Description:
Sediments from the Southern Caspian Sea, located in Iranian coast were examined on the basis of P-fractionation
(five forms of phosphorus) by a sequential extraction scheme. Ninety-six surface sediment samples (for each season
with triplicate) were collected from eight sampling transects in 10 and 100 m depths during summer and winter in
2010-2011. The result indicated that the most abundant forms of phosphorus were calcium bound phosphorus.
Relative abundance of other forms of phosphorus follow the order: organic-P〉Fe-P〉Al-P〉Absorbed-P. The loosely
absorbed phosphorus represented 〈1% of the sedimentary inorganic phosphorus, while the Fe/Al phosphorus
ranged 5–6%.The calcium bound phosphorus showed considerable contribution (88%) to the sedimentary
inorganic P-loads.
