1北京大气细粒子PM_(2.5)的化学组成显示文摘为了解北京大气细粒子(PM2.5)的污染水平和污染特征,在车公庄和清华园进行了连续1年、每周1次同步采样和全样品分析。2个采样点PM2.5的化学组成相似。含碳组分和水溶性离子是主要的组分,其质量浓度之和超过PM2.5的50%。有机碳、元素碳和细粒子PM2.5的季节变化一致,即冬季质量浓度最高,夏季最低。夏季NO-3的质量浓度最低且在采样过程中从特氟隆滤膜上有近50%的挥发。SO2-4不同于PM2.5的季节变化主要取决于SO2的转化率。地壳元素的质量浓度从冬季到春季大幅度上升,春季沙尘天气频是一个重要原因。杨复沫 贺克斌 马永亮 张强 姚小红 Chak K.
