Algorithms for calculating the radar characteristics of radioactive atmospheric emissions
A structural scheme of the algorithm for calculating atmospheric emissions from nuclear power plants is presented. The additive model of the effective scattering area of the emission takes into account different components of the process: air ionization by radionuclides, turbulence and thermal inhomogeneities, aerosol particles, tracks of alpha-particles and meteorological formations of natural origin. Input data for calculations are meteorological data, radar parameters and interference situation in the region. As a result of calculations the field of spatial cross-sections of NPP emission into the atmosphere can be obtained and spatial characteristics of technogenic and natural meteorological formations can be specified (using radar data).

Decontamination of industrial effluents containing aromatic compounds using sound chemistry
- Authors:
- A. I. Kiprianov
The object of the research is industrial effluents of chemical plants containing aromatic compounds (phenols). The aim of R&D is to develop a scientific basis and method of neutralization of highly toxic aromatic compounds under the influence of ultrasound. The chemical effects of ultrasound in aqueous medium are observed under conditions of nonlinear vibration propagation and are associated with the phenomenon of cavitation. Under the influence of intense alternating vibrations, the liquid ruptures with the formation of a cavity, the development of which leads to the appearance of radical highly reactive particles. In the case of water such particles are hydrogen atom and hydroxyl radical. The hydroxyl radical is capable of oxidizing almost all known organic compounds; being a typical electrophile, OH* easily reacts with molecules containing an aromatic ring (chlorinated lignins and their fragments, chlorophenols, phenols). As a result of the interaction, the R-groups in the side chain are replaced with hydroxyls; the cleavage of the aromatic core leads to the formation of carboxylic and hydroxycarboxylic acids. Thus, the practical application of ultrasonic vibrations (USV) leads to detoxification of industrial effluents containing organochlorine compounds without introducing additional chemical reagents into the system.

Analysis of radiation risks for the population of the Urals region using threshold and threshold-free models
- Authors:
- A. V. Kruzhalov
- M. V. Zhukovskii
- A. V. Pavlyuk
The main ways of radiation risks assessment are considered: linear threshold-free model and practical threshold model. New approaches to selection of radiation risk assessment threshold based on comparison of man-made exposure doses with lifetime exposure doses from natural radiation sources are proposed. The threshold of risk assessment for exposure to radon daughter products equal to 30 Bq/m3 has been proposed. Using both threshold-free and threshold models the estimates of radiation risk for the population of Sverdlovsk region exposed to natural and anthropogenic sources were made. It is shown that the contribution of technogenic training is much lower than that of permanent radiation factors - radon and medical diagnostic irradiation.

Physical and chemical substantiation of decontamination of the 5th district of Vasilievsky Island in St. Petersburg from strontium-90 contamination
In order to calculate parameters of purification of soils from 90 Sr the exchange isotherm of Sr 2+ Ha cations of iron (III) between Cambrian clay and aqueous solution with pH = 3 was studied. Isotherms of joint cation adsorption in joint presence are described by the Langmuir equation. Using the values of the Langmuir constants, the Gibbs constant and energy of ion exchange equal to 15 and -6.7 kJ/mol, respectively, were calculated. These values coincide with those calculated from the individual adsorption isotherms of Sr 2+ and Fe (III) cations on clay. According to the obtained constants it is possible to deactivate soils from 90 Sr contamination by means of ion-exchange washing with solutions of iron (III) salts, which is confirmed by field studies in the 5th quarter of Vasilievsky Island. The performed technical-economic assessment of the decontamination of the 5th quarter shows that the washing cleaning will give an economic effect of about 150 million rubles compared to soil removal and burial.

- Authors:
- L. P. Alekseenko

Ecological and biogeochemical monitoring of the state of the landscapes of the Tsemesskaya Bay studied changes in the content of a number of metals in the most common algae. Sampling was conducted annually in spring and summer. To increase the reliability of the data, information was processed on a specially compiled map of aquatic geochemical landscapes. During the period under study the highest concentration of the majority of studied metals in algae was registered in 1998. This is most likely due to previous pollution of the bay, when almost all enterprises of Novorossiysk were still operating. Minimum concentrations of metals in algae are typical for 1999. In 2000 metal concentrations started to increase again.

