POLLUTION OF THE ATMOSPHERIC AIR BY PETROL STATION EMISSIONS

Introduction. Air pollution is one of the urgent problems of our time. Pollutants entering the human body have a negative impact on the work of internal organs, mucous membranes, immunity, and cause the growth of cancer. In Russian cities, the main sources of anthropogenic air pollution are industrial enterprises, motor transport, oil production and oil-refining, etc. In this paper the pollution of atmospheric air emissions of oil products from the use of petrol stations on the example of the city district of Nalchik (South of Russia) is considered. Materials and methods of research. For calculation of the emission characteristics a methodological guidance for estimating pollutants’ emissions into the atmosphere from reservoirs are used. To assess the degree of emissions’ negative impact, there are carried out calculations under the program «Ecologist-4.5», which implements methods of dispersion of pollutants’ emissions in the air. All these methods and the program are approved in accordance with the established procedure. Research results and their discussion. The maximum-single and annual emissions of motor fuel vapor components are given. Results of calculations of pollutants’ dispersion are described, as an example the map of dispersion of one of pollutants is showed. It was found that at the border of the living zone there is no excess of the maximum permissible concentration for all substances. Conclusions. The results show that the annual emission of pollutants even at one of the 25 petrol stations of the city district of Nalchik is significant. Therefore, it is necessary to do much work to reduce it.
