Annotation: the article reflected the state of the components of the environment and the quality of
agricultural products in the context of increased anthropogenic load. The purpose of the study was to examine
the accumulation of heavy metals in the components of the environment and patterns of their migration in
agrobiocenosis of Sterlitamak district of Bashkortostan Republic. The study on the content and distribution of
heavy metals in environmental media and products of plant and animal origin in the territory of Sterlitamak
district of Bashkortostan Republic. The species specificity agrophytocenosis plants in the accumulation of
heavy metals.
Key words: soil, heavy metals, agro-industrial area, content background, concentration, excess.
Natural and climatic conditions, the presence of minerals in the Bashkortostan Republic led
to its powerful industrial potential.
More than four thousand industrial enterprises and organizations are sources of emissions,
the fleet consists of about 1,2 million. Units of motor vehicles [16].
Along with the enterprises of metallurgy,
mechanical engineering, power engineering, oil
refining, chemical industry, the construction industry in the Republic operates a large network
of oil and gas pipelines, resulting in increased human impacts on the biosphere components,
resulting in a complex association of elements in the soil and living organisms, altering their
functional properties depleting potential of assimilation and adaptation reserves.

CONTEMPORARY PROBLEMS OF SOCIAL WORK
The leading industries are the oil-producing and oil-refining industry,
chemical, petrochemical
and mechanical engineering.
In connection with the polytypic character of anthropogenic impact, manifested in the
Russian Federation, including the Bashkortostan Republic, the need for regional study of the
elemental composition of all parts of the food chain, especially the distribution patterns
of elements in agroecosystems, bordering
the industrial centers, where crop production
economically and livestock due to close proximity to the consumers and processing
enterprises.
Thus the area of the Republic is the agricultural Sterlitamak District, characterized by the
close proximity to the sources of pollution, including heavy metals.
A list of the most characteristic of heavy metals, scattered as a result of anthropogenic
impact on the territory of the district, is presented in Table 1.

In Sterlitamak city, which is the administrative center of the district there are large
chemical industry enterprises («Soda», «Caustic», «Rubber») and mechanical engineering, the
company building industry, fertilizer plant. Anthropogenic pollution Ni, Cr, Pb, Zn, Fe occurs in
the production of the following products: the cathode polyelectrolytes, metal oxide anodes
for
electrolytic process, dry mixes, cement, machine tools, pipe layers, bulldozers, pile driving,
drilling and exploration equipment.
The observations of air quality in Sterlitamak city held on 5 stationary observation network
for the state of the station environment.
The stations are divided into «urban background», located in a residential area, «industrial»,
located near the business and «auto», mounted near the highways and in areas with heavy
vehicular traffic.
The data obtained by the monitoring stations, show that in the period from 2008 to 2012 there
was a decrease in gross emissions into the air of Sterlitamak city (Table 2).
A great contribution
made by the electricity companies of more than 20% in air pollution.

In 2012, the city heating plants in the applicable fuel decreased the proportion of fuel oil
and industrial plants gas cleaning plants destroyed more than 90% of harmful substances in
the exhaust air, thereby reducing their emissions. At the same time it increased the amount
of emissions from vehicles due to increased freight volume and fuel consumption.
