Impact of climate change on air quality near petrochemical plants

The article investigates the problem of the influence of anticyclone blockings on the chemical composition of atmospheric air near a petrochemical industry enterprise.As an object of study, data arrays of pollutants registered in the emitted gas cloud of the production of agidols and in the residential area of the city were selected.Based on data from the Missouri Climate Center (USA), an analysis was made of the characteristics of anticyclone blockings in the study area.An increase in the intensity of the phenomenon over the period 1990-2021 was revealed.The results of the analysis of blocking seasonality are obtained.Based on the data of environmental monitoring of the area, the effect of air temperature on the change in the concentration of o-C 8 H 10 , m,p -C 8 H 10 , C 6 H 6 , C 6 H 5 OH, CH 3 OH, C 6 H 5 -CH 3 , C 6 H 5 -C 2 H 5 was studied, which made it possible to identify the effect of anticyclone blocking, wind regime and chemical processes on the value of the concentration of a substance in the air.The results of the study showed that the behavior of substances in the atmospheric air is determined by a set of parameters, namely, the mutual location of the pollution source and the control station in the residential area; atmospheric air temperature
