Characteristics Of Air Pollution Indicators Under Different Time Scales Of Zarut Banner Relations With Meteorological Factors

Based on the air quality monitoring data of 2018-2021 and the corresponding ground meteorological data,the characteristics of AQI of the concentration of air quality index and the air pollution index are analyzed.Air pollutants and their correlation with meteorological factors,and a brief analysis of the sources and causes of pollutants are studied,and propose targeted and reasonable suggestions for air environmental pollution control.the results show that:(1)In the past three years,the overall air quality of Zalut Banner showed an improving trend,AQI decreased year by year,good days;winter and spring poor air quality and prone to light pollution weather,good air quality in summer and autumn,AQI changes;Zalut Banner 1,February and December are serious and concentrated pollution,but month by montho,nly one day AQI exceeds 300 in three years,reaching serious pollution level;Zalut Banner primary pollutants are ozone and PM_10,and PM₁₀and ozone in summer and autumn.(2)Overall,air pollutant concentration and temperature,humidity,wind speed and precipitation are obviously related,main pollutant ozone and temperature,summer temperature,ozone pollutant concentration with significant negative correlation,PM₁₀and humidity,wind speed,rain,spring and winter dry,PM₁₀particle pollutants concentration is rising,different pollutants in different time scales,which is closely related to meteorological factors at each time scale.(3)According to the above research and analysis,the main pollutants caused in Zalut Banner in the past three years are ozone and PM₁₀,and the main factors of ozone pollution and global warming caused by the formation of greenhouse effect,high temperature weather caused by automobile exhaust emissions.PM₁₀pollutants are closely related to construction,road cleaning and excessive emissions of industrial enterprises.Through the study of major pollutants and their causes,it can provide corresponding treatment and prevention suggestions for relevant departments to formulate reasonable and effective air environment protection measures,and provide a certain theoretical basis for the improvement and improvement of air environment quality in Zarut Banner.
