| Abstract: | atmospheric dust samples were collected at Lanzhou University and factor analysis was used to identify the sources. The results showed that there were four sources as the major contributors. About 41^04% of the dust came from coal combustion and 22^97% from wind-blown sand and soil, while motor vehicle emission and building materials accounted for 18^67% and 12^84% respectively, and 4^48% of the dust was from other sources. |
