Environmental pollution by industrial enterprises, leading to its degradation and impairing the health of the population remains an urgent concern of environmental social and economic importance. At present, more and more land is subject to man-made factors that alter the chemical composition of the soil. All this is the result of agricultural use of various pesticides, fertilizers, plant growth stimulants. But beyond that, many an important role in soil pollution are industrial emissions. This article examines the impact of the enterprise for the production of mineral fertilizers - JSC Meleuz Minetal Fertilizers - the quality of soil and environmental situation developing at a location nearby. On a functional purpose, this area is an area of growing crops. Not very safe is that this site is located within the boundaries of the sanitary protection zone. Monitoring of soil at an early stage allows you to track incipient changes in the environment. To assess the ecological status of the study area were determined indicator of chemical pollution of soils sampled at different distances from the plant, and the ranking according to the degree of ecological trouble. The results of the analysis showed that the highest concentrations of pollutants found in soil samples taken at the minimum distance from the plant. This confirms the impact on the territory of priority chemical plant emissions. Ranking in terms of chemical contamination of soils indicates that the territory adjacent to the JSC Meleuz Mineral Fertilizers, at all distances studied, should be referred to an area with critical ecological situation.

The increasing chemicalization of production and life leads to the pollution of water bodies by chemicals, the effect of which on the micro - and macro - organisms is poorly understood. This section of the study in sanitary bacteriology is becoming ever more topical and is an important task of modern hygienic science. One of complicacies of the study of the problem is related with the fact that the presence of only experimental data fails to be sufficient, as the impact of any given chemical substance on different bacteria in the experiment does not mean that under natural conditions, similar results will be obtained. One reason for this may be the inhibitory effect of the given chemical on biological properties of bacteria, while in field conditions in the water several chemicals interacting with each other can exist. In this regard, the aim of the work was to assess the indicator value of sanitary and microbiological indices of epidemic hazard of water use in conditions of chemical pollution of surface water bodies.

AbstractIn this paper, the ecological status of a section of the Danube River flowing through Serbia from Bezdan to Djerdap was evalutated. Using the chemical composition of water, sediment samples from the littoral zone and dominant aquatic macrophytes, the level of chemical pollution was ascertained. Chemical analyses of the water and sediment indicated that the tributaries flowing into the Danube significantly influenced the chemical load of the water and as a direct consequence, the sediment. The concentration of heavy metals including Cu, Mn and Cd found in plants of the Potamogeton genus, further indicated significant chemical pollution, establishing a clear link between the chemical composition of plant tissues and the chemical composition of water and sediment. This paper therefore describes how the chemical composition of aquatic plants can be used as a reliable indicator for heavy metal pollution of aquatic ecosystems.

Heavy metals are one of the major pollutants. The main sources of pollution are industry, transport, the use of pesticides and mineral fertilizers in agriculture, the military industry, etc. Pollution is mostly around businesses, highways and treated terrains and they are polymetallic, mostly from Cu, Pb, Zn, Cd, Hg, As and others. In the current paper the main heavy metals for Bulgaria for the different sources of pollution are presented. An analysis of data for problem areas is made, according to sources of pollution. An analysis of the impact of pollutants on the environment is also conducted.

It has already become a tradition to research the pollution with heavy metals of surface and groundwater. Very few studies have been done to assess the ecological status of rivers in Kosovo, based on their assessment through physical-chemical parameters, such as: pH, OT, BOD5, COD, N-NH4, NO3-, NT, PO4-P, PT. Although it is known that physical-chemical pollution of surface water is present in the flow of rivers, since in the impossibility of setting up plants for the treatment of industrial and urban wastewater, in all cases their discharge is done in a way free and uncontrolled. Therefore, our object of study consists in the real evidence of physical-chemical pollution of the waters of the Curved River (Kriva Reka), a segment of which crosses the industrial area of ​​the Artana Mine, located in the northeastern part of Kosovo. During the research work we have identified six monitoring points: M1 and M6 represent the river waters outside the industrial zone, while the other four monitoring points reflect the industrial discharge waters and the polluted river waters in the industrial zone. Classical and instrumental methods of analytical chemistry have been applied to determine physical-chemical parameters. The results obtained after the analysis of water samples give the values of physical-chemical parameters, based on which we estimate that the Curved River is characterized by poor ecological status.

