摘　　要：为研究石家庄市大气颗粒物的污染特征及其来源,于2013年2月采集TSP,PM10和PM2.5样品,并对其质量浓度、无机元素、水溶性离子和碳组分进行分析.结果显示：采样期间TSP,PM10和PM2.5日均质量浓度分别为249～696,157～571和133～488 μg/m3,颗粒物污染严重,各化学组分在细粒子中的富集更为明显.Cu,Cd,Pb,Co,Ni,Zn,V等元素受人为污染严重,TSP,PM10,PM2.5中水溶性离子平均质量浓度为158.82,147.31,127.84μg/m3,碳组分质量浓度均值分别为53.53,49.05和38.62 μg/m3,污染水平较高,存在二次污染.To study pollution characteristics and sources of atmospheric particulate matter in Shijiazhuang City, TSP, PM10, PM2.5 particulate matter samples and source categories samples were collected in February 2013. The mass concentration, inor- ganic elements, water-soluble ions and the carbon component were determined. The results show that TSP, PM10 and PM2.5 daily average concentrations are 249~696, 157~571 and 133~488μg/m3 respectively, the air is heavily polluted by particu- late matter, and chemical components in fine particle concentration are more obvious. Cu, Cd, Pb, Co, Ni, Zn and V elements subjected to anthropogenic pollution are serious. In TSP, PM10 and PM2.5, water soluble ion average concentration are 158.82, 147.31 and 127.84 μg/m3 respectively, the carbon component average concentration is 53.53, 49.05 and 38.62μg/m3 respec- tively, the pollution level is high, and there are secondary pollution.
