Abstract

With the development of industrialization and civilization, the atmospheric depositions in Haerbin city degraded in recent years. 46 deposition samples were collected to analyze their concentrations of ten elements including Mn, Zn, Pb, Cu, Cr, Ni, As, Co, Cd, Hg in 2008~2009. The samples were analyzed for heavy metal concentration by atomic fluorescence spectrometry and Inductively Coupled Plasma-Atomic Spectrometry (ICP-AES). The elements, except Mn and Co, are associated different anthropogenic sources by comparing concentrations to China soil. The deposition flux was calculated. Sources analysis was made by the method of pearsons, principal component analysis (PCA). Three sources associated by the analysis are: (1) coal combustion Cr, Mn, Zn, Hg, Cd and As; (2) road traffic emissions associated with Pb; (3) metal smelting contributing Cu. What’s more, Co is mainly from crust weathering. The paper can support the scientific research in atmospheric deposition in Haerbin city.
