Paper Title:
Bioavailability of Phosphorus Fractions for Incepting of Chlorella pyrenoidosa in the Lower Reaches of the Hanjiang River in China
  Abstract

Using total phosphorus (TP) concentrations to estimate eutrophication risk is problematic for management purposes, as only some forms of P are biologically available for phytoplankton growth. This study estimated the bioavailability of P fractions of water and the floodplain sediment in the lower reaches of the Hanjiang River in China using multiple regressions. And the effects of concentrations of P fractions on algal growth were also studied. The results showed that the total soluble P (TSP) and the particulate P (PP) can well predict the growth of Chlorella pyrenoidosa in water samples. And the exchangeable P (exch-P) and the P bound to Al, Fe, and Mn oxides and hydroxides (Fe/Al–P) were adapted to predicting the growth of Chlorella pyrenoidosa in the floodplain sediment samples.
