Abstract: Electronic microscopy,X-ray diffraction,infra\|red spectrometry,atomic absorption spectrometry and chemical analysis are used for a comprehensive analysis of the exterior form and the primary,secondary and small component parts of the sediment samples collected from Xiaoqing River in Jinan,Shandong Province.Then with the incorporation of BCR’s sequential extraction procedures,a comprehensive analysis and a detailed discussion are made of the molecular forms of the trace metal pollutants such as Cu,Pb,Zn,Cr and Cd in each fractions of the BCR’s fractions scheme.It is found that the concentration of the pollution metals in the siliceous crystals in the residual increases regularly with the increase of the concentration of the relevant pollution metals in the sediment.
