Chemical characterization of individual particles (PM10) from ambient air in Guiyang City, China
چکیده انگلیسی
PM10 samples were collected during 5 days in Guiyang, China in July 2003. A total of about 2300 particles was analyzed by an automated Scanning Electron Microscope with Energy-Dispersive Spectrometer (SEM-EDS). Hierarchical cluster analysis (HCA) was used to identify different particle types that occurred in the aerosol. Seventeen particle types were identified and presented in the order of decreasing number abundance as: silicomanganese slag, soil and fly ash, coal burning, silicomanganese, quartz, syngenite, S-bearing iron, calcium rich, gypsum, sphalerite, dolomite, iron, alloy, lead sulfate, zinc rich, sulfur-rich particles and aluminum manufacturing dust. The majority of the particles in the studied size range are of anthropogenic origin, especially from metallurgical industry. The study illustrates the complexity of particle pollution in air of an industrial Chinese city and the results should be useful in planning mitigation measures.
