In the model experiments we studied the effect of combined action of chemical pollutants (PbO 1,000 mg / kg oil 5% by weight of soil) and microwave radiation (SHF radiation) with a capacity of 450 and 800 W (duration 1 minute) on the enzymatic activity, the number of microorganisms and indicators of phytotoxicity of an ordinary black soil. We found that the combined effect is systemic, rather ...

The residual amounts of the pesticides in the coastal water of the Azov Sea were studied in spring seasons of 2009-2011. The concentrations of the pollutants were determined and the degree of their danger for hydrobionts was assessed. The concentrations of the pesticides diluted in the water of the Taganrog Bay and the eastern Azov Sea are shown to be lower than the maximum admissible concentr ...

In the article, we have studied the effect of lead contamination, an alternating magnetic field, their combination on such groups of soil microorganisms, as ammonifying, amylolytic, nitrogen-fixing bacteria, and micromycetes. The pollution had a significant and different effect on the number of soil microorganisms. The nature and extent of this effect varied depending on the level of impact of ...

Oil products are among the most widespread pollutants of objects of environment. Near Maikop in 2008 the large center of black oil pollution was formed. This site became the range for studying of consequences of black oil pollution of soils and water objects under natural conditions. In the real work stages of a recultivation of the soils polluted by fuel oil on a site in Maikop are described. ...

In the article we consider the influence of agricultural technologies of cultivation of winter crops on existence of various forms of heavy metals in an arable layer of earth in the conditions and their accumulation in grain production. The gross content of compounds of copper in an arable layer of black leached soil is above background values (maximum concentration limit 1,5-1,7), a share of ...

The anthropogenic interference plays more and more increasing role in modern ecologic paradigm. Adjusting this role to the studied region, it is defined by the socio-economic conditions being formed in our country. The rate of construction in the resort zones of the Krasnodar region is sweepingly rising. In spite of the high therapeutic-recreational capacity of the region, this tendency is lea ...

The reliability of work of the technical systems significantly influences the technological losses of manufacture process. During the counting the availability ratio of the technical system it is recommended to take into the consideration implicit as well as evident breakdowns of all separate components of the whole object. There is a formula for counting technological losses depending on the ...
