In recent years, according to experts, the emissions change clearly shows that urban air pollution has increased as a whole, as opposed to an overall emissions reduction in countries. In hundreds of cities of the world average air pollution levels exceed the sanitary standards. So in Almaty city thermal power plants are the largest stationary sources that contribute to air pollution. The article deals with laws of modern spatial and temporal distribution of carbon monoxide in the air basin of Almaty city, depending on the distance from TPP – 2 (thermal power plants). In particular, research shows that there is a direct relationship between the level of air pollution and wind conditions of the city.

Abstract Vietnam’s urban areas have faced serious environmental pollution issues, including water pollution, municipal waste, and air pollution. Vietnam’s real gross domestic product (GDP) has been experiencing positive growth for the past five years since 2016. And in 2019, Vietnam’s real GDP increased by 7.02% compared to the previous year. To maintain the growth rate, there is a huge amount of electricity required, not accounting for the other sectors. Thermal power plants generate more than 50% of total electricity in Vietnam, therefore, it is said that coal-fired power plants have been the major sources of air emissions and caused a serious impact on the environment. Recently air pollution is a hot issue in Ho Chi Minh City (HCMC), the air quality is being polluted by PM2.5, O3, CO, NO2, and TSP. Despite that, the neighboring areas of the city will install more coal-fired power plants, threatening to degrade the quality of the environment. Therefore, the objectives of this study are (i) Modeling the impacts of thermal power plants in SouthEast and SouthWest areas on the air quality of HCMC for two scenarios (current status in 2019 and future according to Power planning VII (adjusted) toward 2030); And (ii) Develop interprovincial air quality protection solutions. The research applied the TAPM model for meteorological modeling and AERMOD model for air pollution dispersion. The annual average PM2.5 concentration in the study area was approximately 0.121 μg/m3 and the highest concentration at a location close to Vinh Tan thermal power center with 8.61 μg/m3. NO2 the annual average concentration from power plants in 2020 and 2030 blows to HCMC and contributes to HCMC’ air quality only 0.01 and 0.03 μg/m3, respectively. The 24 hours average concentration of SO2 from power plants in 2030 blows to HCMC and contributes to HCMC’ air quality of 10 μg/m3. The 24 hours average SO2 levels of HCMC in 2030 is 39.2 μg/m3, higher than WHO’s guideline (20 μg/m3). Currently, air pollution in HCMC is polluted by PM2.5, SO2, and NO2 and cause bad effect to public health. However, in the future with the contribution of 33 thermal power plants under intercity/provinces air pollution dispersion, air pollution HCMC will be worse and affect public health. Air pollution HCMC will be a huge impact on HCMC’s public health in the future due to the contribution of 33 thermal power plants under intercity/provinces air pollution dispersion. The paper developed 7 main mitigation measures to reduce the impacts of air pollution from the power plan and reduce the impacts of air pollution on HCM’s public health. The measures are focused on using clean fuel, advanced technology, and controlling trans-provincial air pollution.

The number of thermal power plants is growing due to the industry development and the growth of energy consumption. This leads to an increase in harmful emissions in the atmosphere. There is a necessity to control the emission concentration level in the areas of power plants location. The aim of this work was to study the level of pollution concentration at different distances from the source. The mathematical model and the numerical algorithm were verified by solving test problems and comparing them with the experimental data and numerical results of other authors. Furthermore, the pollution distribution in three-dimensional case was investigated in a real physical scale. CO2 was considered as polluting gas. As a real example, the Ekibastuz SDPP-1 coal-fired thermal power plant was simulated. The remarkable feature of this thermal power plant is that the pollution emits from two chimneys of different heights (330 and 300 m). The results showed that due to the difference between chimney heights (30 m), the pollution concentration from the higher chimney dropped far away from source, than from the lower one (2160 and 1970 m, respectively). Obviously, building higher chimneys helps to reduce the harmful impact of emissions on the environment. Also, it can be used to control the emissions level at already existing power plants.

Abstract One of the 17 types of severely polluting sectors in the nation is thermal power plants which exert pressure upon the environment and health aspects in several ways e.g. creating thermal, air, and water pollution, exacerbating physiological acute and chronic responses, and affecting the subjective wellbeing of an individual residing proximal to the source. Situated on the right bank of the Rupnarayan river, Kolaghat thermal power plant is one of the major power generating plants of West Bengal, which is also producing 7500-8000 metric tons of fly ash every day but having only 325 acres of land for its disposal. Hence the plant has been exerting pressure upon the surrounding environment since its establishment and growth between 1980-1985. This study is to evaluate the overall impact of thermal power plants on the local environment and public health using a composite index that incorporates environmental and health dimensions i.e. Air quality index, drinking water quality index, land surface temperature, social parameters, Non–communicable disease rate, etc. The study reveals the local-level impact of air pollution and the impact of fly ash emissions. Nandakumar, Tamluk, and Kolaghat have been identified as blocks under stress. The workers of the plant have reported undesirable thermal and ambient air quality conditions within the battery limit, with the prevalence of skin problems, allergies, and fatigue among them. Site-specific plantation and phytoremediation techniques with the use of riparian buffers have been recommended.

