Abstract: As a source of atmospheric particulate matter supporting analytical method of source apportionment studies, scanning electron microscopy presents a qualitative and semi-quantitative basis. The scanning electron microscopy is used to do qualitative and semi-quantitative analysis of atmospheric particulate matter samples and the sample source during the heating and non-heating periods in Jilin City.These results are consistency well with those that gets from CMB 8.2 chemical mass balance receptor model for the source of analytical results. From the results, we know that the wind and soil dust sources contribute more portion to TSP in the heating period, while the soil dust and construction dust are the main sources of TSP in the non-heating period.

Key words: atmospheric particulate, electron microscopic, CMB receptor model, source apportionment
