Environmental impact assessment in the Caspian region

Background. The current state and pressures associated with the anthropogenic impact on the Caspian region environment are examined. Surrounded by five coastal countries, including the Republic of Azerbaijan, the Russian Federation, the Republic of Kazakhstan, Turkmenistan, and the Islamic Republic of Iran, the Caspian Sea is the world’s largest endorheic water body. The isolation of the Caspian Sea, which is characterized by special climatic conditions and salinity gradients, has led to the formation of a unique ecosystem.Aim. Environmental impact assessment of the Caspian region and the associated anthropogenetic load.Materials and methods. The anthropogenic processes affecting the environment of the Caspian Sea and the surrounding area were assessed using the DPSIR concept. This concept includes the components of driving forces, pressures, state, impacts, and response in order to inclusively determine the connections between human activities and the environment. This concept was used as by the European Environmental Agency as the basis for integrated environmental analysis.Results. The conducted study determined the scale and geography of greenhouse gas degassing, the volume of pollutant emissions into the atmosphere by components, the structure of greenhouse gas emissions, and the dynamics of emissions of carbon dioxide, methane, and nitrogen oxide generated from stationary sources in the Caspian region. Anthropogenic emissions of greenhouse gases that pollute the atmosphere and sea waters, generated from stationary sources, are formed as a result of the production activities of a number of industries: mining; electricity, gas, and steam generation; air conditioning; manufacturing; water supply; wastewater treatment; construction industry; agriculture and forestry; transport storage and communications; repair of vehicles and motorcycles; as well as other activities.Conclusion. The share of enterprises in the fuel and energy complex that emit greenhouse gases is about 60%. The structure of greenhouse gas emissions and the dynamics of CO2, CH4, and N2O emissions generated from stationary sources in the Caspian region are shown. The Caspian Sea is one of the most important endorheic basins in the world. Being surrounded by land on all sides, the Caspian Sea lacks flows that would maintain its self-purification. Pollutants that enter the Sea remain there due to the lack of mechanisms for their removal. Complete information about the level of pollutant inputs is crucial for selecting the most effective means of environmental compensation or pollution reduction. The largest polluting sectors are agriculture, industry, including oil and gas, and urbanization.

Econometric Modeling of Environmental Pollution Factors and Their Impact on Life Expectancy in Uzbekistan

The article examines the impact of environmental pollution factors on life expectancy in Uzbekistan. The study is based on econometric modeling methods, including panel data on the country’s regions for the period of 2010-2023. The area of protected natural areas, the volume of pollutant emissions into the atmosphere, the provision of doctors and hospital beds, and access to drinking water were utilized as factors influencing life expectancy. Despite the identification of some relationships, the modeling results showed limited explanatory power of the selected models, which is associated with the low quality and incompleteness of statistical data. The study revealed significant regional differentiation and polarization in environmental indicators, which requires measures to improve the quality of data and take into account additional factors.

APPLICATION OF FLUCTUATING ASYMMETRY METHODS FOR ENVIRONMENTAL MONITORING IN KAMIANSKE

The city of Kamianske has a hazardous environmental situation due to the long and intensive development of industry, whose enterprises emit large amounts of harmful substances into the atmosphere. Therefore, the implementation of continuous environmental monitoring for the city is an urgent task that can be solved by combining instrumental measurement methods with phytoindication methods. The aim of the study is to test the methods of phytoindication in the environmental monitoring system using the indicator of fluctuating asymmetry of the leaf blade of woody plants of the Populus canadensis species and to assess the quality of the environment, taking into account the functional zones of the urban system. A methodology for assessing the quality of the environment by the integral index of the fluctuating asymmetry of the leaf blade of Populus plants has been developed and an assessment scale with different gradient values has been proposed. The integral indicator of the fluctuating asymmetry of the leaf blades of Populus canadensi plants was calculated for 30 experimental plots covering all functional zones of Kamianske. It was determined that the quality of the environment within the industrial zones is characterised as critically polluted with unfavourable conditions for living organisms, which is confirmed by the integral index of fluctuating asymmetry 0,076¸0,104. Settlement areas are characterised as polluted, with an integral index of 0,063¸0,093. In recreational areas, the state of the environment is assessed by a conditional norm of 0,054¸0,066. The results of the average integral index of leaf asymmetry of Populus canadensi plants for a ten-year period for the city of Kamianske were compared, and the lower (0,038±0,002) and upper (0,106±0,003) limits of the index were determined. The dependence of the integral indicator on the volume of pollutant emissions into the atmosphere has been established, which is confirmed by high correlation coefficients r = 0,8¸0,9 at a significance level of p < 0,05. The modelled polynomial trends predict further growth of the integral indicator of fluctuating asymmetry depending on the increase in pollutant emissions.

