The distribution and source of atmospheric dustfall in the southern plain of Hebei Province

Abstract：From November 2007 to November 2008, the authors collected 48 samples of atmospheric dustfal in the southern plain of Hebei Province. All dustfall samples were analyzed for concentrations of Al, K, Ca, Cr, Cd, Pb, Se, Mo, I, F and S. The calculation of related coefficients and enrichment factors indicates that the primary source of the atmospheric dustfall is soil in the southern farmland, and some elements may be polluted by coal burning. The calculation of annual fluxes of elements show that the atmosphere quality of southern plain is obviously lower than that of the plain area of Beijing. The multi-elements annual fluxes are maximum in Changzhou City, and minimum in Handan City. The elements assemblage in Shijiazhuang City is characterized by Cd, Hg, Mo and Se, with the elements annual fluxes being maximum.
