The Research of PCBs and PAHs in Sediments of Songhua River;

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.

Study on the laboratory compression test of the Tertiary argillaceous sediments in the upstream of Yellow River under super-high pressure;

To study OM enrichment mechanism and interaction of organic matter with inorganic minerals in argillaceous sediments, we employed size grading, microscope, X-ray diffraction (XRD) and gas chromatography (GC) to obtain information on OM and minerals.

The Quaternary boulder clay in the Mt.

The extractable contents of trace heavy metals Pb、Cr、Zn、Mn、Ca、Fe、Cu and Sr in sediment sampleshave been analyzed using the six step sequential extraction procedure by Forstne' means to study speciation classification oftrace heavy metals in sediment deposition from Jinan Daming Lake.
