2015年辽宁省主要大气污染物时间分布特征分析

根据辽宁省环境空气质量监测数据,对2015年辽宁省6项主要大气污染物的时间分布特征进行了分析,结果表明,PM2.5,PM10,SO2,NO2,CO浓度均为冬季高于夏季、采暖期高于非采暖期,O3-8 h浓度则相反。

According to the monitoring data of environmental air quality in Liaoning Province, the time distribution characteristics of six major pollutants （PM2.5,PM10,SO2,NO2,CO and O3-Sh） in 2015 were analyzed. The results showed that the concentrations of PME2.5,PM10,SO2,NO2 and CO were higher in winter than in summer and that of the heating period was higher than that of non-heating period, while the O3-8h concentrations were the opposite.
