| Abstract: | The variation of phosphorus(P)bioavailability in terms of water soluble P(WSP),readily desorbable P(RDP),algal available P(AAP),and NaHCO3 extracting P(Olsen-P)in the re-suspended sediments was investigated in laboratory experiments,in which the waters and sediments were taken from campus canal.The results indicate that sediment re-suspension can promote the migration of soluble reactive P(SRP)from overlying water to sediments.The contents of AAP and Olsen-P in re-suspended sediments reduced obviously,where... |