An analysis of TPP wastewater, as well as technologies and equipment for their treatment, for choosing a rational mode and determining the maximum permissible concentrations of harmful substances characteristic of the energy industry before discharge into reservoirs was carried out. The compositions of the listed effluents are different and are determined by the type of thermal power plants (TPP) and the main equipment, its capacity, type of fuel, composition of the source water, method of water treatment, etc. For example, water after cooling turbine condensers and air coolers usually carries so-called thermal pollution, since its temperature is 8...10 ºС higher than the temperature of water in the water source. In some cases, cooling water can introduce foreign substances into natural reservoirs. In order to reduce the level of soil and groundwater pollution, local wastewater treatment facilities were constructed at thermal power stations. The second method is the collection of waste water in specially created containers with subsequent purification using sedimentation tanks and filters, which have anthracite or activated carbon as a filter material.
TPP waste water is diverse and the chemical composition of each of the effluents is different. Wastewater treatment technology is complex and multi-stage and requires a large amount of various equipment.
The ITTF of the National Academy of Sciences has developed a multi-purpose rotor-type aeration and oxidation plant (AORT), which works according to the method of discrete-pulse energy input (DPEI). This installation makes it possible to speed up the rate of heat and mass exchange of chemical reactions in water and water systems by 25-30 %. It makes it possible to reduce the duration of cleaning processes, reduce energy consumption by 2-3 times and consumption of reagents by 20-25 %. The AORT installation is used to clean sewage from iron, manganese, hydrogen sulfide, carbon dioxide, sulfates, and nitrates.

In India, the problem of air pollutions increases due to boosting in size of population, industrialization, and urbanization in the last few decades. Thermal power plants and transport sector is the biggest contributor to air pollution in the country. In 1980, National Crop Loss Assessment Programme (NCLAN) was established for assessing current economic losses in agriculture by air pollution. Air pollutants are present in the forms of gases, p articles in suspension, different ionizing radiation in atmosphere and they cause directly or indirectly effects on agriculture crops as well as effects on animals and humans also. Reductions in leaf area,biomass, chlorophyll, ascorbic acid, and N contents have often been observed for the crop species growing in a polluted area. Black carbon directly absorbs sunlight, reduces the amount of light for photosynthesis and caused more damage to the crops and reduce the yields of the crops.

In this paper the trace elements composition data for coal samples from the Borodino and Balakhtinskoe coal deposits of the Krasnoyarsk Territory was giving by results of laboratory chimichal studies. During coal combustion in typical domestic oven 45 trace elements and their emission factors were taken. The obtained results are correlated with the emission characteristics of the Krasnoyarsk Power Plant. It is shown that the variability of the spectrum formed during the combustion of coal, pollutants, trace elements and their compounds is wide and should be taken into account in the regulation, control and supervision of industrial emissions from thermal power plants.

The air basin of cities is subjected to considerable pollution, including waste gases generated during the production of thermal and electric energy by power plants. However, power plants are an indispensable element of the life support system on urban areas and they can not be taken out of the city, that means minimizing losses, both material and energy. Therefore, the problem of the correct choice of structural elements and operating characteristics of the process and a system for reducing air pollution is becoming very important. The paper analyzes the most well-known and practical scientific approaches to the selection of optimal measures to reduce air pollution, their advantages and disadvantages are revealed. The authors have singled out the physical and energetic approach as the most acceptable one. The approach is based on the theory of dispersed systems stability, the analysis of the main provisions which allowed us to systematize the parameters of properties, energy parameters and stability of gaseous pollutants formed during the operation of power plants and to construct a scheme for the transformation of gaseous pollutants for the process of reducing air pollution has been performed. At the same time, stability is the resultant criterion characterizing the gaseous pollutants behavior.

The goal of this research study is to compare the air quality of two urban locations from Targu-Jiu County namely Rovinari and Turceni. Measurements of SO2 content with automatic analysers were used as a criterion to asssess the air quality. Rovinari and Turceni areas were chosen for this study due to the fact that there are located two thermal power plants considered high stationary sources with an important contribution to regional and global pollution by sulfur dioxide, nitrogen oxides and dust. Sustainable development of fossil fuel power plants cannot be done without the use of technology to limit or eliminate environmental pollution. Studies regarding determination of SO2 content in the monitored areas were performed from January to December 2014. By interpreting the results obtained it can be concluded that the concentrations of sulfur dioxide in the ambient air are below the limit value set in legislation. This is mainly due to the developing of the programs for the progressive reduction of annual emissions of sulfur dioxide, nitrogen oxides and dust which was set up by operators of thermal power plants in order to comply with emission limit values. The high level of SO2 concentration in cold season is attributed to intensifying the burning of fossil fuels for household activities.

The energy saving issues are becoming necessary worldwide, as excessive consumption of energy leads to the consumption of a larger amount of fuel, increases environmental pollution and negatively affects the ozone layer. In Iraq, in particular, the demand for central air conditioning systems and home air conditioners with high electrical capacity has become increasingly clear in the recent years. Air conditioning systems within residential and public buildings, as well as government facilities became a necessity for good internal comfort, which was driven by desertification, high temperature, air pollution and increased population, resulting in increased consumption of electric power and pressing of power plants. Aiming at usage of renewable energy sources, the proposed system uses solar collectors as auxiliary solar thermal compressors and integrate them with air conditioning systems. The proposed solution will increase the cooling system efficiency, reduce electricity consumption and pollution.

