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.

Minor towns with population size of 50-100 thousand people are much rarely studied in regards of the ecological-hygienic assessment of human environment, in spite of the fact that they are characterized by specific ecological problems. The objective of the study was the hygienic assessment of the impact of urban environment on population health status in Tikhvin and Gatchina towns of the Leningrad region. Morbidity rate in the population of Tikhvin and Gatchina in 2005-2015, atmospheric emissions of industrial enterprises, findings on monitoring for both atmospheric air pollution and centralized drinking water supply, as well as motor transport noise levels were studied. Population health risk stipulated by industrial emissions and noise exposure was calculated. Statistical data treatment with correlation analysis of the relationship between environmental pollution indices and population morbidity was carried out. The study revealed increased atmospheric air pollutant concentrations in Gatchina, which might be connected with motor transport effect. Acute non-carcinogenic risk levels resulting from air pollutants are on the borderline of the admissible level, while in Tikhvin town those values are significantly lower. Estimated concentrations of atmospheric pollutants produced by industrial emissions are by 1.5-2 times lower than the actual levels shown by monitoring. Noise levels and predicted health risks in Gatchina are on the borderline of the admissible level, while in Tikhvin they are significantly reduced. The statistically significant gain in the general primary morbidity rate indices due to respiratory diseases in Gatchina town, correlated with atmospheric air pollution, was revealed. Our study showed that despite the presence of large industrial enterprises in studied towns, motor transport proved to be the key factor that forms air pollution and noise load, more typical of large cities.

A feature of the tasks associated with the spread of harmful substances in the natural environment is the presence of a large number of parameters that affect the migration of im-purities. Mathematical models of varying complexity are used to describe such processes. The task of air monitoring by industrial enterprises is to collect, process the parameters of atmospheric pollution in the local area and develop, based on the results, conclusions regarding decision-making on the ecological state of both the industrial site and adjacent residential areas. An improved method of data approximation using piecewise polynomial regression is presented. The proposed algorithm makes it possible to increase the adequacy of determining the boundaries with a sharp change in the concentration of a harmful substance, improves the accuracy of the constructed models of the release of a substance into the atmospheric air and more accurately assess the scale of pollution. The developed methods allow visualization of the obtained data to increase the information content in assessing the pollution of a certain area.Along with mathematical models, when assessing the level of pollution, geographic in-formation systems (GIS) are used as a powerful tool that provides: collection, storage, pro-cessing, display of data, analysis, assessment, forecast of the state of the environment of a territorial community. The methods and algorithms described in the article form the basis of information technology and software for solving the scientific and technical problem of visual and analytical analysis of atmospheric air pollution data in the GIS «AirNorm». With the help of this GIS, the results of a computational experiment carried out on the indicators of the level of emission of NH3 for the source V-109 at the State Research and Production Enterprise (GNPP) «Zirkoniy» m. Kamenskoye were obtained and presented.

В статье исследовано состояние загрязнения атмосферы и заболеваемости населения на территории г. Владикавказа за пятилетний период. Установлена тенденция к снижению выбросов в окружающую сре- ду главным образом за счет уменьшения объемов производств и выполнения природоохранных меропри- ятий на промышленных предприятиях города. Вместе с тем, отмечается рост количества автотранспорта и его техногенная нагрузка на среду неуклонно увеличивается. State of air pollution and the incidence of population on the territory of Vladikavkaz city for the five-year period are investigated in the paper. The tendency of reduction of emissions into the environment (mainly due to the reduction of production volume and implementation of environmental activities at the industrial enterprises of the city) is stated. At the same time, number of vehicles and corresponding anthropogenic impact on the environment are steadily increasing

