Crucial for the research on adaptiogenesis of introduced coniferous species is the study the anatomical structure of their vegetative organs, especially the needles, which provides the productivity of individual trees and plantings in general. In conditions of anthropogenic pressure of the environment there are changes in the thickness and structure of the histological elements of vegetative organs of coniferous species, in the first place, protective tissues. Therefore, the study of the anatomical structure of the needles is relevant in the context of studying the ways and mechanisms of adaptation of gymnosperms to industrial emissions and the finding sensitive phytoindicators of environmental pollution and the condition of coniferous plants in man-made zones. However, today the chronic effect of phytotoxicants on the anatomical structure of needles is insufficiently studied. Ecological and anatomical studies of P. pungens in the conditions of the steppe zone of Ukraine for the effects of technogenesis are practically absent. Prydniprovsk TPP is the largest source of pollution in the city of Dnipro (Ukraine): its emissions make up 68,9 % of the volume of toxic compounds of all enterprises and transport facilities. The main pollutants of emissions from Prydniprovsk TPP are SO2, NO2, solids, CO. In order to reduce the negative impact of the TPP emissions, green plantations mainly from softwood are created around it, which purify the atmosphere and improve the environment throughout the year. In view of this, the purpose of the work is to analyse the state of morphological and anatomical indices of the Picea pungens Engelm f. glauca Beissn. needles under the influence of emissions from Prydniprovsk TPP. The research is conducted according to generally accepted methods (Zlobin et al., 2009; Albrechtova, 2003; Permjakov, 1988). It has been found that the length and weight of needles in experimental specimens of P. pungens decrease with respect to the values of these indices in plants of relatively pure zone; therefore, they are sensitive growth parameters to the action of environmental pollution. Nevertheless, the intensity of the growth of P. pungens needles does not change; therefore, it is not an informative feature for assessing the living conditions of the prickly fir in the industrial zone. The analysis of the micromorphological features of P. pungens needles showed resistance to anthropogenic pressure of its characteristics, such as width and thickness, although the area of needles decreases, which is associated with a significant decrease in the technogenic conditions of the environment of its length. In plants of P. pungens, growing on the territory adjacent to Prydniprovsk TPP, the size of the constituents of needles of P. pungens (epidermis and hypoderms), as well as the number, diameter and type of placement of resin passages in the mesophyll of the needles do not differ significantly from such indices in plants of relatively pure zone indicating the stability of these features and the resistance of the needles of the investigated species to the emissions of TPP. The thickness of the assimilation parenchyma from the adaxial side of the needle of P. pungens in the conditions of technogenesis increases. Among the histological elements of the needles P. pungens the greatest influence of man-made emissions is experienced by the components of the central conductive cylinder: the layer of endoderm thickens by 15,9 %, as compared with the control value, which we consider as an adaptive reaction of plants to man-made stress; the diameter of the central conductive cylinder and the thickness of xylem increases. Probably this is due to the need for better water supply of plants. Thus, in the conditions of technogenesis, stability of the histological characteristics and plasticity of the morphometric characteristics of the needles P. pungens were revealed. The formation of adaptive mechanisms of compensatory type in the needles of P. pungens under the influence of phytotoxicants was found: there is an increase of the size of the endoderm, mesophyll, xylem and the central conductive cylinder of the needles. It is shown that the ratio of particles of histological structures of needles (in %) to the action of pollutants of TPP remains practically unchanged. The informative test parameters for monitoring studies of the condition of coniferous plants in man-made zones (mass, length and area of needles) are suggested. Estimation of P. pungens resistance to the components of the thermal power plant's emissions as a medium-resistant species. It is recommended to use P. pungens in landscaping of contaminated areas.

The study presents analysis of current air pollution state over Ukraine including remote regions and uncontrolled Ukrainian territories; features of NO2, SO2, and CO spatial distribution and seasonality under the influence of local anthropogenic emissions. The research is based on Sentinel-5P satellite data for the period of November 2018 – January 2020. Despite the increasing traffic emissions, the industrial emissions still greatly influence the air pollution in Ukraine. Sentinel-5P coverage allowed detecting a number of cities with huge anthropogenic NO2 and SO2 emissions, where ground-based measurements are absent. Uncontrolled territories on the east part of Ukraine still negatively affect air quality in the region due to the activity of coal-fired thermal power plants. The study indicates significant air quality changes during the heating season in winter and open burning in March – April. There were found differences in NO2 seasonal variability over clean remote regions and industrial zones. The paper analyzes features of shipping emissions during the tourist season for Ukrainian coastline of Black and Azov Seas, showing huge negative impact of chaotic movements of tourists boats near the Dzharylhach National Nature Park.

