Документ A study of air pollution with formaldehyde along the highways in Kyiv city(2018) Voloshkina, O.; Sipakov, R.; Zhukova, O.; Bereznitska, J.The problem of air pollution in the cities of Ukraine was described. The methodology of calculation of hydrocarbon emission on automobile overpasses and crossroads of Kyiv was suggested. By the number of bands, the number of cars was determined. The calculation has shown that at the same time near 300 cars can be on the overpass during peak hours. The average concentration of formaldehyde according to the calculations and observation data in 2016 was presented.Документ Risk of atmospheric air pollution by formaldehyde in urban areas from motor venicles(2019) Voloshkina, O.; Sipakov, R.; Tkachenko, T.; Zhukova, O.The work is devoted to the issue of risk management for the health of the population in urban areas in case of atmospheric air pollution by motor transport. In this study, the level of risk is determined on the basis of concentrations of formaldehyde molecules, which are formed as secondary air pollution as a result of photochemical transformations in the air under steady meteorological conditions. In the estimation of the amount of hydrocarbon emissions from road transport, which is simultaneously at the traffic junction, a mathematical model which is based on the theory of a convective jet on a warm surface and which allows obtaining parameters of the contaminated dome of air formed over this area was used. The proposed risk management scenario allows searching for optimal managerial decisions at the municipal level for a number of scientific and practical tasks of the city in shaping its environmental policy.