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

COVID 19 is undeniably one of the deadliest diseases that humanity has ever seen. It continues to affect the lives and livelihood of people appallingly across the world. Maximum discussions focus towards the apprehension of catching the infection, dwelling in homes, overpopulated nursing homes and shut down of all kinds. But, here let’s discuss the positive side of COVID 19 pandemic.As COVID 19 has spread its influence all over the world, affected countries have either announced lockdown or have implemented severe restrictions in their respective countries. Because of this, everyone dwells in their homes. Thus, exercising social distancing and functioning from home. All of the above is directed at restricting the transmission of coronavirus and expectantly ostracising the fatality from COVID 19. These transformations have also brought about some unanticipated emanations; some good things have come out of the pandemic as well. Positive effects of COVID 19 are seen on reduced road traffic, and road traffic accidents lowered levels of air pollution which has to lead to lowered heart attack rates and rejuvenating environment. Crime rates have fallen, and expenses are reduced in most places. Community action, communication amongst families, behaviour, sanitation, hygiene, online and distance education has positively impacted by COVID 19 pandemic. COVID 19 despite a bane for humans, can be thought of a boon for living beings. The habitats and elements have been purified with the stringent use of petrochemical products. To breathe fresh air and to consume purified water is a boon by itself. Now, it is time for humans to lead a caring life to every bounty bestowed on them by Nature. This thoughtful and considerate life will give hope for a healthy, stress-free life.

The protection of the environment and people’s health from negative influences of the pollution of air as a medium of the environment requires constant observing of the air quality in accordance with international standards, the analysis of emission and imission of polluting matters in the air, and their connection with the sources of pollution. Having in mind the series of laws and delegated legislations which define the field of air pollution, it is necessary to closely observe these long-term processes, discovering cause-and-effect relationships between the activities of anthropogenic sources of emission of polluting matters and the level of air degradation. The relevant evaluation of the air quality of a certain area can be conducted if the level of concentration of polluting matters characteristic for the pollution sources of this area is observed in a longer period of time. The data obtained by the observation of the air pollution are the basis for creation of the recovery program of a certain area. Vranje is a town in South Serbia where there is a bigger number of anthropogenic pollution sources that can significantly diminish the air quality. The cause-and-effect relationship of the anthropogenic sources of pollution is conducted related to the analysis of systematized data which are in the relevant data base of the authorized institution The Institute of Public Health Vranje, for the time period between the year of 2012. and 2017. By the analysis of data of imission concentrations of typical polluting matters, the dominant polluting matters were determined on the territory of the town of Vranje, the ones that are the causers of the biggest air pollution and the risk for people’s health. Analysis of the concentration of soot, sulfur dioxide and nitrogen oxides indicates their presence in the air of Vranje town area in concentrations that do not exceed the permitted limit values annually. The greatest pollution is caused by the soot content in the air, especially in the winter period when the highest number of days with the values above the limit was registered. By perceiving the influence of natural and anthropogenic factors, it is clear that the concentration of polluting matters can be decreased only by establishing control over anthropogenic sources of pollution, and thus it can be contributed to the improvement of the air quality of this urban environment.

Today, the design and remodeling of urban environments is being sought in order to achieve green, healthy, and sustainable cities. The effect of air pollution in cities due to vehicle combustion gases is an important part of the problem. Due to the indirect effect caused by the Covid-19 pandemic, political powers in Europe have imposed confinement measures for citizens by imposing movement restrictions in large cities. This indirect measure has given us a laboratory to show how the reduction in vehicle circulation affects in a short time the levels of air pollution in cities. Therefore, this article analyzes the effect in different European cities such as Milan, Prague, Madrid, Paris, and London. These cities have been chosen due to their large amount of daily road traffic that generates high levels of pollution; therefore, it can clearly show the fall in these pollutants in the air in the analyzed period. The results shown through this study indicate that the reduction in combustion vehicles greatly affects the levels of pollution in different cities. In these periods of confinement, there was an improvement in air quality where pollutant values dropped to 80% compared to the previous year. This should serve to raise awareness among citizens and political powers to adopt measures that induce sustainable transport systems.
