A sediment core of 549 cm is collected from the river floodplain of Yellow River in Sanmenxia Reservoir for the test of the concentrations of organochlorine pesticides(OCPs) and minerals.

Determination of thallium chemical form in sediment core from Pearl River;

Ultrasonic measurement of seafloor sediment cores;

The organochlorinne pesticides(OCPs) and the polychlorinated biphenyls(PCBs) in sediment core collected from Lake Nansihu were quantificationally analyzed by GC-ECD.

Distribution and source characteristics of carbon and nitrogen and their burial fluxes in two core sediments from western Nansha Islands sea area;

Seawater,suspended particulate matter(SPM),surface sediment and core sediment samples from Deep Bay in 2004 were collected and 15 PAH isomers concentrations and relative parameters were analyzed,while the age of core sediment was also detected by use of the()~(210)Pb dating method.

The concentrations of organochlorine pesticides in the sediment core of Quanzhou Bay were determined by GC-ECD with the internal standard method.

Species of phosphorus in core sediments from the Changjiang Estuary and its environmental significance;

The main chemical compositions of the core sediments are SiO 2,Al 2O 3,CaO and TFe 2O 3,and then K 2O,Na 2O,MgO and MnO, which are similar to those of the shelf sediments in the East China Sea,but trace elements are richer in the core sediments.
