Comparative Study of Geo-Accumulation Index and Enrichment Factor in Source Apportionment of Atmospheric Particulate Matter

Geo-accumulation Index and Enrichment Factor were applied in source apportionment of Changchun atmospheric particulate matter. By mutual comparison with the results respectively, explored the similarities and differences. The result shows that the Geo-accumulation index and Enrichment Factors likes Zn, Cd are more serious, meanwhile the urban dust, soil wind dust, coal dust are the mainly pollution sources of Changchun air pollution, both methods can make a scientific evaluation to the human impact of Changchun particulate pollution in the atmosphere, provide an important reference for atmospheric particulate matter source apportionment.
