Freshwater wetland eutrophication

The traditional perception of wetlands as nutrient sinks has led them to be used as wastewater disposal areas for a long-time, resulting in a severe alteration of the structure and function by eutrophication. Nutrient loading is usually linked to hydrological alterations which encompasses shifts in...
