| Abstract: | From March 2009 to March 2010,17 samples of dry atmospheric dustfall were collected from the Ganan area of Heilongjiang Province.All samples were analyzed for the concentrations of Cd,Hg,Cr,Mn,Ni,Pb,As,Cu,Zn.This paper shows the calculation and analysis of deposition fluxex.And also,the sources of the various elements were identified in terms of enrichment factors and correlation analysis.The calculation of annual fluxes of elements shows that the average deposition flux of Mn is highest with an average value of 779.33 g·hm-2·a-1,while the value of 78.62 g·hm-2·a-1 of Hg is lowest.The annual fluxes of the elements are highest in Yinhe Town and on Shuanghe Farm.The enrichment factors of Cr,Mn,Ni,As,Cu are smaller than 2,indicating these elements come from natural sources.As for Cd,Pb,Zn and Hg,the enrichment factors are greater than 2,and the correlation analysis shows that the major sources of Cd,Pb,Zn and Hg are coal burning,oil and wood combustion and refuse incineration. |