Material processing by PT Tukad Mas Kota Bima which has a negative impact, namely the existence of pollution or environmental damage in the East Rasa Nae Subdistrict, Bima City, so that it can be held accountable under criminal law, civil law and administrative law. The purpose of this study was to determine the form of criminal liability for environmental damage due to material processing by PT Tukad Mas Kota Bima. The research method used is empirical legal research with data collection techniques through interviews and documentation. The findings of this study indicate that legal liability for environmental damage due to material processing by PT Tukad Mas Kota Bima can be seen in aspects of criminal law, civil law and administrative aspects. However, the Bima City Government through the Environmental Service has only given a written warning to PT Tukad Mas Kota Bima, which has been operating for decades. Whereas empirical facts have shown that there is quite severe damage, such as waste disposal that can have a health impact on the community and natural damage due to excavations carried out. Criminal liability should be a special concern, NGOs and the community even report on environmental crimes, the report is because the result of material processing causes environmental pollution as one of the elements of criminal acts against environmental pollution.

Cooling reservoirs of thermal power plants represent the special class of natural/ engineering systems with, on the one hand, natural geo/systems as one subsystem and, on the other hand, production/technological units as the other subsystem. Studying of these ecosystems’ functioning regularities seems to be helpful for water quality management and rational organization of water use. Besides, it is topical due to the low level of the relevant knowledge in the North of the Western Siberia. The authors for the first time in the Middle Ob Region have carried out a two-year session of monitoring of hydro/chemical indicators and temperature regime of the thermal power plants cooling reservoirs in the riparian stripe of water area. All previous investigations were done only by industrial water users within the frameworks of production monitoring in terms of three indicators in three points of the cooling reservoir water area downstream the power plant dam. Spatial distribution of concentrations of biogenic ions, salt composition, pH, organic matter, and metals in specific natural/technological system of the Surgut hthermal power plants’ reservoirs has been analyzed for the first time for the conditions of the Western Siberian taiga zone. Sources of anthropogenic pressure upon a water body have been identified. According the results of the indicators’ spatial distribution analysis three sections of the Surgut reservoir water area have been separated: a background section of the Chernaya River; a section upstream the dam with predominantly recreational character of the anthropogenic pressure; and a sectio0n downstream the dam with anthropogenic pressure of technological origin. According the outcomes of the correlation analysis indicators of the anthropogenic pressure character have been reveald.

Energy is the basic sector of the economy and the largest consumer of primary energy resources of any country, which is why the development of world energy is accompanied by global pressure on the environment. The issues are considered of reducing the atmospheric impact of emissions of thermal power plants, improving the reliability and working life of their units, systems, and plants as a whole. The principles are presented of development and improvement of technologies for processing industrial emissions of thermal power plants, the neutralization of which is currently relevant on a regional and global scale. Analysis is carried out of existing methods of cyclone and filtration treatment. An improved design of a cyclone filter is proposed, which allows to increase the reliability of gas turbine and steam-gas units of TPP, while ensuring the efficiency of separation of the suspended part of the flow at the gas treatment point (GTP) of TPP. Similar devices can also be used to increase the degree of cleaning atmospheric emissions released by the TPP coal dust preparation and flue gas systems at coal generation from fi ne particles of PM10 and PM2,5 classes (coal dust and ash), owing to reduction of the size of caught particles from average values for cyclones and wet scrubbers of the order of 5–10 μm to 0.5 μm. The design of the cyclone filter is improved as a result of research of cyclone filtration by methods of Computational Fluid Dynamics (CFD). A system of Reynolds-averaged equations of a single-phase Navier-Stokes flow is used for mathematical modeling of motion in the cyclone filter. To determine the efficiency of separation of the suspended part of the flow in the cyclone filter, the Rercomplex is used obtained by reducing a set comprising the Navier-Stokes equations and the equation of particle motion based on Newton's law to a dimensionless form. Numerical characteristics of the suspension sedimentation from a multiphase flow in a cyclone separator of specified dimensions are found by means of the Rercomplex. The results of bench tests of the proposed design of the cyclone filter are given.

