The individual particle analysis with SEM/EDX showing the morphology and chemical composition were conducted on 1600 individual particles within 16 aerosol samples collected in Wuda-Wusitai Industrial Park, Inner Mongolia, during the summer of 2015. The results suggest that the major particle types included mineral particles, combustion-originated particles, and sulfur-containing particles. Specifically, the mineral particles included common aluminosilicates and carbonates as well as weathered coal gangue and dust particles, while the combustion-originated particles contained not only the usual fly ash, soot aggregates and floccule carbon particles, but also the raw coal dust. Statistically the soot aggregates, aluminosilicates and dust particles accounted for 64% of total particles. The weathered coal gangue and raw coal dust were mainly presented as inhalable particles (2.5~10μm), while soot aggregates and dust particles were mainly ultrafine particles (<1.0μm). In all, the individual particle analysis suggested that the main sources of atmospheric particulates in the typical coal industrial park were coal combustion and traffic inside the park, as well as the upwind coal production and the natural desert influences.