Growing pressure on businesses to disclose environmental information also implies an increase in the volume of such disclosures. This article is an attempt to present the guidelines and to assess the levels of environmental information disclosure in Bulgaria.Companies, which were identified as the most responsible for air pollution, are thermal power plants. We have studied only these, which produce electricity. A checklist, containing 17 environmental performance assessment criteria, was developed and was completed based on the information, disclosed in the companies' annual financial statements, their activity reports and their websites. Based on a comparative analysis of the quantitative and qualitative information, disclosed by examined companies, we discovered that most companies disclose quantity environmental information, largely neglecting qualitive information. Taking into account the character of their activity, they should disclose more environmental information, especially qualitive information.

Abstract Air pollution is a worldwide and a local issue caused by energy generation. It refers to global warming deterioration in human environmental health and local-global sustainability. This review provides information on the generation and consumption of energy with their air pollution mixture of many pollutants; gases, liquids and particles. These pollutants have become one of the leading environmental hazards to human and planet health. The components of pollutants that result from burning fossil fuels (oil and gas) and coal have been studied, such as sulfur dioxide, carbon dioxide, nitrogen oxides and particles. Both sulfur dioxide and nitrogen oxides interact with water to produce acid rain. Both gas and oil-fired thermal power plants emission today and in the future might be transformed to work on renewable energy sources. The results stated that gas-fired power plants are more generally faster efficient, less pollution than oil and coal power plants. A complete assessment of exhaust gas treatment was conducted. Carbon dioxide capture, desulfurization, denitrification, and particle collection were all successful as treatment control mechanisms. So, previous studies presented some methods for reducing nitrogen oxides and sulfur oxides through water injection and exhaust gas recycling. The addition of nano-additives in diesel emulsion fuel (W/D) has recently been shown to increase the characteristics and performance of the fuel while reducing the quantity of emitted hydrogen chloride (HC) and carbon monoxide (CO). It was determined that the best nano-additives for W/D were Aluminum Oxide (Al2O3), copper(ii) oxide, magnesium oxide (MgO), manganese oxide (MnO), and zinc oxide (ZnO), among others (E10).

The main sources of anthropogenic emissions into the atmosphere of Murmansk are emissions from thermal power plants and boiler houses operating on fuel oil. As a result of the analysis of the dynamics of pollutant emissions from stationary anthropogenic sources for the period 1997-2019 it has been established that the level of air pollution is assessed as low; there is a tendency towards a decrease in gross emissions from stationary sources. The main pollutants from thermal power plants are sulfur dioxide, nitrogen oxides, carbon monoxide, formaldehyde, and benzo(a)pyrene. Together with gaseous and liquid substances, fuel oil ash and products of incomplete underburning of fuel, which include heavy metals V, Ni, Cr, Pb, Fe, Sn, enter the atmospheric air. Technogenic compounds of heavy metals and other pollutants from the enterprises of the power unit, falling out with dust or precipitation on the surface and catchment areas of lakes, affect the formation of the chemical composition of surface soils, waters and bottom sediments of water bodies. This is reflected in an increase in the concentration of heavy metals (in particular, V and Ni) in the water and bottom sediments of the lakes of Murmansk in comparison with the background values.

The process of coal combustion results in coal ash, 80% of which is very fine in nature & is thus known as fly ash. Presently, in India, about 120 coal based thermal power plants are producing about 90-120 million tons of fly ash every year. With increase in demand of power energy, more and more thermal power plants are expected to commission in near future and it is expected that fly ash generation will be 225 million tons by 2017. Disposal of fly ash requires large quantity of land, water and energy and its fine particles, if not disposed properly, by virtue of their weightless, can become air born and adversely affect the entire Environment. These earth elements primarily consist of silica, alumina & iron etc. and its physicochemical parameters are closely resembles with volcanic ash, natural soil etc. These properties, therefore, makes it suitable for use in ceramic industries and helps in saving the environment and resources.

Thermal power generation based on coal-fired power plants has the advantages of stability and controllability and has been the largest source of electricity supply in China. Coal-fired power plants, however, are also accompanied by high carbon emissions and the release of harmful substances (mainly including sulfur dioxide, nitrogen oxides, and smoke dust), and are even regarded as the “chief criminal” in terms of air pollution. However, thermal power is also a pioneering industry involved in several environmental regulations and cleaner production techniques before other industries. Evidence of this is China’s ultra-low emissions (ULE) policy on coal-fired power plants, implemented in 2015. To verify this policy’s effect, this study treats ULE as an exogenous impact variable, examining its emissions reduction effect on SO2, NOx, and smoke dust in Eastern and Central China using the difference-in-difference method (DID). The results show that the total emissions of the three pollutants were abated by 0.133%, 0.057% and 0.036% in Eastern, and by 0.120%, 0.035% and 0.043% in Central China at every 1% rise of thermal power generated after ULE. In addition, several other factors can also argue for the promotion of thermal power. Other industries, such as steel or chemical, have proven that they can contribute significant SO2 and NOx emissions. Based on these results, we provide suggestions on synergistic emissions reduction among multiple industries, as well as a discussion on the necessity of implementing ULE in Western China.

