Cu,Zn,Cd and Pb in PM2.5  of Changchun were determined with Tesser extraction method. The  content sequence of the four elements is Zn>Pb>Cd>Cu. Elements’ distribution characteristics in acid solution, iron and manganese oxides, organic state and residue state were analysed. More specifically Cu and Zn were mainly distributed in acid solution; the majority of Cd was in acid solution  and iron and manganese oxides; but Pb was in acid solution, iron and manganese oxides and residue  in general.

摘要:

利用Tesser连续提取法测定长春市大气中PM2.5的Cu,Zn,Cd,Pb, 并分析各元素在酸溶态、 铁锰氧化物结合态、 有机态和残渣态中的分布特征. 结果表明: 4种元素的质量浓度Zn>Pb>Cd>Cu; Cu和Zn主要分布在酸溶态, Cd主要分布在酸溶态和铁锰氧化物结合态, Pb主要分布在酸溶态、 铁锰氧化物结合态和残渣态.
