Micrographs and mineral components of atmospheric fine dust in Zibo City were investigated by means of Field-SEM, EDS and XRD. It is found that mineral composition of the dust is composed of quartz, albite, gypsum, calcite, hematite, muscovite, illite and amorphous material. SEM results imply that there exist at least three kinds of environmental origins of particles in the fine dust. Porous and round particulates are related to the high temperature industrial process, strongly weathered minerals originate from crustal composition, and well-grown crystals may result from chemical reactions in the atmosphere.
