保定市区夏季环境空气污染状况分析

Analysis for Summer Ambient Air Pollution in Baoding

利用保定市2013年7月、8月份6个环境空气自动监测子站大气环境监测统计数据,对保定市区夏季环境空气质量状况进行分析,探讨了PM2.5、NOx、SO2、和CO 4项大气污染物的日变化规律。结果表明:二氧化硫的日变化呈单峰型结构,PM2.5的日变化表现为夜间高白天低,氮氧化物及一氧化碳的日变化呈现双峰型特征的变化规律。

The air quality status was analyzed by utilizing the statistical data in Baoding during July and August in 2013 collected by 6 automatic atmospheric environmental monitoring stations. The diurnal variation of PM2. 5,NOx,SO2,and CO four atmospheric pollutants was discussed. The results showed that the diurnal variation of sulfur dioxide exhibits a single peak structure; the diurnal variation of PM2. 5exhibits high during daytime and low during nighttime; nitrogen oxides and carbon monoxide diurnal variations exhibit bimodal variation characteristics.
