Introduction. The present time is characterized by the rapid development of cities and, as a consequence, the aggravation of a whole set of problems. Cities provide a fairly high standard of living for the population, satisfy their needs, but at the same time, they are the center of the significant environmental problems. All this is due to the excessive concentration of transport and economic facilities in relatively small areas. Goals and objectives. The aim of the work is to assess the level of impact of vehicles in terms of noise pollution and air pollution in Belgorod Construction of noise maps of individual microdistricts of Belgorod and calculation of emissions of the main pollutants into the air from traffic flows, which will make it possible to predict and identify areas of the urban environment where the established sanitary and hygienic standards are exceeded. Methodology. The study of the noise situation in certain areas of the city was carried out in accordance with the requirements of GOST 20444-2014 and GOST 53187-2008. The main characteristic was the equivalent sound level of traffic flows, calculated from the results of instrumental measurements of the noise level. To assess air pollution, calculations were carried out according to the methodology for calculating emissions of pollutants into the atmosphere by vehicles on city highways. Field observations to study traffic flows were carried out in the daytime. Results and its discussion. The obtained data on the noise level on the territory of the studied microdistrict were used to compile a noise map, which makes it possible to identify areas of the urban environment that do not meet sanitary and hygienic requirements for the noise factor. Calculation data for emissions of harmful substances from vehicles can be used to create environmental passports and are useful in making decisions to reduce the negative impact of transport on the environmental situation of industrial cities. Conclusion. The study of noise pollution and atmospheric air pollution, the source of which is motor vehicles, in an urban environment, makes it possible to develop a complex of health-improving, environmental, urban planning measures and a number of architectural and planning solutions aimed at reducing the level of noise pollution and air pollution in these areas. Keywords: urbanized areas, vehicles, noise pollution, emissions of harmful substances

Emissions Of Harmful Substances

Modern studies on the impact of road transport on air pollution indicate a steady increase in negative impact, reflected in an annual increase in emissions. In 2017, they reached the level of 14.5 million tons, which exceeds the level of 2012 by 14 %, while despite the tightening of re-quirements for cars, an increase of 2.5 % was recorded only in the last year [1]. Modern cars do not cause significant harm to the environment, unlike earlier ones, however, the share of relatively new cars is small, about 15 % of the fleet [2]. Positive results in terms of reducing gross emissions of harmful substances, especially in cities, can be achieved by reducing or modernizing the fleet of vehicles owned by both legal entities and individual owners. Weighted and socially responsible decisions in the field of modernization of the fleet of vehicles of individual owners can be made on-ly after a detailed analysis of not only the age structure of the fleet, but also the trends in the limit of service life, as an indicator of the owner’s willingness to voluntarily stop using the car.

The aim of this paper is to evaluate the air and thermal pollution in the southern suburbs of Riyadh, where people are suffering from poor air quality due to the rapid development of the industrial facilities in the area. The study involved the distribution of questionnaires to 405 residents living in that area in order to obtain their opinions about air pollution. In addition, land surface temperature and 12 components of air were measured at 18 points. In addition, the air quality data from 2016 to 2020 for Al Khaldya and Southern Ring Road air stations were assessed. Al Misfat (Oil Refinery) and the Second Industry City are significant contributors to air pollution and also result in the urban heat island effect from high temperature due to factories and industrial activities. However, all the measured components of air quality are lower than the standard limits except the element particulate matter (PM)10, which exceeds the standard limits in several parts of the study area and during several months of the year. This can surely have a negative impact on the health of residents. At the same time, this study found that the preventive measures taken to stop the spread of COVID-19 infections have led to a positive impact in the area in terms of improvement in air quality.

The combination of factors that determine the level of atmospheric pollution, the priority harmful component of which is dispersed particles, has a random and unique character for the urbanized territory of «InnoKam». Therefore, to study the process of atmospheric pollution of this urbanized territory, an approach was used that takes into account that the content in the air of dispersed particles of motor transport and industrial origin depends on the nature of the processes of upsurge, propagation and deposition, which are determined by the fractional composition of particles, structural and functional parameters of road traffic flows., climatic and urban features of the territory and meteorological conditions. The aim of the study is to reveal the patterns of air pollution in the urbanized territory of «InnoKam» with dispersed particles, which is relevant and necessary for the effective implementation of measures to create a favorable and comfortable urban environment, as well as the attractiveness of the innovation and production center for visiting specialists and investors. Regularities of air pollution in the urbanized territory of «InnoKam» by dispersed particles, which is formed when pollution from road traffic flows are superimposed on the polluting background of industrial enterprises, have been investigated. Motor transport streams are both independent sources of the formation of dispersed particles, and a source of upsurge and spread of dispersed particles over considerable distances beyond the boundaries of highways. To reveal the regularities and obtain the corresponding mathematical models, both instrumental methods based on measuring the content of dispersed particles DCh 10 and DCh 2.5 in the atmosphere of the investigated urbanized territory, and statistical analysis of experimental data were used. Mathematical models have been obtained that, with a high degree of reliability, describe the regularities of air pollution by dispersed particles for the urbanized territory of «InnoKam», which is the scientific value of the results obtained. The practical significance of the results obtained lies in their use for predicting and compiling air pollution maps with dispersed particles in all parts of the urbanized territory of «InnoKam» in order to develop and substantiate measures to create a favorable and comfortable urban environment. The main activities are analyzed and divided into three groups, based on the specifics of the sources of formation of dispersed particles (vehicles, traffic flows, highways). The ranking of measures for the effectiveness of reducing air pollution by dispersed particles is the object of further research.
