Документ The Role of “Green Structures” in Reducing the Environmental Footprint of Urbocenoses(2018) Tkachenko, T.; Voloshkina, O.The modern problem of urbocenoses is associated with an increase of the environmental footprint, the main indicator of which is the concentration of CO2 in the atmosphere. One of the ways to reduce carbon emissions is to increase biomass through the «green structures». Nowadays, there are insufficient methods for calculating the accumulation of biomass and sequestration of CO2. As a result, new methodological approaches are proposed.Документ “Green structures” as a tool for reducing the environmental risks of urban ecosystems(2019) Tkachenko, T.; Voloshkina, O.Modern urbocenosis is an unstable artificial ecosystem. Under the influence of natural and man-made factors, urbocenoses are subject of environmental, economic and social risks. Optimal using and restoration of natural areas is one of the ways to reduce the risks of urbocenoses, a way to increase their stability and sustainable development.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.