A unified methodological approach to the analysis of complex mixtures of volatile organic compounds in various media (air, water, soil), implemented with the use of universal methodological and instrumental bases, is substantiated. The main analytical method is the highly sensitive multivariate capillary gas chromatography in combination with other effective processes (gas extraction, sorption concentration, thermal desorption, cryogenic focusing etc.) applied in the operational line for sampling, sample preparation, pulsed sample introduction etc. Based on the metrological studies of the proposed basic technique for the analysis of multicomponent impurities (27 compounds in air samples) the techniques for measurement in air and water samples of mixed substances: gasoline, kerosene, white spirit and solvent oil were developed. The suggested principles of universality and unification of the operating series provide intensification and cheapening of their ecological control and monitoring.

The main share of accidents on oil pipelines, leading to serious negative environmental consequences, is associated with corrosion destruction of pipes. The most difficult task is corrosion protection of the welded joint of the pipes. The use of electric pulse technologies for fixing the elements of anticorrosive protection in butt-end areas of inner surface of pipes allows to increase the corrosion resistance of a pipeline and to decrease the expenses for its installation. The results of the conducted research allowed developing technological processes of fixing aluminum alloy protectors in pipes by means of magnetic-pulse welding, magnetic-pulse and electrohydropulse pressing of thin-walled stainless steel bushings into near-end sections of pipes, as well as creating the necessary equipment for implementing these processes.

- Authors:

Nonlinear mechanisms of multi-year fluctuations of the Caspian Sea level are described. It is shown that taking into account the dependence of the evaporation layer from the surface of the Volga basin on the soil moisture content and the evaporation layer from the sea surface on its level leads to a fundamentally new (chaotic) mechanism of oscillations and the appearance of several levels of gravity. It is noted that the stochastic Fokker-Planck-Kolmogorov differential equations have a stationary bimodal level probability density. It is established that the random process characterizing sea level fluctuations at nonlinear dependence of evaporation rate on these fluctuations turns out to be non-Gaussian. The transitions induced by "noise" caused by nonlinear evaporation processes are described. A new nonlinear stochastic model of Caspian Sea level fluctuations based on predicted physical effects is proposed.

- Authors:
- M. A. Sereda
The system of integrated environmental monitoring of objects of high environmental risk in the exploration and operation of oil and gas wells is proposed. Outlined the methodological basis of observation, assessment and control over the state of the natural environment components in the impact zone of oil production enterprises. It was revealed that for reliable determination of the level of environmental hazard of oil and gas industry facilities requires a detailed study of the state of the landscape before the construction of wells and the characteristics of the processes that create a technogenic load on the environment. In order to prevent and eliminate the consequences of the negative impact of oil and gas industry facilities a number of new technological solutions are proposed at different stages of the field operation (for example, at the stages of prospecting, exploration and development of hard-to-reach deposits to reduce the technogenic load of cluster horizontal wells with a waste of up to 500 m from the vertical). In cases of emergencies we offer technologies for localization of oil spills, processing of oil-contaminated water and soils, recultivation of disturbed areas, utilization of toxic oily waste.

New methods of remote determination of the thickness, spill area and type of oil film on the water surface using fluorimetric lidar have been developed, providing monitoring of oil films in the thickness range from several micrometers to several tens of micrometers from a moving ship and a low-flying aircraft. The ultrasonic express-method has been developed for express measurement of films with thickness more than 100 micrometers. In realizing this method, measurements are made in real time by probing the water surface from a moving ship using an ultrasonic source and receiver placed under water. The efficiency of these methods has been studied experimentally in laboratory conditions with the use of different types of oil spilled on the water surface. The principles of constructing a biotechnical system for assessing the current state and forecasting the quality of water environments polluted by oil products are considered.

