Abstract

According to numerous studies, even with a relatively low level of exposure to adverse environmental factors, risk of health deterioration may occur. Both the amount of harmful emissions and their chemical composition directly affect the level of air pollution. The article considers the issues of environmental pollution of an urbanized area by automobile exhausts. The most polluted city is Vladikavkaz that is the capital of the Republic. There the main stationary sources of pollution are located and the largest number of vehicles is concentrated. The dynamics of increasing the number of vehicles in the city of Vladikavkaz over the past 10 years and a corresponding increase in harmful emissions from combustion products are shown. For the same period of time, the amount of emissions of harmful substances into the atmosphere from stationary sources has been considered in order to compare their contribution to total pollution compared to road transport. Based on the explorations, it is shown that the main source of pollution in terms of emissions in the Republic of North Ossetia-Alania is road transport. The number of vehicles is increasing year after year, amid a decrease in total emissions of pollutants from stationary sources.

Highlights

One of the most acute environmental problems of our time is environmental pollution, which leads to adverse effects on public health, especially in urban areas [1].According to numerous studies, even with a relatively low level of exposure to adverse environmental factors, risk of health deterioration may occur [2]
The results obtained allowed us to establish that there is a direct relationship between the flow of cars and air pollution, the most intense pollution was noted in the area of the “Druzhba” cinema and the Arkhonsky intersection
The data obtained indicate a steady trend of increasing atmospheric air pollution from the increasing negative impact of vehicle emissions, which has a bad effect on the health status of the population

Summary

Introduction

One of the most acute environmental problems of our time is environmental pollution, which leads to adverse effects on public health, especially in urban areas [1].According to numerous studies, even with a relatively low level of exposure to adverse environmental factors, risk of health deterioration may occur [2]. The peculiarity of the influence of various harmful substances on the health of the population is that even for low concentrations, the harmful effect on the human body becomes significant with prolonged exposure [3]. Both the amount of emissions of harmful substances and their chemical composition directly affect the level of air pollution [4,5,6,7]. In rural areas of the Republic, there is a stable satisfactory state of atmospheric air due to the lack of large industrial enterprises and a large number of vehicles
