ASSESSMENT OF THE LEVEL OF ATMOSPHERIC AIR POLLUTION BY MOTOR VEHICLES THE CONCENTRATION OF CARBON MONOXIDE

The atmosphere has an intense impact not only on humans and biota, but also on the hydrosphere, soil and vegetation, geological environment, buildings, structures and other man-made objects. Therefore, the protection of atmospheric air and the ozone layer is the most priority environmental problem and it is paid close attention in all developed countries. the Purpose of the study is to Determine the pollution of the surface layer of the atmosphere in some parts of Kazan by vehicle emissions. Results: the Results of studies and calculations show that the amount of carbon monoxide emissions exceeds the norm from 4-15 times. The risk coefficient on the investigated section of Academician Parin street is "high" (5-7), on the section of Pushkin street the risk coefficient is "extremely high". The current situation of anthropogenic impact has a negative impact on the health of the population living in the area of these parts of the city. Daily contact with a negative atmospheric background increases the risk of diseases such as cardiovascular diseases, respiratory diseases, organ dysfunction, CNS depression, dermatological diseases (dryness, peeling of the skin).
