There wasconsidered pressing issue of efficiency upgrading and cost saving of fine grain concrete in the process of manufacturing small piece wall materials with the use of man-made raw materials as bottom-ash mixtures of CHP plants. There were reported results of bottom-ash mixtures investigations and developed on its base compositegypsum binders (CGB) for fine grain concrete. There was examined microstructure and morphology of floured mineral supplements from bottom ash and fly ash, prospects of these components usage as filler in the composition og CGB. There was investigated properties of fine concrete and concrete mixtures for given CGB, remold ability, porosity, density, structural behavior and deformation properties. There was empirical proved efficiency of complex usage of local raw materials, including man-made raw in the process of manufacturing f CGB and fine grain concrete on its base.

In the design of toxicity reduction system of emissions the main factor for forecasting of system lifetime will be the right determination of crippling external load that leads to full failure of system’s elements. There was considered system of manufacturing from structural inhomogeneous material, containing abnormalities of type cracks. There was studied mutual interaction of crack with the field of circular holes in plate. There was considered one case, when size of crack is more than radii of punched holes. There was obtained dependence of average values of critical load from disposition of micro pores and level of material damage, calculated value of crippling external load, that leads to cracks contraction. There was established that at disposition of micro pores in front of micro cracks, the average fracture strength decreases by 30 %, at disposition micro pores over or under micro crack the average fracture strength increases by 46 %. Under distributed porousness fracture strengthdeclines. Offered technique allows forecast life span of emission reduction system during the stage of its design, taking into account mutual interaction of crack with micro defects of material.

There was demonstrated a possibility of preparation of encapsulating materials on the basis of polyurethanes and solid waste of petrochemical manufacturing – alumina (alumina gel), silica gel, zeolites and cement, used as fillers. There was investigated particle size distribution depending on filler type, defined average grain diameter and polydispersity index of filler. There was defined influence of nature and quantity of waste on viscosity of original semi polymer, used for synthesis, as well as alteration of wetting properties of polyurethane composition in time and depending on tipe of filler. There were given results of physical testing of received materials. Taking into account summation of explored data for each filler was established optimal degree of extension. There was developed conceptual technique of polyurethane composites preparation with the use of investigated manufacturing waste.

There was considered arsenic waste’s pollution issue from mining and processing industry concerning municipal formation “Svirsk Town”. There were given characteristics of waste disposal facility. There was considered mechanism of arsenic and heavy metals deactivation, consisting in chemical bonding with hardly soluble compounds. There were presented the main stages of arsenic pollution source’s mitigation within a framework of Federal target programme “National System of chemical and biological safety of Russian Federation” (2009-2014).

There was made analysis of NPP Fukushima accident, offered considerations, which don’t reflect in existing literature. There were considered issues of accidents qualification, indicated on importance of detail and accessible descriptions each of its. Special attention is given to analysis role and meaning of safety culture, development of concept of echeloned defence and principal conclusions, that could be made from previous accidents for ensure security of operating conversion nuclear reactors NPP. Given considerations are directed on promotion of security NPP, increasing of efficiency of sector work and written for consequent discussion and supplement by such professionals, whom entrusted development of programmes of measures on further improvement of securing and regulation of safety during nuclear energy usage.

There was proved that, at this time, chlorinating agents are the most effective in the process of water treatment, and possessed by long acting, that could not assure other methods of disinfection. Nevertheless, in connection with of higher risk of molecular chlorine usage as reagent, there was arise necessity of investigation of alternative methods. One from the most advanced and optimal method of drinking water disinfection was recognized method of water purification by means of sodium hypochlorite. In connection with generation during water disinfection by chlorinating agents of different Organohalogen compounds, some of which are fairy toxic, was carrying out analysis of by-products in water, treated by sodium hypochlorite. There were presented results of benchmark study of Organohalogen substance’s’ mixture composition, producing during the disinfection of water by chlorine and sodium hypochlorite, conducted with use of gas chromatography mass-spectrometry.

There were carrying out investigations of quantitative variables of harmful substances during manufacturing of casting mold and foundry mixes. There were given determinations of environmental friendliness of technological process and foundry mix. There was offered simplified technique of determination of foundry mix’s environmental friendliness with the aid of sample’s mass loss during high temperature heating and total value of maximum allowable concentration.

Inaccuracy of solutions in the field of ecological safety in many cases is linked with impossibility encompass thousands and millions signals, supplied by industrial facilities or objects of ecological interests, necessity of orientate on average readings, losing relevant information. We could escape such loss, using methods of visual verification, i.e. presentation of laboratory data’s array in view of graphs and diagrams. In developed economy this reception is a part of data processing and administration of “Big Data”. There were offered instruments of visual qualimetry, such as control cards, scattering plots, block diagrams. Through the examples of analysis data array on measuring of quality indicators for natural and waste waters, demonstrated efficiency of these instruments, allowing “squeeze” or even attain a “new” information, which “as there were no” under other its representation.

By means of Earth Remote Sensing was investigated area of Klyazma Resort in the lot of gas pipe line Pochinki – Gryazovets, operated by company LLC “Gazprom transgaz Nizhny Novgorod” Ivanovskoye Local Gas Transmission Distribution Facility. During processing of multispectral image of Landsat 8 satellite were calculated numerical data of indices NDVI, NDWI and VARI, selected under assay man-made impact of linear industrial object on environment.  On the basis of vegetation index analysis, represented as digital maps, there was carrying out assessment of man-made impact of investigated section of gas pipe line on vegetable life of special natural area protection. According to the data of analysis of satellite imagery of gas pipe line routing, made conclusions on low level of impact of operated industrial object on environment.
