The hierarchical cluster analysis and principal component analysis methods were used to identify the pollution sources of dustfall in Tongling City, an important mining city in East China. The results showed that there were three sources as the main contributors for the dustfall in Tongling city.  The main sources are the smelting dustfall, mining dustfall and coal combustion dustfall. About 43.29% of the total concentration of pollution elements came from the smelting and mining processes, 32.23% came from the coal combustion, the contribution of blown soil and motor vehicle emission was about 10.53%, and the rest 13.94% contamination came from the other sources.