Влияние угольной отрасли на экономику регионов России

The article is a study dedicated to assessment of the economy of Russian regions, taking into account operation of the coal industry. Based on the hierarchical cluster analysis, 80 constituent entities of the Russian Federation were divided into groups according to the aggregated energy, environmental, social and economic indicators. The existence of a relationship between the level of the disease (according to the class of diseases – respiratory diseases, neoplasms, circulatory system disorders, congenital anomalies and malformations) and the volume of pollutant emissions into the atmosphere emitted by the coal industry companies operating in the regions was confirmed. The relationship between the social and environmental, energy and economic indicators has been determined. It is shown that the more developed is the coal industry in the regions, the higher the GRP and per capita incomes are; the higher the emissions are, the higher the incidence or burden on healthcare professionals is. At the same time, the presence of the lowest mortality rate in the leading regions of the coal industry can be associated with a high level of income of the population.

On the Asymmetry of the Nexus between Governance and Environmental Pollution

Governance has attracted the attention of researchers as a multifaceted and effective variable in the economic performance of countries during last three decades. On the other hand, with the intensification of environmental concerns of governments, the analysis of the relationship between governance and the worsening of environmental sustainability indicators, such as the volume of pollutant emissions, has also become one of the study primacies of environmental economists. The present study aimed to investigate the aforesaid relationship for a group of developing and developed countries for the period 1990 to 2020. To this end, the Nonlinear Autoregressive Distributed Lag (NARDL) model based on panel data was used, which permits examination of the existence of non-linear relationships between variables. Main results show asymmetry in the magnitude of the effects of governance indicators on carbon dioxide emissions in developed and developing countries as the coefficient of the positive shock to economic governance for developed countries (0.52) is almost twice that of developing nations (0.27). We found that economic governance enhancement has a stronger impact on reducing environmental pollution and thus protecting the environment.

Ensuring rational natural use through effective taxation

The important article substantiates the peculiarities of environmental tax administration in Ukraine and defines its importance in ensuring an ecologically oriented economy. It has been proven that from 2016 to 2020 there is an increase in emissions of pollutants into the atmosphere by more than 10.5%. A thorough analysis of the payment of the environmental tax to the relevant budget was carried out and a close relationship between the number of emissions of polluting substances and the rates of this tax was determined. It has been proven that in Ukraine the environmental tax does not ensure the performance of one of the main functions, namely the preservation of the natural environment. This situation is due to the relatively low rates of this tax, as well as the lack of an effective mechanism for controlling emissions of pollutants. One of the main directions of solving this problem is to use the experience of European countries in diversifying the tax rates under study depending on the type and volume of pollutant emissions.

ENERGY EFFICIENCY ASSESSMENT OF THE HOUSING STOCK IN BELARUSIAN REGIONS

The need to ensure energy efficiency of the Belarusian economy at the present stage is justified. Indicators characterizing the level of fuel energy consumption and the impact of fuel consumption on the environment for the Belarusian regions are calculated. The authors found that Vitebsk region is characterized by high heat capacity Gross regional product. Also, Vitebsk region is characterized by a high volume of pollutant emissions into the air. We are talking about the emissions generated from fuel combustion for the production of heat and electricity. It has been substantiated that the main directions of regional development should be to reduce the consumption of fuel resources and the volume of emissions. The authors analyzed the structure of final consumption of fuel and energy resources by sectors of consumption, which showed that the main consumers of fuel and energy resources in Belarus are industry and housing sector.In this article the highest priority has been given by authors to energy efficiency in housing sector. It is noted that improving the energy efficiency of the housing stock can reduce the energy load on the region. It is proposed to use a system of indicators to assess the level of energy efficiency. The scientific novelty is in the application of a systematic approach to assessing energy efficiency. Previous studies were limited to considering individual energy efficiency indicators, rather than their systems. It is proposed to include the following groups of indicators in the system: technical, financial and economic, environmental. In contrast to the previously proposed groups of indicators, the system developed by the authors includes environmental indicators. The relevance of their study is due to regional characteristics, which is especially important for the Vitebsk region.The proposed system of indicators is able to give a holistic view of the level of energy efficiency of the housing stock. Thus, it becomes possible to identify reserves for the growth of energy efficiency in the housing sector in Belarus.

