Stationary Sources

The risk of chemical pollution is assessed by the level of its possible negative impact on the atmosphere, soils, groundwater and surface water, vegetation, animals and humans. The state of atmospheric air in Kharkiv and Kharkiv region is analyzed and it is revealed that atmospheric air pollution comes from mobile and stationary sources of pollution. One of the main sources of pollution is thermal power plants and oil and gas companies. The largest number of emissions from stationary sources is in Zmiiv, Krasnograd, Balakliia, Chuguiv districts and Kharkiv. The largest number of emissions from mobile sources is observed in Kharkiv and Derhachiv districts. The most polluted areas of the city of Kharkiv were identified, especially the central district and the area of the railway station, and the causes of pollution were established. As a result of comparison of the accepted maximum admissible concentrations of chemical substances in Ukraine, the USA and the countries of the European Union it is revealed that the Ukrainian norms are stricter. An analysis of emissions since 1990 found that their 9,14-fold reduction was due to a reduction in production and the closure of some enterprises as a result of the collapse of the Soviet Union. The sharp drop in emissions since 2013 is also due to the economic crisis and hostilities in eastern Ukraine. The reduction of emissions is explained not only by the reduction of production volumes, but also by the implementation of air protection measures carried out at the enterprises of the city and the region. There is a close link between pollutant emissions and gross domestic product (GDP) production, which can be used in the future to forecast emissions. Measures aimed at improving the state of atmospheric air in Kharkiv region and the city of Kharkiv are presented.

Radioactivity Measurements

Serbian thermal power plants (TPPs) produce siliceous fly ash from lignite in the quantity of approximately 6 million tons per year. The potential market for the use of fly ash is operational, but for the time being, only used by cement producers. Fly ash radioactivity could be one of the major points of concern when larger use of fly ash is planned, particularly in the Serbian construction industry. Radioactivity measurements have been conducted regularly for decades. This paper presents the results of a ten-year fly ash radioactivity measurements at the Nikola Tesla B TPP located in Obrenovac. In addition, the paper compares the natural radionuclides coal content data combusted by the Nikola Tesla B TPP boilers coming from the Kolubara Basin and ash created during coal combustion. Fly ash created in the Nikola Tesla TPPs boilers is characterised by the increased concentration of the natural radionuclides content compared to coal. This is the so-called technologically enhanced natural radioactivity (Technologically Enhanced Occurring Radioactive Material - TENORM) of industrial waste, whereas the average specific activities: 232Th in coal amount to 25.2 Bq/kg, and in fly ash and coal 84.2 Bq/kg and 238U 38.3 Bq/kg, respectively. Following the obtained natural radionuclides content results it may be concluded that the Nikola Tesla B TPP ash may be disposed into the environment. Ash may be used also in the construction industry (civil engineering). In building construction applications, ash share as the additive to other building materials depends from its physical and chemical characteristics, as well as from the radionuclides activity: 266Ra, 232Th and 40K. Unlike the thermal power plants regularly (once a year) testing the specific natural radionuclides activity in the combusted coal and boiler fly ash, Electric Power Industry of Serbia has not performed large-scale investigations of the natural radionuclides content in coal within the Kolubara Mining Basin. Natural radionuclides content in fly ash is compared to the combusted coal some 3 - 4 times higher and may present a limitation for applying ash in the construction industry. In view of the above, and considering the construction industry interests in using the Nikola Tesla B TPP ash, regular investigations of the natural radionuclides content in ash created in the thermal power plants should be carried out, together with the Kolubara Mining Basin coal combusted by the Nikola Tesla B TPP and other PE EPS thermal power plants. The current Kolubara Mining Basin coal characteristics investigation programme should be supplemented by the natural radionuclides content of the uranium (238U, 226Ra) and thorium series (232Th) and potassium 40 (40K).

The City

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.
