AbstractSediment phosphorus release accelerates river eutrophication, whose key components remain unclear. In this paper, fractionation and sorption behaviors of phosphorus and content of organic matter (OM) were measured in sediments of a Chinese eutrophic river (Nanfei River) in different months. Concentrations of Chlorophyll a and total phosphorus were also determined in water column, and they were significantly and positively related with each other. Contents of iron-bound phosphorus (Fe(OOH)similar to P), calcium-bound phosphorus (CaCO3 similar to P), acid-soluble organic P (ASOP), and hot NaOH-extractable organic P (P-alk) ranged from 161.41 to 1195.81 mg kg(-1) (mean 655.23 mg kg-1), 49.34 to 1088.41 mg kg(-1) (mean 378.30 mg kg(-1) 16.13 to 167.41 mg kg(-1) (mean 86.80 mg kg(-1)), and 17.11 to 96.50 mg kg(-1) (mean 60.41 mg kg(-1)), respectively. So the Fe(OOH)similar to P and CaCO3 similar to P accounted for the larger part of sediment phosphorus pool. The results of Path Analysis showed that Fe(OOH)similar to P and P-alk had direct influences on phosphorus status in surface water, while CaCO3 similar to P and ASOP only had direct effect on SRP in interstitial water. Thus, sediment P fractions had different release pathways that were controlled by different factors, such as redox conditions, acidity, and microbial activity. Additionally, the OM gave rise not only to content of different P forms, but also to the sorption capacity, thereby determining sediment function to act as phosphorus source or sink. Moreover, the vertical distribution of P fractions and equilibrium phosphorus concentration was studied, which is of significance for remediation and management of eutrophic rivers.; Sediment phosphorus release accelerates river eutrophication, whose key components remain unclear.
