苏北海域表层沉积物中磷的分布

磷是重要的营养元素之一。它的含量低于一定的数值时,海洋浮游生物的生长和繁殖就受到限制,当它的含量太高时,又能抑制生物的生长和繁殖以致中毒死亡。

DISTRIBUTION OF PHOSPHORUS IN SURFACE SEDIMENT FROM OFFSHORE NORTHERN JIANGSHU

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.
