| 摘 要： | 根据2009年夏季成都市区大气中O3的监测结果,对大气中O3的浓度、分布进行了分析,并与2001年夏季成都市区的监测结果比较,分析臭氧污染水平的变化。结合同期NO2、VOCs监测结果,研究O3与两种前体物之间的相互关系。结果表明,近年来成都市区O3浓度呈上升趋势;O3浓度与NO2浓度变化趋势相反,表现为消耗NO2型光化学污染。

| Abstract: | In this paper,based on the data monitored in the summer of 2009,the concentration and distribution of ozone in urban of Chengdu was analyzed,which was also compared with that in the summer of 2001 to show the change of the ozone pollution level.With the monitoring data of NO2 and VOCs in the same period,the relationship between O3 and the two precursors were studied as well.The result showed that the concentration of O3 tended to rise in urban Chengdu in recent years,and there was a significant negative correlation between the concentration of O3 and that of NO2 which means the photochemical pollution in Chengdu was the pattern of NO2 consumption. |
