Abstract

Environmental issues in cities are some of the causes of reduction in the average life expectancy of people, increase in the incidence and mortality of the population. According to scientists, health of the urban population is 20% dependent on the state of the natural environment. Urban residents are more likely to suffer from cardiovascular diseases, respiratory diseases, and blood circulation problems. In the course of urban development, people have a significant negative impact on the biosphere, changing it and being a part of it, they experience the consequences of these changes on themselves. This situation is complicated by the lack of a unified approach among civil engineers, architects, hygienists and environmentalists in the matters of organizing a residential environment. The article focuses on identification and analysis of sources of pollution affecting the air basin of modern cities. A comparative analysis of the transport and construction industries and their role in urban pollution is carried out. Using the example of the city of Moscow, calculations have been made and the indicators of the wind speed variation along the height of the building have been determined, depending on the type of terrain. These data allow assessing the formation of air exchange in urban areas and can be used to solve the problems of improving the urban environment.
