To study the atmospheric particulate matter and pollution sources of Shijiazhuang City, TSP, PM10 and PM2�5 were collected in 2013 from April to May in six districts of the main city, and 22 elements of the samples were analyzed by ICP-MS. The results show that Ca, Fe elements had a high content of each particle, S, K had high concentration in the PM2�5 , and Mg, Al had high concentration in PM10 and TSP. The main sources of particulate were coal dust, road dust and construction dust. TSP, PM10 and PM2�5 had good statistical correlation and homology.%为研究石家庄市大气颗粒物的污染特征及其来源，于2013年4-5月在主城6区分别采集TSP、PM10和PM2�5颗粒物样品，利用ICP-MS分析其中的22种元素浓度。结果表明，石家庄市城区Ca、Fe元素在各粒径颗粒物中含量都较高，PM2�5中的S、K含量较高，PM10和TSP中Mg、Al的浓度相对较高。颗粒物的主要来源为燃煤尘、道路尘和建筑尘， TSP、PM10和PM2�5具有较好的统计相关性和同源性。