The integrated atmospheric pollution index (API) of St. Petersburg ranges from 6 to 14, while an API index of less than 5 is considered the norm. Each year, more than 260 thousand tons of pollutants are emitted into the atmosphere of the city. According to the proposed methodology of the Ministry of Transport of the Russian Federation for determining the mass emission of pollutants into the air by motor vehicles, the original data should be obtained with an automated television and computer complex using modern information technology, which is much cheaper and more efficient than the currently used methods. Studies show the great efficiency of the complex, both in terms of the speed of obtaining data for the analysis of atmospheric pollution and the sufficient accuracy of these results.

Intensive development of underground space in large cities causes the necessity of its economic assessment taking into account environmental factors. Development of methodological bases of ecological and economic evaluation of underground space requires analysis and consideration of its features as a natural and economic resource. Urban underground space is formed under the influence of two environments (urban environment and the subsoil) and has the properties inherent in both. Features of the urban environment are a large concentration of people, the specificity of the use of space and the high variability of conditions over time. The subsoil is characterized, as a rule, a high density of the environment and isolation from the surface.

Quantification, normalization and regulation of multifactorial anthropogenic impacts on freshwater ecosystems
Methods for quantitative study, assessment, rationing and selection of measures for regulation of multifactorial anthropogenic impacts on ecosystems of freshwater reservoirs and watercourses have been developed. Reaction of biota to influence is estimated by a condition of macrozoobenthos as the most sensitive bioindicator, and the influence itself is estimated by the special indicator taking into account effect of interaction of factors. The regulation of multifactorial impact is based on identifying its maximum permissible level, which does not cause irreversible changes in macrozoobenthos. Regulation of the impact is aimed at reducing it to the maximum permissible combinations of interacting factors to achieve a safe level of their joint biotic effect.

Analysis and evaluation of safety enhancement of low-level waste disposal in the Lower Cambrian blue clays of the western part of the Leningrad Oblast
- Authors:
- R. E. Dashko
- A. A. Eremeeva
The composition, structure, physical, physical-chemical, and mechanical properties of blue Lower Cambrian clays in the western part of the Leningrad Oblast have been analyzed. The blue clay formation is considered as a medium for the disposal of radioactive waste near the Koporje settlement. Complex analysis and assessment of the conditions of formation and transformation of blue clays under the influence of natural and anthropogenic factors has shown that prolonged radioactive irradiation of clay strata leads to an increase in the disintegration of clays, reduces the resistance to shear and deformation properties indicators of the activation of microbiological activity, which are considered as a negative factor. Changes in clay properties contribute to the disturbance of hydrodynamic conditions and increase the risk of aquifer pollution. Nine criteria for safe operation of underground storage facilities based on the study of engineering-geological and geo-environmental factors are proposed. Long-term safety of operation of underground storage facilities in clay strata should be based on the multi-barrier concept of environmental protection.

- Authors:
- V. S. Lesovik
- V. V. Strokova
A crystallochemical approach to the problem of choosing raw materials for the production of inorganic building materials has been proposed and substantiated. Crystallochemical parameters of substances of the following stages are proposed to be used as the main criteria in the selection, design and development of the production technology of building materials: genesis of raw materials, technogenesis, operation of building materials. The dependence of the formation of technological properties of materials on the degree of crystallinity of the initial minerals has been revealed. The formulated principles of choosing the rational area of using natural and anthropogenic raw materials in the building materials industry, based on the crystallochemical features of the main rock-forming minerals, allowed to develop effective fine-grained concretes using wastes of wet magnetic separation of ferrous quartzite and the technology of their production.