The purpose of this paper is the experimental analysis of the thermoelectric power plant Grozavesti impact on Bucharest urban agglomeration for year 2015. Experimental research is done for the NOx and SO2 pollutant for all seasons. The thermoelectric power plant Grozavesti is located near the Botanical Garden. Data provided by the industrial source are processed and constitute the input for the determination of the NOx and SO2 concentrations by using the OML (Operational Local Model) air quality dispersion Gaussian model. The results from modelling shows that the highest NOx and SO2 concentrations occur in the winter and autumn periods, due to unfavorable meteorological dispersion conditions and due to the operation of thermal power plant Grozavesti in the cold seasons. Thermoelectric power plants Grozavesti, operate on natural gas, because power plant have been refurbished. Generally, the results show that the industrial power plant represent the main contributions for pollution when the NOx and SO2 are exceed the limit value, according to Law 104/2011- ambient air quality, and this affect vegetation and human health.

Topicality. The problem of anthropogenic impact reducing on atmospheric air is especially relevant to date. Ukraine ranks one of the first places in the world of mortality rate from environmental pollution and one of the main sources of pollution is the operation of coal installations.Most of the equipment of the large power plants of Ukraine is in the pre-critical state, it is morally and physically obsolete. Unsatisfactory condition of environmental technologies and non-compliance with international requirements of the cleaning of atmospheric air emissions from the thermal power plants are the urgent issues of the current international economic and environmental policy of the country. Aim and tasks are to determine the prospects of introducing and improving the environmental management system at Large Combustion Plants in Ukraine in the context of the National Plan for Reducing Emissions to reduce the environmental risks posed by pollutant emissions from heat power plants and the entry of Ukraine into the international stage in the field of ecology and energy.

The condition and composition of air in Lviv are influenced by two main factors: the introduction of pollutants into the atmosphere through various sources and harmful physical effects on it. The latter includes radiation, sound vibrations, noise, and so on. These and other factors disrupt the optimal conditions of the air, which negatively affects human health and the condition and development of animals and plants. The main sources of pollutants in the air of Lviv are as follows: dust — vehicles, woodworking and building materials industry; sulfur dioxide — industrial enterprises, carbon monoxide — vehicles, thermal power plants; nitrogen dioxide — heat power companies; formaldehyde — motor transport, woodworking industry. Today, emissions from mobile sources are the biggest air pollutants in the city. The chemical composition of emissions from mobile sources of pollution is characterized by the predominance of carbon monoxide (up to 74 %), nitrogen compounds, and hydrocarbons (12 % and 11 %, respectively). Today the state of atmospheric air in large cities of Ukraine and, in particular, in the city of Lviv is at an unsatisfactory level. The main problems in this area are the progressive nature of the negative impact on the ecological state of the environment and human health. As there is currently no interactive cartographic material that can visualize the problem of environmental pollution, the main purpose of this work was to create an interactive web map of the quality of life of the population of Lviv in terms of air pollution. To achieve this goal, we collected and systematized geospatial statistical cartographic materials on the ecological conditions of the air in Lviv. The necessary software for the development of an interactive map of air pollution has been selected, and its possibilities have been studied. An algorithm for loading geospatial data into the created web resource has been developed. A template of applications for creating web maps of air pollution in Lviv was selected according to the indicators of 2020, which were measured at 30 crossroads of the city. Thus, two interactive web maps of air pollution in Lviv were developed in the environment «Google My Maps» and «ArcGIS Online».

This paper analyzes the results of the automatic (in situ) recording of the regional transport of pollutants from the large regional coal-fired thermal power plants in the atmospheric boundary layer above the southern basin of Lake Baikal. Due to high stacks (about 200 m), emissions from large thermal power plants rise to the altitudes of several hundreds of meters and spread over long distances from their source by tens and hundreds of kilometers. The continuous automatic monitoring of the atmosphere in the southern basin of Lake Baikal on top of the coastal hill (200 m above the lake) revealed the transport of a large number of sulfur oxides and nitrogen oxides in the form of high-altitude plumes from thermal power plants of the large cities located 70 to 100 km to the northwest of the lake (Irkutsk and Angarsk). The consequence of such transport is the increased acidity of precipitation in the southern basin of Lake Baikal and the additional influx of biogenic nitrogen compounds to the lake ecosystem. The spatial scale and possible risks of such regional transport of air pollution for the lake ecosystem require further closer study.

Retrofitting thermal power plants is a valuable opportunity to guide Taiwan’s electricity generation towards sustainability. Using an existing power plant nearing decommissioning as a case study, we hypothesized about fuel source options for retrofitting the power plant and compared the resulting impact on lifecycle atmospheric emissions. Our use of the lifecycle assessment (LCA) methodology reflected Taiwan’s heavy reliance on the imports and shipping of primary energy sources. We found that after accounting for the contribution of liquefaction and regasification (17%), gas-fired electricity still has significantly lower lifecycle greenhouse gases (GHGs) than coal or fuel oil (FO). In addition, we found that if natural gas (NG) is selected to achieve the greenhouse gas reduction of thermal power, the co-benefit of air pollution reduction can also be achieved at the same time.

