江阴市空气中臭氧污染变化特征研究与分析

Study and Analysis on the Change Characteristics of Ozone Pollution in the Air of Jiangyin City

臭氧作为江阴市空气污染的主要污染物,研究江阴市臭氧浓度变化特征对全面掌握江阴市空气质量概况具有重要意义。通过对2019—2021年江阴市环境空气质量监测数据的收集整理和分析,得到了江阴市臭氧污染的变化情况。结果表明:从2019年开始,江阴市环境空气中的臭氧污染呈现逐步减缓的发展趋势;4—10月是全年臭氧污染问题的重点污染发生阶段;在春季与冬季末时,主要污染物是颗粒物,而不是臭氧。臭氧及其他大气污染物之间的相互作用关系,根据数据得出规律一般是呈反比。

As the primary pollutant of air pollution in Jiangyin City,it is of great significance to study the variation characteristics of the concen-tration of O3 in Jiangyin City to comprehensively grasp the general situation of air quality in Jiangyin City.The change of ozone pollution in Jian-gyin is obtained by collecting and analyzing the monitoring data of ambient air quality in Jiangyin from 2019 to 2021.The results show that since 2019,the ozone pollution in Jiangyin City has shown a trend of gradual reduction.In summer,autumn and early winter,April and October are the key pollution stages of ozone pollution throughout the year.In spring and late winter,the main pollutants are particulate matter,not ozone.The interaction between ozone and other air pollutants is analyzed in detail,and the law is generally inversely proportional according to the data.
