Analysis of Changes in Air Quality Pollution Characteristics during the Spring Festival in Anyang City
In order to understand the impact of fireworks and firecrackers on air quality during the Spring Festival in Anyang City,a comprehensive analysis was conducted based on air station data and aerosol LiDAR data for three consecutive years from 2020 to 2022 on New Year's Eve.The results showed that the characterization of various parameters on New Year's Eve from 2020 to 2021 was caused by the emissions of fireworks and firecrackers.The various parameter factors of the air station on New Year's Eve in 2022 were not affected by fireworks and firecrackers.The aerosol LiDAR data shows that from 2020 to early 2021,the transmission was affected by external transmission,with transmission heights within 800 meters.According to the analysis of air station data,the transmission source was analyzed to be caused by fireworks and firecrackers.The transmission source for the first period of early 2020 is from a northerly direction,while the transmission source for the first period of early 2021 is from a southeastern direction,in 2022,the main airflow will be towards the northwest and will not be significantly affected by external transmission.Based on various types of data,it is evident that the implementation and effectiveness of the three consecutive years of fuel and gas ban measures from 2020 to 2022 have been significant.