The purpose of the study is to identify current trends in metallurgical technologies, taking into account environmental problems. The world is undergoing major changes in environmental policy, which has become an integral part of industrial policy and international trade. The analysis shows a certain connection between the increase in Earth's temperature and the growth of steel production in the world. Therefore, the Paris Climate Agreement, which was supported by most industrialized countries, is based on the idea of limiting and reducing greenhouse gas emissions by industrial enterprises. On the one hand, industrial emissions undoubtedly affect the ecological state of the environment. On the other hand, a sharp reduction in production emissions significantly increases financial costs. In the world, environmental requirements for metallurgical processes are gaining such a level that threatens the prospects for the development of metallurgy. It is shown that the choice of the optimal path of ecological development requires the search for new solutions to increase the level of implementation of ecological innovations by Ukrainian enterprises. To identify the impact of production technologies of different types of metallurgical products, the method of expert-mathematical evaluation using the Harrington desirability function was used. It is shown that for rolled products the rating means «satisfactory» or «good». The situation with the production of iron ore, pig iron and steel is worse - here a comprehensive assessment shows the value of «unsatisfactory» and «satisfactory». This thesis is confirmed by the fact that investments of ecological orientation of the Ukrainian metallurgical enterprises are now directed on improvement of ecological indicators in the specified directions. Prospects for the development of metallurgy in Ukraine should be associated with the implementation of new technical solutions, in particular those developments that are in the stage of exploratory research and experimental samples. Scientific developments of the Iron and Steel Institute of the National Academy of Sciences of Ukraine, aimed at reducing energy consumption and improving the environmental performance of metallurgical production

The paper analyzes the study results of the soil layer on the territory of oil and gas companies. Assessment of anthropogenic impact of oil on key chemical and biological parameters of soil is given on the basis of experimental research on the territory of the enterprise. The objects of the study was background (uncontaminated) and contaminated soil. The impact of oil pollution in natural conditions was studied by means of mapping properties of contaminated soils with their background counterparts. Soil cover is the main element of the landscape - the first assumes the environmental impact. Because of mechanical disturbance and chemical pollution there is a gradual degradation of the soil, which has become one of the major environmental problems of oil and gas complex. The research was conducted in April-May 2017. The analysis shows that the morphological characteristics of the soil have changed significantly. The analysis of the soil phytotoxicity shows a high degree of soil phytotoxicity. The percentage of humus is less than the average content in the upper soil horizon. The analysis of the chemical composition shows a relatively low level of soil contamination with heavy metals, the exception was the concentration of cadmium and cobalt. The oil content does not exceed the MPC.

The sanitary and hygienic condition of tree stands exposed to increased anthropogenic load, namely, the impact of industrial chemical pollution in the urban environment, is evaluated. The difference in the forest pathological state of trees is explained by their age, proximity to emission sources, highways, residential buildings, as well as different degrees of resistance to chemical pollutants in urban areas. The main types exposed to industrial emissions affecting the condition of tree stands are identified, with subsequent distribution by condition categories. Five reference points are proposed for studying the effects of chemical air pollution on plant biota. The characteristic species composition of woody vegetation growing on the territory of the selected objects under study was determined, and the percentage of their occurrence was calculated. At the test sites located near the sources of emissions, a high percentage of individuals affected by spot or spot necrosis and having pathological signs of the trunk, water shoots, shrunken skeletal branches and tops were noted, in contrast to the plantings located in the so-called zone of moderate pollution and at the control point at the maximum distance from the sources of emissions. Individuals promising in monitoring of atmospheric air pollution have been identified.

The paper provides new survey evidence on effects of concentrated ownership upon investment and performance in Russian industrial enterprises. Authors trace major changes in their ownership profile, assess pace of post-privatization redistribution of shareholdings and provide evidence on ownership concentration in the Russian industry. The major econometric findings are that the first largest shareholding is negatively associated with the firm’s investment and performance but surprisingly the second largest shareholding is positively associated with them. Moreover, these relationships do not depend on identity of majority shareholders. These results are consistent with the assumption that the entrenched controlling owners are engaged in extracting "control premium" but sizable shareholdings accumulated by other blockholders may put brakes on their expropriating behavior and thus be conductive for efficiency enhancing. The most interesting topic for further more detailed analysis is formation, stability and roles of coalitions of large blockholders in the corporate sector of post-socialist countries.

The article analyzes the experience of the impact of the system of forest belts and mineral fertilizers on the yield of spring wheat, including on irrigated lands. Vegetation irrigation is designed to maintain the humidity of the active soil layer from germination to maturation at the lower level of the optimum-70-75%, and in the phases of tubulation-earing - flowering - 75-80% NV. However, due to the large differences in zones and microzones of soil and climate conditions and due to the weather conditions of individual years, wheat irrigation regimes require a clear differentiation. In the Volga region in the dry autumn rainfalls give the norm of 800-1000 m3/ha, and in saline soils – 1000-1300 and 3-4 vegetation irrigation at tillering, phases of booting, earing and grain formation the norm 600-650 m3/ha. the impact of the system of forest belts, mineral fertilizers on the yield of spring wheat is closely tied to the formation of microclimate at different distances from forest edges.
