Phosphorus inactivation by aluminum in the water column and sediments: Lowering of in-lake phosphorus availability in an acidified watershed-lake ecosystem.

Original language description

Atmospheric acidification of a watershed-lake ecosystem may provide the natural conditions for in-lake P inactivation similar to the lake restoration techniques based on the artificial addition of Al salt to the water column. Atmospheric deposition of strong acids has resulted in acidification and nitrogen-saturation of soils in the Plešné Lake watershed and, consequently, in high terrestrial losses of Al, sulphate, and nitrate to the lake. Biological removal of nitrate and sulphate contributes to the total in-lake alkalinity generation and to the increase in water pH. Under higher pH, ionic Al species hydrolyze and form colloidal Al hydroxides (Alpart), which adsorb orthophosphate (o-P) in the water column. The Al hydroxides settle and increase the Psorption capacity of the sediment. The elevated content of fresh Alpart in the surface sediment reduces P release to the water column after o-P liberation from ferric oxyhydroxides during anoxia, because Alpart complexes are not sensitive