The operation of thermal power facilities is associated with the negative impact on the environment and humans of such factors as air, water, soil pollution, electromagnetic radiation, and noise. This article is devoted to improving the noise reduction efficiency of gas and air paths of boilers of thermal power plants. In world practice, to reduce noise in gas-air ducts, dissipative noise silencers are used. The authors propose a new design of sound attenuation elements for dissipative plate-type silencers. The article defines the acoustic and aerodynamic characteristics of noise silencers with new sound attenuation elements. We compare the characteristics of silencers made of new silencing elements and the characteristics of silencers consisting of plates of common design with flat surfaces of the side walls, and demonstrate an increase in acoustic efficiency and a decrease in pressure loss when using the proposed new silencing elements in noise silencers. Recommendations on the use of dissipative plate-type silencers with developed sound attenuation elements for gas-air paths of boilers are given.

During the operation of thermal power plants, boilers, incinerators, vehicles, industrial enterprises for the production of synthetic fatty acids, building materials, paints, textiles, cardboard, paper, as well as resins and products based on them – plywood, chipboards, wood-fiber boards, plastics, etc. The environment is contaminated with formaldehyde. Formaldehyde acts climatically and toxically on local, regional and global processes in the environment and contributes to a high level of air pollution (air pollution index > 14) in almost all industrialized regions of Russia. Products containing formaldehyde, getting into residential and non-residential premises, create an environmental risk to public health. The article is devoted to determining the effect of formaldehyde on woody plants by biochemical and electrophysiological methods and developing a method of reducing the concentration of formaldehyde in the environment by introducing into industrial materials aluminosilicate sorbents of different crystal chemical structure, processed thermo-, in a pulsed magnetic field and under the combined effect of a pulsed magnetic field and temperature effects.

The methodological aspects of the research of the atmospheric air state have been studied, the attention has been paid to biological methods, in particular, to the method of indicating the area of leaf blades, which is easy to use and allows getting reliable results. Taking into account the informative value of the morphometric parameters of the warty birch leaves and the sensitivity of the species to environmental pollution, it is promising to use this species of tree plants as a bioindicator when assessing the ecological status of an urbanized and anthropogenic-transformed environment. The integral index of warty birch leaves asymmetry in the territory with a minimum air pollution was the lowest – 0.0258. The maximum value (0.0914) was investigated in the territory of the “Dobrotvirska Thermal Power Station”, which indicates extremely unfavorable conditions; therefore the plants are in a very depressed state. The average integral index of the fluctuating asymmetry for the warty birch in the region of our studies is 0.0586, which suggests an approximation of the ecological state to pre-critical level. The comparative analysis of the morphometric parameters of the warty birch leaves discovered their uneven resistance to environmental pollution, which manifests itself by decreasing the size, area and biomass (cell material) of the leaves, as well as by increasing the degree of their necrotic damage.

Data recorded in the recently established European Pollutant Emission Register (EPER) is potentially useful for benchmarking of the environmental performance of industrial activity against European practice. Entries in the category of large power plants in the reporting year 2001 for 15 European Union (EU) countries were evaluated to estimate total and fuel specific emissions of NOx, SO2, particulate matter, and CO2. Since the EPER data quality is unknown and since it records only absolute values for emissions and thus does not allow for an eco-efficiency analysis, environmental or sustainability reports made available online by a subset of the operators were sourced to compile a set of specific emissions (per kWh of electricity generated) for the major fossil fuel types, viz. natural gas, fuel oil, coal and lignite. With a few exceptions, notably for PM10 for eight countries and NOx in one case, the large power plant data reported to the EPER is shown to be sufficiently representative of fossil-fuel based generation of electricity and is trustworthy. The fuel mix differs considerably, and together with the varying standard of pollution control technologies, this results in a wide variation in the combustion-related environmental burdens of the generated electricity. Emissions data for South African thermal electricity generation was sourced from Eskom’s 2000 environmental report; in absolute terms they are the highest in this comparison, and in specific terms amongst the three highest per unit of electricity generated from coal.

The purpose of this study is to analyze air pollution in Ulaanbaatar and its causes, and to suggest a crisis management plan for air pollution improvement. Crisis management measures to improve air pollution in the ger region are as follows. First, it is necessary to develop the fuel for heating used in the ger region of Ulaanbaatar and the fuel used in thermal power plants into macektan and anthracite. Compressed fuel emits less soot and burns longer, resulting in lower fuel consumption. Second, it is desirable to introduce a method of replacing the heating system of households in the ger region with the Korean-style ‘floor heating’ method. A household living in a ger consumes 400,000 MNT of coal per year, and installing the ger heating using the Korean-style floor heating method not only saves household costs twice as much, but also protects the economy and health. Third, it is possible to reduce pollutants through fuel improvement in automobiles in Ulaanbaatar City. 80% of vehicles in Ulaanbaatar use benzene, because benzene causes air pollutants such as NO2, CO, CO2, CFC, and lead.

