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.