Analysis of the constitution of mineral individuals and aggregates in order to create a basis for reducing the loss of useful components and environmental impact assessment in the development of ore deposits
The main objects of the research were the deposits of noble and non-ferrous metals of the Urals, Siberia and Novaya Zemlya. It is shown that the establishment of a pomineral balance of distribution of chemical elements in ores, the study of variability of the material composition and stereometric features of ores in the geological space is extremely important to solve the problems of rational use of ore deposits and the prediction of environmental consequences of their development. When assessing the environmental impact of the deposits involved in the exploration and exploitation, both the regularities of distribution of toxic elements and minerals in the volumes of ore bodies and fields, and landscape-geochemical conditions determining the factors of migration and accumulation of these components after their extraction on the earth surface should be taken into account. For geological-economic and environmental forecasting it is necessary to accumulate materials on the distribution of impurity elements, sometimes not playing a role in assessing the industrial importance of deposits, but leading to the emergence of various man-made geochemical anomalies in areas of exploration and mining operations, as well as the formation of man-made deposits in places of waste storage of concentration plants and metallurgical plants.

Environmental monitoring of sulfide-containing technogenic massifs
- Authors:
- M. A. Pashkevich
- Yu. V. Shuvalov
- E. V. Eldina
To date, the total amount of rock mass displaced on the planet exceeds 100 billion tons. The result of such impact is the formation of man-made massifs - geological structures, composed of rocks or sediments of anthropogenic genesis, which differ in their composition (chemical, granulometric, bacteriological) and properties (physical, mechanical, filtration, sorption, etc.) from the host rocks. Shapes and sizes of man-made massifs are determined mainly by technological processes. In areas of sulfide-containing technogenic massifs, due to waste in an oxidizing environment, the formation of acidic drainage water occurs, the processes of formation of which are complex and nonstationary, which greatly complicates the monitoring of the state of the massifs. Development and application of a new method of acid-alkaline balance, consisting in determining and comparing the acid potential and neutralization potential, formed by rock or waste, allows with high expressiveness and accuracy to monitor the situation in areas of sulfide-bearing man-made massifs, significantly reduces the time for laboratory research.

Earthquake-proof structures of mine workings during the development of shock-hazardous deposits
On the basis of the laws of changing the parameters of the dynamic stress field during the interaction of seismic waves with the mine workings the requirements to the seismic resistant armoring of mine workings in the zones of rock bumps and mass explosions are formulated. The operability of traditional types of anchors under dynamic loads is evaluated. The optimum design of fortification of excavations in the shock-hazardous areas is a combined support from steel-polymer or reinforced concrete anchors with a solid filling of the boreholes with a fortifying composition enhanced by piles of long (up to 3.5 m) reinforced concrete anchors in the place of wave exit on the contour of the excavation. The length of the anchors is chosen according to the tensile stress zone overlap.

Measures for the use of anthropogenic metallurgical waste in the production of high quality alloys are proposed. The relationship between the amount of casting wastes in the charge with the type and features of temperature dependences of physical and chemical properties of the melt has been found. As the amount of waste increases, the critical temperatures increase. The use of high-temperature treatment of the melt can significantly improve the quality of castings from heat-resistant alloys containing a significant amount of casting man-made wastes in the charge.

- Authors:
- V. P. Zubov

The analysis of domestic and world practice of development of technogenic resources shows that their development can serve as an additional source of obtaining non-ferrous and precious metals for mining enterprises, as well as contribute to the reduction of the harmful effects of toxic substances on the environment and the return to the economic turnover of previously withdrawn lands. For a number of mines, the development of man-made deposits is a priority source of existence of the mining enterprise. However, the practical development of such deposits is not carried out, as at the mining enterprises the technology and working projects of selective development of man-made deposits of minerals are absent. The requirements to the technological schemes of development of technogenic deposits are substantiated and the ways of selective excavation of useful components from the tailings of concentrating factories, providing the extraction of only the most enriched sections with leaving the main mass of rocks in place of their occurrence, are proposed.