The most pollutant of power plant is sulfur compounds in addition to nitric and carbon mono oxide. Because environmental pollutants influence plant fertility and chemical compounds, therefore this study was done on ten wild Brassicaceae (Alyssum linifolium var. linifolium, Alyssum longistylum, Alyssum marginatum, Choriospora persica, Clypeola lappacea, Conringia perfoliata, Descurainia sophia, Goldbachia laevigata, Isatis kotschyana and Neslia apiculata) taxa collected from the thermal power plant area for bioindication of regional air pollution comparing to controls collected 40 km away from the power plant. Brassicaceae members are important for their ecological, pastoral, medicinal and edible points. Seed width and length max. and their ratio and abnormal seed percentage were calculated. Pollen abnormality and sterility percentages determined using Muntezing’s acetocarmine and light microscopy. Also, their pollen flavonoids were semi-quantitatively assessed using two-dimensional paper and thin layer chromatography. Results showed seeds health and their dimensions reduction in polluted samples in comparison with controls. In C. lappacea significant differences of seed and pollen abnormality and pollen sterility percentages, morin and kaempferol concentrations, between control and polluted samples were observed (P≤0.05). Also, number and kind of pollen flavonoid changes especially increasing flavonoid contents were observed in polluted plants comparing to control. Studying seed and pollen characters can be used as air quality bioindicators.

Cam Pha, the home of three major thermal power plants including Cam Pha, Mong Duong I and Mong Duong II, is one of the most important industrial cities in the North of Vietnam. Air pollution due to stacks emission is the biggest problem threatening Cam Pha City's sustainable development. In this study, the AERMOD modeling system was used to evaluate the impact of the stack emission by the thermal power plants on the ambient atmospheric environment. The maximum 1-HR, 24-HR, 99th percentile and annual average concentrations of TSP, SO2 and NO2 were simulated within the 40x40 km domain of 100x100 m grid spacing with the hourly meteorological data taken from 2018 to 2020. Air dispersion simulation is performed on the observed background gas concentration of the everyday environment. Hourly emission data of 10 primary stack sources of 3 factory groups were used as input data. The simulated spatial distribution of gases indicates the strong fluence of the mountainous topography on the dispersion of stack emission. Results also revealed that the maximum short-term stack emission at ground-level concentrations of SO2 and NO2 are much higher than the national standard, thus raising the risk of severe pollution. TSP pollution is less severe than SO2 and NO2 but still at a dangerous level. Since Cam Pha locates by the East Sea with the prevailing wind is heading northeast and east directions. The annual average concentrations of these pollutants indicate that the high terrain areas at the south and northwest of Cam Pha City, which block the flow of the stack emission, are the most affected regions by exhausted gases from industrial stacks.

Abstract Many countries have put in place, various legislations that govern air emission limits/pollutants from the industries. The common pollutants being monitored are Sulphur Oxides (SOx), Nitrogen Oxides (NOx), Carbon Monoxide (CO), Carbon Dioxide (CO2), Volatile Organic Compounds (VOCs), particulate matters and dioxins. In Malaysia, the regulatory requirement aims to regulate emissions of air pollutants from industrial activities including oil and gas, power plants, waste fuel plants and asphalt mixing plants. One of the emission limits under Clean Air Regulation (CAR2014) is emission level for SOx should be less than 600 mg/m3 (reference condition at 3 % of O2, 273 K, 101.3 kPa) whereby sum of SO2 and SO3 expressed as SOx. Excessive SOx emission can affect both health and the environment. Aligning with the regulation requirement, Group Technical Solution (GTS) under PETRONAS has embarked on assessment of technology solutions to meet the emission limit on SOx emission limit for thermal oxidizers which cover new and existing facilities. This paper describes on the work methodology and approach adopted during the assessment. The objective of the assessment is to determine the suitable process technology to reduce SOx emission in order to achieve the desired emission limit for flue gas at outlet stream of thermal oxidizer. Thorough evaluation was carried out based on proposal submission from various technology providers and Vendors. The selection criteria was developed and established. For existing thermal oxidizers, the assessment is more complex taking into consideration the nature of brownfield project and to ensure the proposed modification has minor impact to operability and maintainability of existing facilities. This study has successfully enabled identification of feasible process technologies such as Caustic Scrubber, Seawater Flue Gas Desulfurization and Ammonia based Desulfurization to meet the desired emission limit at thermal oxidizer outlet for Oil and Gas Industry and supporting environmental protection. The selected technology is varies based on plant/project specific requirement. Among main considerations are the by-product management, consumable and utility consumption as well as compatibility of the technology with existing plant on shutdown requirement.

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.

