In order to understand characteristics of atmospheric heavy metal deposition in Daqing City, 17 samples collected from 17 representative sites were taken using bulk deposition samplers during the period of 2008-2009 (about 365 days). The samples were analyzed for heavy metal concentration by atomic fluorescence spectrometry (AFS) and Inductively Coupled Plasma-Atomic Spectrometry (ICP-AES). The results showed that atmospheric deposition of ω (As), ω (Hg), ω (F), ω (Cd), ω (Cr), ω (Ni), ω (Cu), ω (Pb), ω (Zn) were obviously higher than that of surface soil (0-20cm), which also has strong correlation (0.9656) between the two carriers. Atmospheric depositions of Cr, Cu, Mn, Ni, Pb, Ti, Zn, As, Hg, Cd which had differences in the space distribute were 17.85, 17.52, 181.51, 9.69, 15.71, 960.29, 78.81, 3.00, 0.03, 0.17 mg/m2·a, respectively, which were higher than that in North America and Europe. It is found atmospheric deposition may cause potential long-term concern on heavy metal enrichment in the surface soil.
