There was showed that energy density, generated by membrane cell, substantially increased with increase of solution mineralizing.

There were considered negative applications of dusty materials’ tailings influence on environment from Norilsk Industrial Region. There are offered methods of control negative applications on environment by means of tailings’ dusting surface’s constraint. There were tested for constraint of dusting surfaces physical fixers or chemical bounding, such as bitumen emulsion, styrene acrylic dispersion, liquid glass. There was demonstrated that main disadvantages of these ways of dusting tailings’ constraint are use of expensive materials and possibility of work performance only at warm and dry periods. There was reasonable for dust control from tailing ponds use molten sulphur, i.e. secondary product of sulfide ores processing. There were carrying out investigations of main performance parameters of protected covering.

There was considered a possibility of extraction industry\s waste use in the nature of ultrabasic rocks (dunites and perlites) as additive in the process of structural ceramic manufacturing. There was demonstrated that obtained materials are possessed good physical and mechanic indices. There was specified that addition in the charge material’s composition of dunite and perlite’s fine fraction allows decrease ceramic materials’ burning temperature. Under plastic shaping at 1100 oC and additive quantity up 50 % specimens meet GOST requirements. Under semi dray shaping and the same quantity of additive specimens of ceramic meet GOST requirements at more low burn temperature. Carried studies demonstrated a possibility of patch ceramic brick’s obtaining, as well as façade ceramic of high quality and low cost of production through use of extraction industry’s waste.

There was demonstrated that conception on layered atmospheric structure, conditioned by physical properties difference, postulated in AUSD-86 (All-Union Standardized Document) as basic model for hazardous substances concentration’s calculation in open air, for all sources of pollution, irrespective from its altitude and origin of manufacturing process, appears incorrect in respect of ventilation source of emissions, with height up 35 meters and temperature of emission, differentiated from ambient air temperature by 5 … 12 oC. There was specified that location of maximal concentration of hazardous substances is defined by kinematic range capability of free turbulent jet, linked only with kinematic pattern of this jet and velocity of open air’s main stream.

System analysis of risk exposure factors’ modern spectrum of physical origin within the Northern Eurasia allows non-biased evaluate resource quality of the geological area on the exposure levels of leading natural and man-made geophysical factors of environmental risk for the purpose solving problems of adjustment economic specialty of regions for the improvement sustainable development’s program of Russia in the light of Rio+20 Earth Summit’s decisions. There were considered natural geophysical factors of environmental risk, conditioned by radioactive decay of elements of natural radioactive family of uranium, thorium, as well as Potassium-40, and which determined the main part of population’s physical stresses. There were described physical factors of man-made genesis’ environmental risk. There was given classification of radionuclides contamination for earth surface territory. 

There was investigated the state of environment as one of main factor, defining health and living standard of population. The problem of water management and environment protection linked both natural features of region and in significant degree with engineering and economic activities. The investigation of environmental and hydrogeological features of building of ground waters and surface waters of Oryol Oblast has great significance in respect of increasing need of ground water sources use for problem of water use solving, because at present this problem is one from great environmental issues in region.

At present there is need application of new advanced techniques for continuous remote control of industrial facilities’ construction parts’ state, which are nearby water bodies. Monitoring data allow timely realize preventive coast protection measures by way of  building capital waterworks and not allow emergencies of natural and man-caused character, negative environmental consequences on the territory of industrial facilities. Results of deformation monitoring could be aid in definition of priorities of investments for building of these coast protection objects. There is important state task in the conditions of financial resources scarcity.

There was discussed classification of petroleum products’ losses at fuel filling station by the kind of losses, sources of it origin, types of processing. There were calculated emissions of pollutants into air, occurring during fuel tank filling and pumping fuel from gas servicing truck into store holder. There was calculated one-time maximum emission and determined emissions composition for the operation of oil products’ pumping into store holder as well as during fuel tank filling.

Heating oil, which is heavy fuel, presents severe environmental threat in the event of its leaking into environment. Knowledge of given kind of fuel’s properties is essential condition of its combustion issues. In the article there was analyzed essential properties of heating oil, presented methods of funnel viscosity detection (GOST 6258), moisture content (GOST 2477) and density (GOST 3900).
