In order to understand the characteristics of atmospheric heavy metal deposition in Harbin City, 46 deposition samples were collected which 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 deposition flux was calculated. Sources analysis was made by the method of principal component analysis (PCA), Pearsons and enrichment factor (EF). The following points can be gained through multivariate analysis. Mn and Co are mostly from natural sources while the others may be brought by coal dust, vehicle emissions and metal smelting.
为了解哈尔滨市大气重金属沉降特征，于2008 - 2009年期间（约365天）使用大容量沉降采样器采集了46个沉降样品。采用原子荧光光谱法（AFS）和电感耦合等离子体原子光谱法（ICP - AES）对样品中的重金属浓度进行分析，并计算沉降通量。通过主成分分析（PCA）、皮尔逊相关分析和富集因子（EF）法进行源解析。通过多变量分析可得出以下几点：锰和钴主要来自自然源，而其他元素可能由煤尘、汽车尾气排放和金属冶炼带来。
