Phosphorus and Iron Distribution in the Sediments of the Yellow River

Abstract:

Sediment was important storeroom of pollutants and acted as the"source"and the"sink"role ^[1-2]. Phosphorus not only was a important biogenic elements but also a major limiting factor of water eutrophication.Primary productivity of water bodies was effected by phosphorus migration and circulation in interact of sea-land^[3]. As we all known,crustal abundance of iron was 6.71% and ranked fourth, it was trace elements that played an important role in activities of human life, meanwhile ,growth of planktonic algae was limited by iron. Iron has a strong absorption features because of its oxide surface features .Circulation and transformation of phosphorus were effected by geochemical cycling of iron^[4-6]. Studies have shown^[7-8]that total of phosphorus and iron can be used as an important indicator what evaluated the degree of pollution. Released phosphorus of sediments was an important factor that effected nutritional status of water bodies. TP through physical,chemical,biological effected were combined with andiron and other minerals. So, determinating TP and TFe of sediment and analyzing its relevance were very important, it could further reveal the pollution status of water and analysis the pollution trends .