Development of self-propagating high-temperature synthesis technology with gas filtration for recycling waste metal processing of titanium and titanium alloys
- Authors:
- A. G. Makarenko
In modern engineering, where the technology of obtaining refractory compounds by powder metallurgy and the process of self-propagating high-temperature synthesis (SHS) are mastered and introduced into production, new tasks arise: reducing the cost of raw materials, creating methods of synthesizing powders and products with special desired properties, development of new technological processes. In recent years the areas and volumes of powders produced from metal chips, slags, and sludge have significantly expanded. It should be noted that the cost of powders from chips is essentially lower than the cost of powders obtained from pure metals: the cost of 1 ton of titanium powder is on average 10-30 thousand dollars, while the cost of titanium chips is 10-15 times lower. The SHS method allows to save material resources, in particular, such a strategic metal as titanium and to solve the problem of recycling of titanium-containing waste of machine-building production.

- Authors:
- B. D. Terentev
In the case of underground mining of coal seams, at present, for various reasons, a significant amount of already uncovered and prepared reserves in the form of local areas remains in the subsurface, which significantly reduces the efficiency of coal mining. Especially acute in terms of economic and environmental factors is the problem of development of local areas of powerful coal seams. In industrially developed regions of the country with high population density and developed infrastructure, where large mining and processing complexes are located, the urgent problem is the disposal of mass industrial and domestic wastes. The developed integrated technology of mining local areas of powerful coal seams with placement of solid domestic and mass industrial wastes in the mined-out space makes it possible to effectively mine the remaining reserves with simultaneous improvement of the ecological situation in the region.

- Authors:
- V. A. Alekseenko

Difference of climatic factors, complex relief, peculiarities of soil-forming and soil-bearing rocks, soils, vegetation cover determined the diversity of floodplain geochemical landscapes of the Western Caucasus. A large area of floodplains in the Western Caucasus is occupied by biogenic landscapes. Economic activities of man during the development of floodplains largely transformed the original natural landscapes. Some of them have been partially changed. For example, deforestation led to the change of its species composition. Other natural floodplain landscapes disappeared altogether, and new man-made landscapes (mainly agricultural and residential) appeared in their place. Comprehensive detailed studies of floodplain landscapes of the Western Caucasus have allowed us to assess the ecological and geochemical condition of forest ecosystems and the dynamics of its change during technogenic transformation.

Biological reclamation of land contaminated by oil products
In the biological method of land reclamation the period of restoration of anthropogenic-disturbed territory depends on the degree of soil contamination by hydrocarbons, ecological conditions of plants and microorganisms-destructors of oil-hydrocarbons. The threshold concentration of oil products in sod-podzolic soils (3 l/m 2 ) was established for meadow phytocenoses, exceeding which leads to disruption of plant life. In areas with this degree of soil contamination plant cover begins to form in the second year after the anthropogenic disturbance of the territory. The presence of oil products in the soil at a concentration of 4-5 l/m 2 causes the death of up to 95-100% of the natural flora. Based on the reaction of meadow plants we can distinguish three degrees of soil pollution by oil products: weak (1-2 l/m 2 ), medium (3 l/m 2 ) and strong (more than 4 l/m 2 ). Introduction of oil-hydrocarbon destructor microorganisms into the contaminated soil increases the germination of cultivated plants by 40-50%. It is advisable to use the biopreparation "Auros" and peat compost on the contaminated plots and sow meadow clover, white clover, common clover, awnless brome, meadow fescue, meadow tymofeevka.

Development of a methodology and structure for building a database on methods of elimination of local technogenic pollution in rock massifs
- Authors:
- O. S. Bryukhovetskii
- I. P. Ganin
The methodology and structure of the database (DB) on methods of elimination of local man-made pollution in rock massifs has been developed. At the stage of DB information model development, the relational data model with the use of the mathematical concept of the theoretical-multiple relation was applied. The choice of a way of the organization of a DB is defined as a result of the analysis of character of the placed information taking into account requirement about maintenance of direct access to it. The database is a set of normalized tables containing modules of information. Compared with databases, the construction of which is based on other principles, normalization provided more efficient operations with the database: adding, modifying and deleting data. Table normalization also allowed reducing the physical volume of the database (the size of its record on the medium) and increasing its performance.

