青岛大气颗粒物的扫描电镜研究和污染源识别

Scanning Electron Microscopyic Study of Qingdao Aerosol and Pollution Source Identification

应用扫描电镜－Ｘ射线能谱对青岛市大气颗粒物定性分析。单个颗粒物分析和多个颗粒物复合分析的结果，为污染源识别和相对重要性的估计提供了重要信息：青岛市大气颗粒物的来源，主要有土壤扬尘和燃煤飞灰、硫酸钙和其他硫酸盐类的二次颗粒物、有机物质颗粒物、天然海盐、工业钡盐与其他类型的工业排放。

Qualitative analyses of Qingdao aerosol samples have been performed by using scan- ning Electron Microscopy-X-ray Energy Dispersive Analysis(SEM-DEDX)technique,Indi- vidual particle analysis as well as composite analysis of many particles provide substantial informa- tion form the source identification and contribution estimate respectively. The sources of Qingdao aerosol include:soil dust and coal fly ash,secondary particles as a variety of sulfate,carbona ceous particles,sea salt,barium salt and other kinds of industrial emission.
