Light-dominated selection shaping filamentous cyanobacterial assemblages drives odor problem in a drinking water reservoir

open access: yesnpj Clean Water, 2022
Filamentous cyanobacteria have substantial niche overlap, and the causal mechanism behind their succession remains unclear. This has practical significance since several filamentous genera are the main producers of the musty odorant 2-methylisoborneol ...

Enhancement of micropollutant biotransformation by adding manganese sand in constructed wetlands

open access: yesHeliyon, 2023
Recent investigations have shown that the addition of manganese (Mn) sand to constructed wetlands (i.e., Mn-amended CWs) can improve the performance of organic micropollutants (MPs) removal. In addition to the direct oxidation and adsorption of Mn oxides,

A Model Study on the Role of Wetland Zones in Lake Eutrophication and Restoration

open access: yesThe Scientific World Journal, 2001
Shallow lakes respond in different ways to changes in nutrient loading (nitrogen, phosphorus). These lakes may be in two different states: turbid, dominated by phytoplankton, and clear, dominated by submerged macrophytes. Both states are self-stabilizing;
