Abstract
This paper analyses the atmospheric dust in Linyi City about the content and the form distribution of heavy metals. The main research focuses on the eight kinds of heavy metal elements, including As, Cd, Cr, Cu, Hg, Mn, Pb, Zn. The research results show that the annual atmospheric dust deposition in the heavy industrial zone reaches the highest amount at 88.50 g/m2. In the Park district, the figure of the year is 28.27 g/m2; compared with the soil background values, the heavy metal content, Hg, Cr, Pb, As, Cd, increased obviously. In addition, the content of Zn is beyond the soil background values of 18 times. And in the industrial zone the content of Zn has the top amount of 3545.55 mg/kg. The enrichment factor of Cu, Cd element is 50~70. The atmospheric dust deposition of Mn is similar to soil background value. Moreover, the source of Mn is mainly from the natural particulate matter of soil.
