Forms of phosphorus and silicon in the natural grain size surface sediments of the southern Bohai Sea

The forms of phosphorus and silicon in the natural grain sizes surface sediments of the southern Bohai Sea were studied. In sediments, the organic matter bound form of phosphorus was the main form of transferable phosphorus and ranged from 0.37 ,μmol/g to 1.57 μmol/g, accounting for 10.7 % of the total phosphorus, others were the carbonate bound form, iron-manganese oxide bound form and ion-exchange able form; the transferable form of phosphorus accounted for 19.2% of the total phosphorus. Silicon' s carbonate bound form was predominant over others among its transferable forms, and content ranged from t. 55 μmol/g to 8.94 μmol/g, accounting for 0.05 % of the total silicon; the total amount of transferable silicon forms accounted for only 0.12% of the total silicon. Therefore, 19.2 % of the total phosphorus and 0.12 % of the total silicon contained in the surface sediments of the southern Bohai Sea could participate in the biogeochemical cycling.
