About this Research Topic
Eutrophication is a primary water quality issue for freshwaters of the world. Phosphorus (P) is an essential nutrient and is also one of the key elements limiting primary productivity in lake ecosystems, and a determinant of eutrophication of many lakes. The predominant inorganic forms of P are the most bioavailable forms of P, and emphasis has been placed on the study of inorganic P abundance, dynamics for many decades. However, in lake environments, organic P in the form of phytate, nucleic acids, phospholipids, sugar phosphates, and organic condensed P species are at least as abundant as is inorganic P. Importantly, organic P is likely an important bioavailable P source for algal blooms in some lakes.
The bioavailability and preservation of organic P in lakes, and their relationships with algal blooms are still unclear. The bioavailability of organic P in lakes and their cycling are likely important mechanisms to self-regulate P status in lakes and maintain their eutrophic status. Instead, preservation of P in sediments is an important way to reduce active P levels in lakes. Analytical methods such as 31P-NMR, enzymatic hydrolysis, HPLC-ESI-MS/MS have been applied more frequently to investigate the chemical structure, bioavailability, and geochemical cycling of organic P in lakes, such as in sediments, water, and aquatic plants. Organic P in lakes has received much more attention with the development and application of multiple analytic methods in recent years.
This Research Topic is intended to provide cutting-edge knowledge about organic P in lakes. Themes of interest include, but are not limited to the following:
1. The chemical structure and bioavailability of organic P in sediments, water, particulate P of water, aquatic plants, algae.
2. Biogeochemical cycling of organic P and its relationship with algal blooms.
3. Control of organic P cycling and of eutrophication of lakes by adsorption of various materials such as Al(OH)3
Original Research, Reviews, and Mini Reviews are welcome. Please see the Specialty Section homepages for a full list of available article types.
