摘　　要：使用8通道采样器ACCU(Automatic Cartridge Collection Unit)对上海吴淞地区进行大气颗粒物PM10的采样。对滤膜采用质子激发X射线荧光(PIXE)分析方法进行重金属质量浓度测定,然后对获取的数据分别进行主成分分析,讨论了吴淞地区PM10中含有的主要重金属的可能来源。PM10 samples were collected by automatic cartridge collection unit （ACCU） in Wusong District of Shanghai. Elemental concentrations of major heavy metals of PM10 were determined by proton induced X-ray emission （PIXE） technique, and results were analyzed by principal component analysis. Possible source of major heavy metals in PM10 in the District was also discussed in details.
