摘要
为探索解决近地面臭氧污染瓶颈问题,通过梳理柴桑区的臭氧浓度数据并进行臭氧污染分析,发现气象条件、本地污染以及外来传输均不同程度地对臭氧浓度变化产生较大影响,其中5—9月份是臭氧污染相对集中的月份,臭氧质量浓度的变化为日间高、夜间低,一天中12:00—18:00臭氧质量浓度较高,并受到本地大气中臭氧前置体排放影响较大,应要加强O_(3)和PM_(2.5)协同控制,探索臭氧污染来源与成因分析,通过联防联控、预警预报、宣传引导,积极应对臭氧污染,持续改善提升环境空气质量。
In order to explore and solve the bottleneck problem of near-ground ozone pollution,by combing the ozone concentration data in Chaisang District and conducting ozone pollution analysis,it was found that meteorological conditions,local pollution and external transmission all had a greater impact on the change of ozone concentration to varying degrees.From May to September,the ozone pollution is relatively concentrated.The changes of ozone concentration are high during the day and low at night.From 12:00 to 18:00 in the day,the ozone concentration is relatively high,and it is affected by the emission of ozone precursors in the local atmosphere.It is necessary to strengthen the coordinated control of O_(3) and PM_(2.5),explore the source and cause analysis of ozone pollution,and actively respond to ozone pollution through joint prevention and control,early warning and forecasting,publicity and guidance,and continuously improve and improve ambient air quality.
