Study on Characteristics of Concentration Changes of Major Air Pollutants under Different Meteorological Factors
The concentration of air pollutants is influenced by various factors,such as meteorological conditions,terrain,and distri-bution of emission sources.If the concentration is too high,it will cause damage to the ecological environment.Therefore,in order to avoid further deterioration of the air,a study on the characteristics of changes in the concentration of major air pollutants under different meteorological factors is proposed.The concentration of six air pollutants of SO2,NO2,CO,O3,PM2.5,and PM10,were used to analyze the concentration and air quality index at different time scales.The variation pattern of AQI and the impact of different meteorological fac-tors on the concentration of six main air pollutants were studied.According to the analysis results,it can be seen that the concentration of major air pollutants in Linyi City is significantly correlated with meteorological factors,and there is a certain regularity in the variation characteristics.This characteristic can be used to improve the air quality in Linyi City.
