High mobilization of phosphorus in black-odor river sediments with the increase of temperature

Abstract Increased temperatures affect water quality and ecology. However, the response of geochemical cycles of phosphorus (P) in black-odor river sediments to increased temperatures is still unclear. In this study, we found that pore water soluble reactive phosphorus (SRP) concentrations in sediments significantly increased with the rising of temperature, by 28% and 87% at 25°C and 35°C, respectively, compared with concentration at 15°C (p
