Item The influence of terrain, climatic conditions and factors on the atmospheric air monitoring system, based on the implementation of eu legislation on the example of Lviv region(Видавництво Львівської політехніки, 2023-02-28) Kravets, Ihor; Malovanyy, Myroslav; Tymchuk, Ivan; Shkvirko, Oksana; Department of Ecology and Natural Resources of the Lviv Regional State Administration; Lviv Polytechnic National UniversityThe article is devoted to the influence of terrain, landscapes, and meteorological conditions on the establishment of air quality monitoring points in the relevant territory of the Lviv region. The main factors affecting the distribution of the concentration of pollutants in atmospheric air during the design of air monitoring stations have been determined. It was established that the level of the surface concentration of pollutants increases with an increase in the power of the emission source, the density, and size of impurity particles, and decreases with an increase in the height and radius of the orifice of the emission source, the temperature of the emission, and the rate of release of impurities from the source.Item Assessment of the impact of the paper enterprise on the environment(Видавництво Львівської політехніки, 2020-10-10) Khomko, Natalia; Lviv Polytechnic National UniversityPulp and paper enterprises are of great importance for sustainable economic and environmental development of certain regions and the economy of Ukraine. Man uses many natural resources during the lifetime, creating a burden on nature. As the world's population increases, this load increases, leading to a shortage of resources and deterioration in the environment. The main activity of Kokhavynska Paper Mill PJSC is the production of sanitary products for the domestic market and export. Rational use of secondary raw materials helps to cut the use of forest resources and reduce the amount of waste paper utilized in landfills. 15291.76 t of pollutants from the sources of the enterprise emissions enter the air each year. A total of 9 standardized and 3 non-standardized substances (greenhouse gases) are released into the atmosphere, namely nitrogen oxides, carbon monoxide, nitrogen (1) oxide (N2O) (greenhouse gas), carbon dioxide (greenhouse gas), methane (greenhouse gas), iron and its compounds, manganese and its compounds, hexavalent chromium (expressed in terms of chromium trioxide), gaseous fluorides, hydrogen sulfide, saturated hydrocarbons C12-C19. There is no excess of the established maximum concentration limits at all emission sources at this enterprise. To assess the impact of the enterprise on soils, the content of heavy metals Zn, Cr (VI), Co, Cu, Pb, Mn, and Fe at the border of the sanitary protection zone of the enterprise was determined and the maximum multi plicity of the excess of MPC of heavy metals was calculated. The content of heavy metals in the selected soil samples was determined using a spectrophotometer atomic absorption C-115-M1. Evaluation of soils for heavy metals showed that the soils at the border of the sanitary protection zone of the enterprise are contaminated with heavy metals. The maximum multiplicity of the excess of the MPC of heavy metals in the soil is 1.04 times for lead; 0.43 times for zinc; 0.37 times for chromium; 0.93 times for copper; 1.85 times for manganese; 0.35 times for cobalt. Maximum concentrations of heavy metals exceed their background content: 1.6 times for lead; 1.8 times for zinc; 1.16 times for chromium; 0.77 times for copper; 3.9 times for manganese; 9.7 times for iron; 1.2 times for cobalt.Item Assessment of the atmospheric air pollution level in Kyiv(Lviv Politechnic Publishing House, 2019-02-26) Barabash, Olena; Khrutba, Viktoriia; National Transport UniversityGroups of plants, that regulate gas composition and the degree of air pollution, play a significant role in solving a complex spectrum of problems in the development of the modern city. The system “plant organism-urban environment” is indicative for the detection of dust pollution in atmospheric air of urban areas, manifesting the response of higher plants (morphological, anatomical, biochemical changes) used in urban landscaping.Item Scientific priorities of the development of environmental research in Kyiv National University of Construction and Architecture. The life path of Professor Voloskhina O. S.(Lviv Politechnic Publishing House, 2019-02-26) Tkachenko, Tetyana; Kyiv National University of Construction and ArchitectureThe article deals with the main scientific priorities of the development of environmental research in Kiev National University of Construction and Architecture under the leadership of the Head of the Department of Labour Protection and the Environment, Doctor of technical sciences, Professor Voloshkina O. S. Current priorities of her scientific research are: management of ecological safety of atmospheric air in the area of motorway overpasses and formation of photochemical smog; increase in the environmental and energy efficiency of “green building"; introduction of “green structures” into the domestic construction in urbocenoses during the reconstruction and construction of residential and industrial premises; ecological issues in the construction industry.Item The key aspects of atmospheric air ecological monitoring concept formation at the urban systems level(Publishing House of Lviv Polytechnic National University, 2017) Bakharev, Volodymyr; Marenych, Andriy; Kremenchuk Mykhailo Ostrohradsky National UniversityThe key aspects of atmospheric air ecological monitoring concept formation on the urban system have been analyzed. The principal scheme of concept construction has been proposed. It has been defined that the concept has to be built on the anthropocentric approach. The samples of atmospheric air ecological monitoring unsolved issues on the urban system of the town of Kremenchuk (Ukraine) have been taken to concretize the integral parts of the concept with defining goals, objectives, statistic results and dynamic indicators of the concept implementation.
