【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。更多还原

【Abstract】 To study the atmospheric particulate matter and pollution sources of Shijiazhuang City,TSP,PM10 and PM2. 5were 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. 5had good statistical correlation and homology.更多还原
