Trends Of Forming Urban Environment's Air Pollution Level

Abstract

Trends of forming the level of air pollution of urban environment are defined through performing analyzis of 10-year study of air, based on a range of meteorological parameters and chemical composition of air. Among the considered meteorological parameters we have identified the most important, they are: direction of admixtures transfer, the transfer rate, the air temperature, cyclonic activity and meteorological stability of the research area. Among the anthropogenic factors we have distinguished and provide characteristics for pollution sources, architectural planning of the researched area, as well as have performed analysis of pollutants. To determine the level of air pollution by using  modern techniques, partial pollution index and integrated pollution index as well as the relative increase in pollutant concentrations (common and specific) were calculated. As a result of the the study it was found that increased levels of air pollution are caused by benzene (if speak about specific substances) and formaldehyde (if speak about common substances). Also trends of air pollution are identified in accordance with wind rose and architectural planning; trends of forming the maximum level of pollutants in the air of urban environment are identified.
