Abstract
It is a hazard to human health that urban atmospheric dustfall has increased year by year. The winter atmospheric dustfall in Linyi was studied in the paper, atmospheric dustfall carrying out heavy metal was determined by ICP-AES, and the sources of metal elements in the atmospheric dustfall was analyzed by enrichment factor method. The results showed that Cd, Zn, Cu, Pb and Hg elements in the atmospheric dustfall were significantly affected by man-made factors, and that As, Cr, Mn elements in the atmospheric dustfall were mainly derived from the crust. Meanwhile the results the sources of Zn, Cu, Pb and Hg in dustfall is closely related to coal and oil combustions, but that Cd elements in dust were deeply affected by soil