Being a large consumer of energy resources, the Moscow metropolis significantly changes the climate of its agglomeration. Climatic indicators changing in the medium term have an impact on each of the industries of the metropolis. The most common type of destructive effect is the temperature and humidity deformation of coatings, as a result of which the materials of the building envelope are rapidly destroyed under the influence of positive and negative temperatures. Both thermal pollution and emissions of greenhouse gases and water vapor produce adverse effects. The purpose of this article is to determine the degree of influence of these emissions on climate formation, as well as the possibility of their compensation by Moscow's green spaces. The tasks of analyzing trends in the absolute humidity of air depending on the additional volume of water vapor produced during the combustion of fuel at thermal power plants and in boiler rooms, the functioning of cooling towers, and the operation of motor vehicles are considered in sequence. The dependence of the actual number of clear days on air temperature is analyzed. The months with the longest covered sky are identified. The processes of cloud formation and changes in air temperature depending on the height and conditions of the city are determined. The formation of an area with an increased air temperature at an altitude of 60 to 400 meters above the city territory as a result of heat emissions is demonstrated. The dynamics and reserves of reducing greenhouse gas emissions are analyzed. The efficiency of the implementation of the state policy in the field of energy conservation and energy efficiency, which is focused primarily on the modernization of the power equipment of urban thermal power plants with the installation of modern combined-cycle power units, is shown. The insufficiency of the compensation mechanism of photosynthesis is demonstrated. The ways of climatic adaptation of the megalopolis are shown. Energy-saving measures to reduce gas consumption at sources of thermal energy are identified and the effects of their implementation are evaluated.

The calculation of material and energy flows, the environmental impact on the atmospheric air, water basin and soil has been carried out. The largest mass of harmful substances in wastewater has been observed with the account of the life cycle assessment (LCA) for the mini-CHPs in biogas, the smallest mass in diesel mini-CHPs. During the operation of biogas, gas piston and diesel PI, significant greenhouse gas emissions have taken place because of the fuel combustion. The article considers the issues of thermal pollution in the environment. It has been revealed that the life cycle of the bioenergy installations has a maximum impact on the environment, with the account of the fuel combustion in mini-CHPs with diesel engines. Biogas mini-CHPs have a greater advantage considering the processes of the operation and fuel combustion. The conducted research can help in choosing the type of the engine when designing a mini-CHP.

Heating is one of the major causes of pollution in urban areas, producing high concentrations of aero-dispersed particulate matter (PM) that can cause serious damage to the respiratory system. A possible solution is the implementation of a district heating system, which would decrease the presence of conventional heating systems, reducing PM emissions. The case study considered involves the municipality of Serra San Bruno (Italy), located near a biomass plant, which could play the role of a thermal conversion plant for a possible district heating network. To determine the heating incidence on pollution, the large users in the area were identified. The large users' consumption estimation was carried out, obtaining the thermal energy requirement linked to the residential, which is about 3.5 times that of all the large users. Through air quality measuring devices, PM concentrations were measured for the winter and the summer period. PM emissions were then estimated using emission factors and the decreases in PM concentrations were calculated if part of the domestic users were converted to district heating, compatibly with the possibility of supplying energy to the biomass power plant. The replacement of conventional plants in favor of a district heating network has a positive impact on PM pollution.

The potential of solar energy in Ukraine is high enough for widespread implementation. The most promising method of obtaining electricity is a method of direct conversion of radiation into electricity using solar panels. The production of electricity using solar panels prevents air pollution compared to the production of electricity by thermal power plants and reduces greenhouse gas emissions. The conversion of solar energy into electricity is environmentally friendly compared to traditional energy sources, but at the same time, after their operation, they generate waste that is difficult to utilize.

Air pollution is one of the major problems in the Delhi NCR region due to industrial emissions, traffic congestion, population growth and rapid development. Air pollutants deteriorate the environment, human health, plants and crops. This study focuses on the physiological parameters and yield attributes of paddy and wheat crops in the vicinity of a gas-based national thermal power plant (NTPC) located in Faridabad. Ten sites were selected, including the control site within a 10 km aerial distance from the exhaust chimney stack of the power plant. Major air pollutants, such as NOx, SOx, O3, and PM10, were monitored using Central Pollution Control Board (CPCB) guidelines. The air quality index (AQI) was moderately polluted at the sampling site, while good air quality was observed at the control site. The results showed that the photosynthetic rates were reduced to 46% in paddies and 48% in wheat crops. In the vegetative growth stage of paddies and wheat crops, the stomatal conductance of paddies decreased to 0.11 mmol m-2s-1 compared to 0.19 mmol m-2s-1 at the control site. The transpiration rate ranged from 0.6 to 7.7 μmol/m2/s in paddies and 1.2 to 9.8 μmol/m2/s in wheat crops. The R2 value ranged from 0.702 to 0.985, which shows a strong impact of the air quality index on the physiological parameters of crops. The yield reduction due to air pollution in paddies was 11.6%, and in wheat crops, it was 14.8%. This study also provides an inventory of air pollutants in Faridabad region and their subsequent impacts on crops.

Due to the fact that the potential threat to the health to the public living near nuclear power plants is largely determined by the level of air pollution by radionuclides, identification of the dispersion conditions of pollutants in the atmospheric boundary layer is of great importance in the development of engineering protection means for nuclear facilities. In turn, the engineering protection of nuclear power plants provides for the development of automated radiation monitoring systems and their main components, i. e. atmospheric boundary layer status monitoring systems. When analyzing and predicting the radiation situation in the vicinity of nuclear power plants, the determination of atmospheric dispersion variability parameters over time is essential. This research is aimed at assessing interannual and intra-annual variability of atmospheric dispersion parameters in the Belorussian nuclear power plant siting region based on the atmospheric boundary layer monitoring data. This study has revealed the relative interannual stability of the main average annual atmospheric dispersion characteristics throughout the observation period in 2015-2019. At the same time, the average seasonal values of the atmospheric boundary layer dispersion parameters are characterized by significant fluctuations thereof over the annual course. The feasibility of such monitoring for other potentially hazardous industrial facilities, such as thermal power plants and chemical plants, is also noted.