Electromagnetic tomography and monitoring of natural and man-made matter emissions into the atmosphere
The problem of electromagnetic tomography and monitoring of cloud formations can be solved taking into account the size and parameters of the formation medium and the range of electromagnetic waves used. It is shown that for the analysis of large-scale weak formations it is necessary to use the range of ultra-long waves (wavelength of about 3 km) and conduct monitoring on the ground wave. Radio navigation systems of this range should be used, the choice of wavelength range of which is made taking into account the integral influence of formations on the phase structure of the electromagnetic field. The results of monitoring are proposed to be used as a set of expert assessments of the decision-making system.

Method for assessing and improving the reliability of mine ventilation systems
- Authors:
- O. V. Skopintseva
Assessment of reliability of mine ventilation systems of operating mines in Russia shows that its level is extremely low. Mine ventilation systems are characterized by frequent failures in the amount of air supplied to the places of consumption, which leads to the possibility of gas and dust explosions and poisoning of workers. Almost all accidents at mines resulting in the biggest losses of life are connected with failures of mine ventilation systems. For estimation of failures the integral criterion is offered, which characterizes the probability of failures, connected with reduction of air inflow into a mine due to increase of its resistance and redistribution of air in a network because of difference of actual values of its elements resistance from the design ones.

Inventory of secondary mineral resources in the system of rational subsoil use
- Authors:
- P. V. Berezovskii
At present the problems of the most complete accounting and systematic evaluation of secondary mineral resources are acute. The cadastre is a method of accounting and evaluation, which must meet modern administrative and economic conditions. Analysis of the existing cadastres of natural resources in Russia shows that they do not meet these requirements. It is necessary to make a cadastre of natural resources according to the territorial principle. Natural resources in such a cadastre must be accounted for by objects and unified classification units adopted for each type of natural resource. The cadastre of secondary mineral resources should become an integral part of the cadastre of natural resources.

International experience in using the results of scientific and technological progress to strengthen environmental security
- Authors:
- V. N. Volovich
- V. F. Erygina
- S. A. Tertyshnyi
Strengthening the environmental security of any country is directly linked to how the results of scientific and technological progress (STP) are used in the sectors of the national economy and, above all, in the extractive industries and knowledge-intensive production sectors. All this requires a significant increase in both public and private investment. In world practice, there is a positive experience of using the results of STI, which in modern conditions not only determines the level of competitiveness of the national economy, but also contributes to the strengthening of environmental security. Similar experience should be fully used by the Russian state. A comparative analysis of the economies of the fifteen largest world trading powers has shown that innovation and innovation are one of the main sources of competitive power on the world stage. Insensitivity of the Russian economy to innovation is one of the causes of technological and economic lag. In recent years the ecological factor has become important in ensuring the international competitiveness of goods. The combination of stricter environmental standards and fiercer competition on the global market makes it necessary to use the principles of pollution prevention in conjunction with environmental self-monitoring in the development of new products.

Enhancing production efficiency in the coal industry based on improving the economic mechanism of the rational use of mineral resources
- Authors:
- N. Ya. Lobanov
- E. A. Kuklina
- M. A. Nevskaya
In the conditions of market economy, the increase of efficiency of production in the mining industry is possible on the basis of perfection and development of the economic mechanism of rational use of mineral resources. One of the main objects of research in this case is the tax system, which is explained by its key importance for the effective process of development of the potential of mineral resources. The most important direction of improving the tax system in the mining industry is the transition to the rent principle of taxation, allowing to link the taxes transferred by mining enterprises to the budget, with the economic efficiency of mining production. Recommendations on improving the taxation system for enterprises of the Russian coal industry have been developed. They are used for economic assessment of the project of development and technical re-equipment of mines of the Vorkuta industrial district for the period up to 2015.
