Abstract： The source of heating period atmospheric dust from 2006 to 2007 in Changchun, China was researched. The ion-coupled plasma-mass spectroscopy was used to analyze the elementary composition of the atmospheric dust, and the elemental enrichment factor(EF) method was used to inquire the dust origins. The chemical mass balance (CMB) method was employed to discuss the eigenelement of different pollution sources. The results show that As, Mn, Ca, Mg, Fe, Ti, Al, Pb, Zn and Cu elements are the major elements of the atmospheric dust. Coal dust is the major source, while soil dust contributes less of atmospheric dust in the heating period in Changchun. Ca, Al, Pb and Zn, Ti and Mn, Fe are the eigenelements for construction dust, soil dust, vehicle exhaust dust, coal dust and road cumulated dust respectively. The results of different source apportionment methodologies which are EF and CMB methods are consistent. Both of them can help to discuss the source of atmospheric dust.
