环境空气中臭氧污染特征及相关气象要素研究

Study on Ozone Pollution Characteristics and Related Meteorological Elements in Ambient Air

以河南省某城市环境空气质量自动监测点监测数据为基础,分析了2019年1—12月河南省城市环境空气臭氧污染浓度监测结果及同期气象资料。结果表明,河南某市城市空气中臭氧污染主要是由臭氧日平均浓度最高8h造成,超过GB 3095—2012《环境空气质量标准》二级标准的频率为14.4%。臭氧污染具有明显的季节特征,导致全年污染天数增加。经过实地调查和分析,臭氧污染与风速、温度和光照等因素有着一定的关系。基于此,探究了臭氧污染防控的相关措施。

Based on the monitoring data of an urban ambient air quality automatic monitoring point in Henan Province,the monitoring results and meteorological data of urban ambient air ozone pollution concentration in Henan Province from January to December 2019 were analyzed.As a result,ozone pollution in the air of a city in Henan Province is mainly caused by the highest daily average concentration of ozone for 8 hours,and the frequency exceeding the second class standard of ambient air quality standard(GB3095-2012)is 14.4.Ozone pollution has obvious seasonal characteristics,which leads to the increase of pollution days in the whole year.Through field investigation and analysis,ozone pollution has a certain relationship with wind speed,temperature and light.Based on this,this paper explores the relevant measures of ozone pollution prevention and control.