Modeling CO2 emissions in Malaysia: an application of Maki cointegration and wavelet coherence tests.

One of humanity's most significant problems in the twenty-first century revolves around how to balance the mitigation of environmental pollution while achieving sustainable economic development. Despite increased awareness and dedication to climate change, the planet is still seeing a drastic decrease in the volume of pollutant emissions. This study explores the long-run and causal impact of economic growth, financial development, urbanization, and gross capital formation on Malaysia's CO2 emissions based on the STIRPAT framework. The current paper employs recently developed econometric techniques such as Maki co-integration, auto-regressive distribution lag (ARDL), fully modified OLS (FMOLS), dynamic ordinary least square (DOLS), and wavelet coherence and gradual shift causality tests to investigate these interconnections. The advantage of the gradual shift causality test is that it can capture the causality in the presence of a structural break(s). The findings from the Maki co-integration and ARDL bounds tests reveal evidence of cointegration among the variables. The ARDL test reveals that economic growth, gross capital formation, and urbanization exert a positive impact on CO2 emissions. Furthermore, the wavelet coherence test reveals that there is a significant dependency between CO2 emissions and economic growth, gross capital formation, and urbanization. The Toda Yamamoto and Gradual shift causality tests reveal that there is a (a) unidirectional causality from urbanization to CO2 emissions, (b) unidirectional causality from economic growth to CO2 emissions, and (c) unidirectional causality from gross capital formation to CO2 emissions.

Забруднення повітря та стан здоров'я дитячого населення України

Atmospheric air pollution is one of the main factors, which negatively affects the health of children in Ukraine. It can exacerbate chronic diseases and decrease the quality of life of children and their families. The aim to determine the correlation ranking between the incidence and prevalence of diseases among children in Ukraine in 2015 and the volume of pollutant emissions from stationary and mobile sources of pollution per person depending on the area of residence. Materials and methods. During the analysis, data from the Center for Medical Statistics of the Ministry of Health of Ukraine and the State Statistics Service of Ukraine for 2015 were used. Methods of system approach, epidemiological, correlation and cluster analysis are applied. Results. In our study we have discovered that the volume of pollutant emissions from stationary and mobile sources into the atmosphere per 1 person had a direct impact on the incidence of all diseases of children in Ukraine, especially children aged 0–6 years (p<0.01). The closest direct correlation was observed between pollutant emissions and prevalence of respiratory diseases among children, especially in children aged 0–6 years and 15–17 years and with the prevalence of bronchial asthma and diabetes in all age groups. The correlation between children morbidity level of tuberculosis, some infectious and parasitic diseases, congenital anomalies, circulatory and digestive diseases, diseases of the musculoskeletal system, ear and mammary gland and the volume of air toxic emissions haven't reached any important statistical significance. Correlation between the mortality rates of children under one year and the incidence of all diseases, including respiratory diseases, some infectious diseases, acute respiratory viral infections, pneumonia and influenza, cerebral palsy and air toxic emissions also haven't reached statistical significance. Conclusions. Morbidity and prevalence of all children's diseases was chained in different manner with the amount of pollutant air emissions. This fact indicates that the increase in morbidity is associated not only with socio-economic and medical and genetic factors, but also with environmental influence. This situation requires brings a necessity of establishment the issue of environmental safety of the population of Ukraine, especially children. No conflict of interest were declared by the authors. Key words: children, morbidity, prevalence, mortality, air pollution.

