Biogeochemical processes of phosphorus and silicon in southern Bohai Sea surface sediments

Based on the author's previously obtained results on P and Si forms in southern Bohai Sea surface sediments, this study mainly foucusing on the controlling factors, existence forms, and biogeochemical processes of P and Si showed that the transferable forms of phosphorus in sediments were mainly controlled by the mineralization of organic matters and the reduction of high-valence iron; whereas the transferable forms of silicon were possibly controlled by the dissolution and precipitation as well as biochemical processes of living organisms.