Juice «vitgrass» made from green wheat sprouts is a valuable biologically active product that has a stimulating effect on the physiological state of a person. Hydroponically grown raw materials for juice production contain proteins, fats, carbohydrates, a large group of vitamins, macro- and microelements, antioxidants, enzymes and other substances. As a part of health programs, the use of this juice is recommended for overweight people to optimize the metabolic processes of the macroorganism. A healthy lifestyle involves reducing the negative impact of environmental factors, including diet correction, on the microbiota of the gastrointestinal tract. The cumulative biological assessment of wheatgrass juice should take into account the results of its effect on the indigenous microflora. Lacto- and bifidobacteria, including industrial strains for the manufacture of probiotic preparations, represent an adequate model for studying the bacteriotropic effect of any plant-based product. The experimental results indicate a pronounced stimulating effect of juice from green wheat sprouts on the growth parameters of probiotic bacterial cultures. Strains of lacto- and bifidobacteria when cultivated under conditions of maximum limitation of nutrients in the composition of the "poor" nutrient medium with the addition of "Vitgrass" juice reacted with an increase in the level of accumulation of cell biomass and a higher activity of acid formation in comparison with the control. The analysis of the results obtained makes it possible to estimate the magnitude of the effects of stimulation in relation to both bacterial cultures as quite comparable, taking into account the known intersstrain differences in growth parameters and their biochemical aspects. This is confirmed by an almost similar increased level of carbohydrate utilization in both variants of culture liquids in the presence of juice. The potential of the positive bacteriotropic activity of "Vitgrass" juice in relation to the representatives of the indigenous microflora can be realized in different ways. It seems expedient to use the product from green wheat sprouts more widely as part of programs for the complex health improvement of the macroorganism, including the prevention and correction of dysbiotic conditions.

To date, there is research carried out on the effects of electromagnetic radiation on living organisms, studies are conducted on substratums that were subjected to microwave radiation. This radiation comes from a common household appliance; however, the effect of this type of radiation on the vitality of organisms is poorly researched. The purpose of the current analysis is to identify the morphological changes in vegetative organs of the test objects using microwave-irradiated water as a substrate. The object of the study – the onion plant (Allium сера L.), which is perfect for objectifying environmental risks. The results showed that using the water warmed up in a microwave increased the level of oppression in the morphometric parameters. In particular, there was a clear trend of reduction of growth parameters of vegetative organs and decrease in their mass (in the test group compared to the the main one the length of the root and shoot of a plant are less than 20.5% and 27.5%, and the weight is 32.3% and 63.8% less, respectively). The correlation analysis showed that the root length is the most reliable morphometric indicator that reacts sensitively to changes in water quality caused by microwave irradiation (r = –0.9995).

One of the effective ways to solve the environmental problems of the region at present is the waste disposal from Novocherkasskaya TPP, one of the largest sources of environmental pollution. The solution to this problem is associated with the integrated use of ash and slag mixtures components in the effective building materials’ production. On the TPP waste basis, the authors obtained structural and heat-insulating concrete with enhanced physical, mechanical and operational characteristics.

National and global health policies are increasingly recognizing the key role of the environment in human health development, which is related to its economic and social determinants, such as income level, technical progress, education, quality of jobs, inequality, education or lifestyle. Research has shown that the increase of GDP (Gross Domestic Product) per capita can provide additional funds for health but also for environmental protection. However, often, economic growth is associated with the accelerated degradation of the environment, and this in turn will result in an exponential increase in harmful emissions and will implicitly determine the increasing occurrence of non-communicable diseases (NCDs), mainly cardiovascular diseases, cancers and respiratory diseases. In this paper, we investigate the role and effects of economic growth, environmental pollution and non-communicable diseases on health expenditures, for the case of EU (European Union) countries during 2000–2014. In order to investigate the long-term and the short-term relationship between them, we have employed the Panel Autoregressive Distributed Lag (ARDL) method. Using the Pedroni-Johansen cointegration methods, we found that the variables are cointegrated. The findings of this study show that economic growth is one of the most important factors influencing the health expenditures both in the long- and short-run in all the 28 EU countries. With regards to the influence of CO2 emissions on health expenditure, we have found a negative impact in the short-run and a positive impact on the long-run. We have also introduced an interaction between NCDs and environmental expenditure as independent variable, a product variable. Finally, we have found that in all the three estimated models, the variation in environmental expenditure produces changes in NCDs’ effect on health expenditure.