Formation of mechanisms for ensuring the sustainability of industry

The effective use of natural resources for to meet the needs of society and the state economy became relevant in the middle of the last century, when the UN began to hold the first conferences on sustainable development. Today, these issues are shifting to the prism of the efficient use of natural resources and the conservation of ecological diversity for future generations. The work analyzed the indicators on the volume of pollutant emissions, current expenditures for ensuring environmental stability and the share of disturbed lands. Because of the analysis, it was found that not all emissions and waste are effectively disposed of, and land reclamation after mining is only one third. The work presented measures to ensure environmental protection and measures that need to be implemented at the state level. In conclusion, the study presents the main findings and results of the work.

As the main task in the implementation of the Clean Air federal project, it is planned to implement comprehensive action plans to reduce emissions of pollutants into the air in large industrial centers, taking into account summary calculations of the negative environmental impacts allowed in these cities.

Urban Planning Aspects of Ecological and Urban Planning Regulation Fundamentals for Main Street and Road Network Functioning and Forward Development

The greatest influence of motor vehicles is manifested in the urbanized environment. The city is an indicator of sustainable development or an unfavourable relationship between motor vehicles and the urban environment. The study is based on an assessment of the impact of the vehicles current state on the street and road network and trunk road adjacent areas to substantiate the adopted planning protective measures and to determine the functional purpose of the trunk road adjacent areas proceeding from environmental impact on street and road networks. Anthropogenic air pollution sources are primarily represented by industrial enterprises and vehicles emissions. The main task in determining the assessment of the effectiveness of the protective solutions of trunk road adjacent areas is the correct choice of assessment criteria, according to which the efficiency of solutions will differ. Since the street and road network with all its traffic flows is an integral structural element of the city, its impact on the environmental performance of the urban environment can undoubtedly be called the prevailing one. It is necessary to highlight noise, airborne emissions and air (atmosphere) pollution among the main environmental impacts, the source of which is the functioning of the street and road network. Since the street and road system is the main tool in wastewater collection and disposal, it also has a direct impact on the ecological condition of hydrosphere objects, i.e. groundwater, springs, water bodies. Its environmental impacts on the urban setting's lithosphere are also evident: road surface contamination, lubricant residues and gasoline pollute the soil during the removal of rain and melt wastewater. It is impossible to rule out the harmful effects of electromagnetic loads from rail vehicle operation. According to the State Statistics Service of Ukraine, the quality of atmospheric air in a modern developed city is primarily dependent on the volume of pollutant emissions, the two main sources of pollution being stationary 15…30% and mobile 70…85% (using Kyiv's example).

Analysis of Technogenic Loading on the Air Basins of Individual Industrial and Municipal Aglomerations of Eastern Ukraine (Using Dnipro City as an Example)

Purpose. Estimation of atmospheric air pollution level in the Dnipro city in modern conditions and technogenic loading on the air basin of the Dnipropetrovsk region. Methods. Statistical. Results. Volumes of pollutant emissions from stationary sources are 4 times more than emissions from mobile sources. The maximum values of emissions of pollutants are noted for the enterprises of the processing and extractive industry. The estimation of the level of air pollution in Dnipro city was carried out. An increase in the level of contamination in Dnipro city was indicated during the study period. Substances for which the quality of atmospheric air constantly does not meet the standards include dust, nitrogen dioxide and formaldehyde. The level of atmospheric air pollution can be classified as «polluted» and «highly polluted». The module of technogenic loading on the air basin of the Dnipropetrovsk region and Dnipro city was calculated. The rate of the technogenic loading in Dnipropetrovsk region from stationary sources considerably exceeds the mobile ones. In Dnipro city, the level of technogenic loading from stationary sources is an order of magnitude higher than the corresponding in the region. This indicates a significant level of technogenic loading on the Dnipro city air basin exactly from stationary sources. The volume of pollutant emissions from stationary sources in the region is an order of magnitude higher compared to the same in Dnipro city and the area of the region is two orders of magnitude larger. The reduction of the level of technogenic loading on the air basin of Dnipropetrovsk region as a whole was noted. Conclusion. Dnipropetrovsk region belongs to regions with significant industrial potential. The primary tasks for the improvement of the air basin are the development of measures to reduce emissions from stationary sources, as well as optimization of the monitoring system in order to determine the list of priority pollutants.

