DISTRIBUTION OF PHOSPHORUS IN SURFACE SEDIMENT FROM OFFSHORE NORTHERN JIANGSHU
苏北海域表层沉积物中磷的分布

The contents of phosphorus in the surface samples from offshore, Northern Jiangshu have been analysed, Determinations of phosphorus were made by speetrophotometrie method. The phosphorus content ranges from 0.15 to 0.33%. The concentration of phosphorus in the surface sediment is generally correlated with that in the seawater. The geological environment can be reflected by the concentration of phosphorus in the sediment. Futhermore, based OB the distribution characteristics of phosphorus, the sources of sediments can be elucidated.
