Source Apportionment on Urban Raised Dust in Lucheng City

The inhalable particulate matter (PM₁₀) samples in environmental air was collected in 2008 during heating period and non-heating period at four sampling sites in the urban of Lucheng ciy. Applying ´nested chemical mass balance´ and related environmental air particulate data in Lucheng city, the author successfully analyzed the contributions and ratios of individual sources to urban raised dust, the contributions and ratios of individual sources and urban raised dust to the environmental air inhalable particulate matter (PM₁₀) as well. Urban raised dust, coal combustion dust and cement dust were the main source types of inhalable particulate matter (PM₁₀) in the city according to the results of double source apportion receptor modle, and the contributions to PM₁₀ in the heating period were 16%, 14%, 33%, respectively, while in the non-heating period were 22%, 28%, 21%, respectively.