Aim is to assess working conditions and risks of the general pathological syndromes (RGPS) in employees of the leading occupations of Thermal Power Plants. Materials and methods. Hygienic studies of working conditions were carried out at the workplaces of employees of the main professions of the Thermal Power Plants (TPP) of the Republic of Buryatia. The state of health was assessed using an Automated System of Quantitative Risk Assessment of the main general pathological syndromes (ASQRAS). Results. Study results indicate the predominant noise pollution and dustiness of the air at the workplaces of the TPP. According to the results of ASQRAS, the share of employees of the main professions with a high level of RGPS was 20.83%, which is 2.92 times higher compared to the control group. In the main group, higher levels of risk of developing functional disorders of the respiratory organs and borderline mental disorders were revealed. In the main group the total risks are 1.76 times higher than in the control group. Limitations. Our study had limited options as the acquisition of information on the health status of workers was carried out based on the results of their self-assessment, which may be subject to subjective errors. Conclusion. Thus, the study results indicate the adverse impact of working conditions on the state of health of TPP employees which is confirmed by the results of ASQRAS.

The leading place in the world for environmental protection is currently occupied by the protection of the air basin. And the main sources of atmospheric pollution are industrial enterprises, motor transport and thermal power plants. Thus, there is an obvious need to increase attention to the problems of the innovation sector, mainly in the areas of technical improvement of heat and power industry enterprises. Therefore, the study of the problems of reducing the amount of harmful emissions into the atmosphere, control and regulation of its quality, as well as the study of new various methods of innovative development of thermal power is an urgent task at present, requiring a serious scientific approach. In the proposed work, computer experiments were carried out in the field of innovative energy production technologies (the use of modern "sharp blast" OFA technology) at a specific thermal power facility of the enterprise of the Republic of Kazakhstan. During the experiment, various ways of supplying additional air through OFA nozzles were investigated: OFA=0% (basic version without additional air supply), OFA=10% and OFA=18%. For these three modes, a comparative analysis of the aerodynamics of the furnace part of the boiler was performed according to the obtained distributions of the temperature and concentration fields of nitrogen oxide NO over the entire volume of the combustion chamber. The results obtained were compared with experimental data obtained during experiments conducted directly at the CHP.

The main tendencies in the nature air pollution in Moscow from thermal power plants are considered. Emission reductions from CHP high rates are determined by a change of the main factors balance from the fuel mix capacity utilization to upgrading facilities equipment utilization optimization. On the Ochakovskaya CHP example was shown that by reducing emissions the concentration of contaminants decreased. However, the spatial structure of the pollution area has remained. Here, the low concentration zone, which is associated with the wind shadow effect, characterized of high sources, is replaced by a zone of maximum concentration, that in dangerous wind conditions velocity increases to more than 6 times. In addition, there is one zone of pollutants accumulation, within which their concentration increases by more than 7 times. For more rapidly settling suspended particles, there is the maximum concentration near the source (0.8–1.5 km). For well-scattering nitrogen oxides, sulfur dioxide and carbon monoxide are reached the maximum concentration farther from the source of emissions (5.5–6.5 km).

This study focused on gaseous pollution caused by exhaust gas from AL-Zubaydiah thermal power plant. Study gases included sulfur dioxide (SO2), nitrogen oxide (NO), carbon oxide (CO) and hydrocarbon (HC). The concentration of gas measurement is conducted during six months from January until June 2017. Nova 600 series portable devise and G450 confined space gas detector was used for measuring gas concentration, which emitted from the chimney of the thermal power station with an interval of 100m and into the path of smoke for a distance of 1400 m. The prevailing wind direction and temperature were taken into consideration during the study and their impact on the gas distribution. Four readings have been taken in each station during each month for all gases under study. The results showed that less gas concentrations were near the power station and then getting more gas concentration away from the station and higher concentrations are obtained at a distance of 900 m from the power station at ground level. Results indicated that sulfur dioxide concentrations recorded were higher than allowed in the Iraqi and American standards in most locations around the station. The highest concentration recorded at 900 m from the power station with value 597.3968 μg/m3, which is higher than the limitation of Iraqi and international specifications (150 μg/m3). This high concentration of SO2 is due to the crude oil from the Ahdab field with high rates of Sulphur that used as fuel in the generation process. These high concentrations of sulfur dioxide cause problems on the growth of plants and human health and viability of the soil in the coming years. Nitrogen oxide gas concentrations also were high and outside the upper limits allowed and were worth 131.38 μg/m3. The rest of the gas concentration (CO and HC) were acceptable and within the Iraqi standard. To preserve the environment in the region and within the limits of the allowed values globally requires a search for another source of fuel with a low percentage of sulfur and using modern technology for burning to reduce emissions of nitrogen oxides.
