其他摘要：Reduced phosphorus compounds, such as phosphite (H2PO3- and HPO32-,+3), hypophosphite (H2PO2-,+1), and phosphine (PH3,-3), have long been neglected in the phosphorus geochemical cycle. Recently reduced phosphorus compounds have been detected in many environmental sites. Their role in the phosphorus cycle is becoming a hot study spot. However, their complex environmental behavior makes a headache for many researchers due to such characteristics as the specific chemical characteristics, such as the thermo dynamical instability, kinetic stability and vast water-solubility, of the reduced phosphorus compounds induce their complicated environmental behavior and fate. This paper reviewed the sources and distribution, migration and transformation, and bioavailability of reduced phosphorus compounds in aquatic water environment. Also, analytical methods of reduced phosphorus compounds in aquatic environment were systematically expatiated. The work is helpful to further study the biogeochemical mechanisms of phosphorus in eutrophic lakes, reveal the environmental behavior of reduced phosphorus, and provide scientific information for policymakers to make a better decision on eutrophication control.
