ECOLOGOCAL CONTROL OF ENVIRONMENTAL IMPACT POLLUTANT EMISSIONS OF PRODUCING ASPHALT CONCRETE

Abstract

With each passing year, the issue of studying the state of atmospheric air and the impact of pollutant emissions becomes increasingly relevant. For this reason, in modern conditions, economic enterprises, including asphalt concrete production facilities, must be studied and controlled to assess their environmental impact. This article presents the results of research on the features of the technological process of asphalt concrete production, which belongs to the 2nd group of enterprises. An analysis of the sources of pollutant formation at the studied enterprise located in the Kovelsky district of the Volyn region is conducted. The methods for determining concentration indicators and emission measurement techniques are described. The calculation of atmospheric pollution on a computer is demonstrated. The results of calculating pollutant emissions into the atmosphere are described. An analysis of the types and volumes of emissions of pollutants into the atmospheric air from stationary sources is carried out. It was found that stationary sources of the enterprise emit 10,266 tons/year of pollutants into the atmospheric air, of which 2.76 tons/year are dangerous. Concentrations of pollutants in the atmospheric air, taking into account the existing background pollution, at the boundary of the normative sanitary protection zone do not exceed hygienic standards.The results of calculating ground-level concentrations, taking into account pollutant emissions at the boundaries of the sanitary protection zone, are presented, and measures to improve the environmental situation are proposed. According to the research results, it has been established that pollutant concentrations in the atmospheric air, considering the existing background pollution, do not exceed hygienic standards at the boundary of the sanitary protection zone. The quality of atmospheric air meets the permissible pollutant content, at which there is no negative impact on human health and the environment.
