Abstract

This paper presents distribution of PHOSPHORUS (P) (total P, organic and inorganic P) and parameters related to their releasing to the water column in the southern of the CASPIAN SEA. 36 samples of SURFACE SEDIMENTS (with triplicate) were collected from four sampling stations namely Anzali, Tonekabon, Noshahr and Amirabad at depths of 5, 10, 20 m during summer 2013. Several forms of the PHOSPHORUS in sediment were separated and extracted according to sequential extraction method. In the other hand, the concentration of Al, Fe and Ca and some parameters like Eh, EC and pH were measured for finding their relation with PHOSPHORUS releasing. Results showed that the most abundant forms of PHOSPHORUS were Ca-P (96.02%) and loosely-P(0.19%) has the lowest amount. Inabundances of different forms of PHOSPHORUS follow the order: Ca-P>Org-P>Fe-P>Al-P>Loosely-P. In conclusion, the high amount of pH in sediment and anaerobic condition (Eh<0) release the Fe bound P (2.7%) and loosely bound P to water column.
