A review of factors affecting P release from aquatic sediments and controlling techniques
Phosphorus in water sediments plays an important role in eutrophication.Not all forms of P can be released and bioavailable.Phosphorus bound to Fe,Mn and A1 has the highest risk to be released into water,while Ca-bound phosphorus is generally released at low rates.As a sequential chemical extraction,the SMT protocol established by European Commission can provide both P forms and their bioavailability information.PhosphoruS release from sediments depends on a variety of physical,chemical and biological processes.Besides of the limitation of external inputs.many in-situ restorations have been developed.And the restorations mainly involve direct precipitation of P by metal salts,barrier insulation,in-situ stabilmarion and bioremediation by macrophytes.
