Air quality and forecast in Changji City from 2018 to 2022
Objective To analyze the air quality in Changji City from 2018 to 2022,and provide important data support and decision-making basis for environmental protection,public health,urban planning and international cooperation.Methods The data of atmospheric pollutants in Changji City from 2018 to 2022 were collected,the atmospheric environment in the region was analyzed,and the seasonal differential auto-regressive integrated moving average model was used to predict the concentration trend of major atmospheric pollutants in 2023.Results PM10 and PM2.5 were the main air pollutants in Changji City from 2018 to 2022,and the pollution of other pollutants was not obvious.The six conventional pollutants had seasonality,with PM10,PM2.5,SO2,NO2,and CO concentrations reaching their highest in winter,while O3 had the opposite trend,with the highest concentration in summer.The air quality index(AQI)had the highest value in 2022 and the lowest value in 2018,and predicted data showed that PM10 and PM2.5 concentrations would continue to decrease in 2023.Conclusions The air quality in Changji City is gradually improving.The predicted data shows that,compared to 2022,the concentrations of PM10 and PM2.5 in Changji City will decrease in 2023.However,the pollution situation is more pronounced in winter and continuous prevention and control measures need to be taken.