Benzo[a]pyrene contamination in Rostov Region of Russian Federation: A 10-year retrospective of soil monitoring under the effect of long-term technogenic pollution

The aim of the current work was to study the main tendencies in the accumulation and distribution of benzo[a]pyrene in soils of the affected zone of the Novocherkassk regional power plant. Studies were conducted on the soils of monitoring plots subjected to Novocherkassk regional power plant emissions. Monitoring plots were established at different distances from the Novocherkassk regional power plant (1.0–20.0 km). Regularities in the accumulation and distribution of benzo[a]pyrene in chernozemic, meadow-chernozemic, and alluvial soils under the effect of aerotechnogenic emissions from the Novocherkassk regional power plant have been revealed on the basis of long-term monitoring studies (from 2002 to 2011). The tendencies in the distribution and accumulation of BaP in the studied soils coincided during the 10 years of monitoring studies. It has been found the 5-km zone to the northwest from the power station, which coincides with the predominant wind direction, is most subjected to contamination by benzo[a]pyrene, with the maximum accumulation at a distance of about 1.6 km from the source. Dynamics of pollutant accumulation in soils depends on number of Novocherkassk regional power plant emissions. The content of benzo[a]pyrene in the soil is an indicator of the technogenic load impact on the areas, for which the combustion products of hydrocarbon fuel are the major pollutants. A gradual decrease of the pollutant content in the soils was revealed during the period from 2002 to 2011. It explained by the significant decrease in the volume of pollutant emissions from the plant and the self-purification capacity of soils and mechanisms of benzo[a]pyrene degradation.

Morphological parameters leaves woody plants in an urban environment (on Gomel example)

At present much attention is paid to the investigation of the indicative features of organisms on the whole and vegetative objects in particular. However, it should be noted that sources of toxic elements distributed unevenly on the territories and having various character and intensity in the form of the enterprises and constructions create rather motley picture of environmental pollution both by structure of pollutants, and by their concentration. Therefore an important scientific problem is the examination not only of changes in conditions of technogenic influence in general, but the research of dependence of intensity of morphological plants parameters change on structure and concentration of chemical pollutants in the environment, and also the assessment of possible consequences of pollutants accumulation in vegetative objects. This was the aim of this work. To perform the work used landscape-geochemical analysis include, extending the definition of the emission factor load, characteristic technogene sources of pollution in the form of industrial plants, evaluation of storage medium (vegetation). Vegetation condition was assessed by determining morphological parameters - the length and width of the leaf blade. The article presents a comparative assessment of the anthropogenic impact level of the largest industrial enterprises on the air state in the city of Gomel. Enterprises of western and southern industrial zone have proved to make the greatest contribution to the urban air pollution. The value of the standard deviation was used to assess the degree of anthropogenic impact of industrial enterprises on morphological parameters of woody plants. This index increased in the western and southern industrial zones in the direction from the enterprises with the large volume of pollutant emissions to the enterprises with the small volume of emissions. This trend is caused by stabilizing selection action due to the environmental stress in the form of emissions of the industrial enterprises in these zones. It is also revealed that in western and southern industrial zones the formation of the leaf blade length and width depends more on the level of anthropogenic impact of the chemical plant, combined heat and power plant, JSC «Centrolit» and JSC «Gomeldrev» compared with other companies, that should be considered when further improvement of environmental activities. The results are generally characterized by scientific novelty of the research and can be used for the purpose of indexing the level of anthropogenic impact on urban areas and further improve the methods of monitoring the state of the urban environment. Next it is planned to evaluate the morphological parameters of the leaf blade of woody plants growing in the area of two large industrial enterprises of the Gomel region – JSC «Mozyr Oil Refinery» (Mozyr), JSC «Belarusian Metallurgical Plant» (Zhlobin) and in city parklands. Then the further testing of the heavy metals content will be carried out in the samples of woody plants, grasses and soil from the territory of the industrial enterprises and parklands of the city of Gomel, Mozyr, and Zhlobin.
