EVALUATION AND ANALYSIS OF AMBIENT AIR QUALITY IN JIAOZUO CITY
Journal Title: Engineering and Technology Journal - Year 2023, Vol 8, Issue 07
Abstract
Taking Jiaozuo agglomeration area as the research area, the environmental quality evaluation was carried out. The monthly and annual variation characteristics of 6 basic pollutants and 3 supplementary monitoring pollutants were analyzed by single factor index and ambient air quality index ( AQI ). The results showed that the AQI value of the average concentration in 2019-2021 reached the secondary standard. Compared with the air quality in 2019 and 2020, the single factor pollution index decreased year by year in 2021. The annual air quality index of 2020 and 2021 shows that the average value of AQI increases from October to the highest value in January of the second year, decreases from January to the lowest value in July and August, and the three supplementary monitoring pollutants all meet the evaluation criteria. The ambient air quality pollutants in the study area are mainly PM10 and PM2.5. It is necessary to take corresponding measures to prevent air pollution and provide scientific basis for atmospheric environmental governance.
