Influence of some geoecological factors on destruction of concrete constructions of Cheboksary hydroelectric power plant
The short characteristic of engineering-geological and hydrological conditions of the grounds of concrete constructions is given. Factors of formation of ecological conditions in a benthonic zone of a water basin of Cheboksary hydroelectric power plant are analyzed. Dynamics of change of activity and number of microorganisms in water and bed deposits of a water basin is considered. Results of specialized shooting in dry footway about a condition of concrete of a hydroelectric power plant building of and an overflow dam in 2010-2011 are stated, the comparative estimation of microbiological activity which promotes development of the vigorous activity of biocorrosion of concrete and metals is spent.

Evaluation of a breaking of plant communities exposed to technogenic load with space monitoring method
- Authors:
- D. S. Korelskii
The basic principles on the use of satellite images of different resolution to asses s the state of natural soil and plant communities with severe human impacts, primarily atmospheric. The main features include load manmade the atmospheric accumulation of pollutants in the snowpack, changes in the state of soil and reduction of the projective cover of trees and shrubs as compared with background areas with negative long-term dynamics.

Estimation of the condition of the soil-vegetative complexes having stress at atmospheric impact
- Authors:
- D. S. Korelskii
- M. A. Chukaeva
The main research objective was monitoring and assessment of terricolous and plant cover condition in forest ecosystems influenced by industrial pollution by the Severonickel Industrial Plant, which impact zone covers 1.4 thousand sq. km. During an expedition to the Murmansk Region samples of upper soil layers and plants were taken in areas directly affected by atmospheric impact from OAO Severonickel both at various distances from the plant and in background territories. This will help to determine the overall degree of soil contamination at various distances from the plant as well as distribution of heavy metals accumulated in various soil layers and a complex estimation of adverse impact on soil cover and various plant species.

About origin of acidification of «blue» lakes in the aria of humid climate
- Authors:
- I. L. Kuzina
- O. N. Yakovlev
«Black» lakes are widely widespread in the area of humid climate. Their waters contain many humic matters and cut-in iron, therefore have different intensity with a brown – yellow tint. On this background lakes meetings lakes with clear colourless water considerably stand out. Due to mass development on the bottom of these lakes of dark blue-green aigae (cyanobacterias) water in them is of greenish-blue tint («blue» lakes). In the course of life, these microorganisms consume dissolved organic substances and sulfates and produce in the daytime – oxygen, and at night – hydrogen sulfide which reacts with dissolved iron in water. This transition increases the acidity of the pyrite in the lake waters and is also accompanied by acidification of the water. Periodic formation of hydrogen sulfide is the cause of «acidification» of lakes. In addition, it leads to precipitation of dissolved iron in the form hydrotroilit. It’s not the «acid» rains that are only an additional supplier of sulfates in the lake under consideration but the activity of specific groups of microorganisms cyanobacteria mats that considered is the main cause of «acidification» of lakes (low pH). These processes should be taken into account when considering the anthropogenic impact on the state of water objects.

Justification of the necessity of forming a protective screen for dumping waste dumps in the development fields
- Authors:
- M. A. Kulikova
The negative impact of mining on the environment is increasing annually. This is due to an objective increase in consumption of material resources by humanity. In today's mining output of finished goods is less than 10%, the rest of the volume represented by mining and processing wastes, which are assigned for the storage of hundreds of thousands of hectares of land. Chemical waste, as a rule, contain components which, being outdoors and being exposed to the impacts of climatic factors, can be transformed into new compounds, and to migrate hundreds of kilometers from the source.

Primary forecasting method in the problem of reducing loads on landscape under planning large-scale geological and ecological surveys
- Authors:
- I. B. Movchan

The method is based on the formal lineament decoding the half-tone field of brightness of multispectral satellite slides. It includes the procedures of point of extremum tracing, rotation and generalization with using angular and dispersion criteria. The result is the set of structuretectonic maps of different level of generalization. These maps are additionally processed for discovering the factors of structural control of ore objects of different ranges. Here the leading criteria are the periodicity, the areas of discordant relationship, and the singularities on the branches of logarithmic spirals. Such approach admits the forecast implementation with the information about reference objects and without this one.

Complex of geochemical studies in developing of Sibai chalcopyrite deposits are conducted. The peculiarities of the chemical composition of natural waters, the specificity of technogenic migration of ore elements in river sediments and soils, as well as the involvement of heavy metals into the biogeochemical cycle are established. The extent of transformation of natural geochemical processes in technogenesis is revealed. Approximate dimensions of man-made streams and scattering halos of ore metals are determined. The recommendations at reducing anthropogenic migration of elements are aimed.

The ecological negative influence reduction ways on mining regions
- Authors:
- S. I. Fomin
- A. A. Faul
Coal mining can result in a number of adverse effects on the environment. Open cast coal mines leaves areas of land that are no longer usable and leaves a scarred landscape with no scenic value. Rehabilitation can mitigate some of these concerns. Mine tailing dumps produce acid mine drainage which can seep into waterways and aquifers with consequences on ecological and human health. Subsidence of land surfaces due to collapse of mine tunnels can also occur. During the mining operation methane, a potent greenhouse gas and a constituent of fire damp, can be released. Wherever it occurs in the world, surface mining of coal completely eliminates existing vegetation, destroys the genetic soil profile, displaces or destroys wildlife and habitat, degrades air quality, alters current land uses, and to some extent permanently changes the general topography of the area mined.
