| Abstract: | 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. |
