVALUATION OF CHEMICAL CONTAMINATION AND DEGRADATION OF SOILS IN THE INFLUENCE ZONE OF VAKHITOVSKY FIELD [№ 5 ' 2016]
Orenburg region is rich in minerals, the main ones are gas and oil, in its depths explored more than 2 500 deposits of 75 kinds of minerals, and in terms of reserves and mining region is among the leading group of regions of Russia, this industry has a significant impact on environment. Soil pollution by oil and oil products refers to a very popular type of negative anthropogenic impacts, especially in the industrial regions of Russia. A key element in the chain of the environmental impacts of oil pollution is a change in the species composition of vegetation and reducing its productivity until the complete destruction of all plants in the contaminated area. Investigated the problem of soil contamination in the zone of influence Vakhitovsky deposits (Orenburg region). Vakhitovskoe oil field is located in Perevolotskaya district, 32 kilometers north of the regional center Perevolotskiy.Mestorozhdenie was commissioned in 1995, is currently 20 wells listed in the mining fund. Soils were analyzed for the content of acid impurities, metals, benzo (a) pyrene, petroleum and pH. They were calculated: the concentration of pollutants, concentration ratio relative to the background impurities values in soil and soil contamination indicator chemical profiling using the method. Identify priority among the impurities of acidifying substances and metals. A ranking by total chemical pollution of soils, which showed that issleduyumuyu contact area at a distance of 1 500 meters from the source of pollution can be attributed to the zone of ecological emergency. Identify indicators phytotoxicity of soil from which it follows that the soil in the zone of influence in the fields Vakhitovsky rasstoryanii up to 1 500 meters are highly degraded.

ENVIRONMENTAL CHARACTERISTICS OF VARIOUS FUNCTIONAL ZONES IN ORENBURG [№ 10 ' 2015]
City human environment includes both natural components — air, water, vegetation, soil and fauna and artificial human material elements, which are surrounded by and in contact with which flows the livelihoods of people. In the course of human life changes more natural components of the environment of the city, giving rise to many environmental problems. The city is one of the kinds of social and spatial organization of the population, which emerges and develops on the basis of the concentration of industrial, scientific, cultural, administrative and other functions. In a compact footprint of industry, infrastructure and the population has significant social effect, giving people greater access to the self-realization, health, social services, ways of spending free time. But on the other hand, high population density and concentration of industrial facilities, along with a variety of factors arising from economic activity (noise, vibration, etc.) in a limited area, form the human environment, which by its subject-spatial, physical, chemical and biological parameters and other indicators are fundamentally different from the originally genetically adapted.

ECOTOXICOLOGICAL PROFILES OF SOIL QUALITY IN THE ZONE INFLUECE AKTOBE FERROALLOY PLANT [№ 10 ' 2015]
The modern enterprise is a complex metallurgical industrial complex, including a variety of shops, and sometimes individual plants, which greatly degrade the environment. All the known processes, metal production and subsequent redistribution accompanied by the formation of large amounts of waste in the form of harmful gases and dust, slag, sludge, sewage water, containing various chemical components of the scrap, slag, battlefield refractory debris and other emissions that pollute the atmosphere, water, and earth surface. The main activity ofthe Aktobeferroalloys plant(AFP) — production offerro-alloysof different grades. It producesferrochrome,ferroselikohrom, chromium metal, as well asadditional products: lime,carbon dioxide, sodium silicate, calcium carbide,refractory products, rubble, ferropyl, ilmenite concentrate, rutile-zirconproduct.Are minedilmeniteis buildinga factoryto producezirconand rutile.

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.

ENVIRONMENTAL ASSESSMENT OF SOIL WITHIN THE ENTERPRISE OIL PRODUCING INDUSTRY [№ 10 ' 2013]
The analysis of soil samples of the area adjacent to Kapitonovskoye field of "Yuzhuralneftegaz" for harmful contaminants and ranking of the study area for ecological distress on the basis of the indicators of chemical pollution.

CONTENT OF HARMFUL IMPURITIES IN PRECIPITATION AND SOIL AREA "BUZULUK MECHANICAL PLANT" [№ 10 ' 2012]
The analysis of samples of precipitation and soil area adjacent to the JSC "Buzuluksky Mechanical Plant", the content of impurities and ranking study area for ecological trouble in terms of chemical contamination of sediments and total index of soil contamination. It is established that the priority of the impurities is hydrogen — ions, sulfate ions, calcium ions. From the values of the total index of chemical pollution of soils, it was found that the area in the SPZ boundary south-east of "BMP" refers to an area where critical loads, while the rest of the territory adjacent to the JSC "BMP" — the territory of the relatively satisfactory situation.

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.

EVALUATING MOTOR TRANSPORT SHARE IN AIR POLLUTION WITHIN THE CITY OF ORENBURG [№ 1 ' 2001]
Ecological problems caused by motor transport have become especially urgent in Russia for the past ten years. In 1998 the automobile part of Russia accounted for 23.7 mln vehicles including 18.8 mln cars, 4.26 mln lorries and 627000 buses with growth rates of 5.3% - in 1996, 9.2% - in 1997, 5.2% - in 1998. Ecological problems proved to be especially urgent in large industrial centres. Vehicles run in the country do not meet modern European toxicological norms and eject much more noxious substances than their foreign analogues.
