【 摘 要 】

Gas filling stations are an integral part of the urban economy and the life of the modern city. The gas stations are situated in compliance with the regulatory and technical requirements, as a rule, based on terms of their ecological and environmental safety. However, gas stations are located in close proximity to residential habitation's buildings. These gas stations are sources of pollution of the atmosphere of urbanized areas obviously. At the same time, the normative dimensions' values of the sanitary protection zone are not allowed to decrease. In this case gas stations exert a negative impact on the residential habitation's areas of the cities. It was determined maximum-one-time and gross annual average emissions' volumes from gas stations using of current calculating methods. It is found that the maximum emissions of ingredients are preceded for the filling draining gasoline from road tanker trucks to storage tanks. It was having been fulfilled experimental studies to determine the concentrations of hydrocarbon vapors in residential buildings in the areas of gas stations in Stavropol and Volgograd. It reveals exceeds acceptable concentrations' limit of pollutants for mention above technical operation of in the air at the border of the SPZ of filling stations and residential buildings. Analysis of the data of the calculation monitoring showed the same that field studies. The most promising for reducing gas vapor emissions' was applying absorptive device for trapping gasoline vapors in industrial set up. The high efficiency of gas vapors capturing in the proposed absorptive apparatus was confirmed by successful test of industrial set up.
