Eutrophication state monitoring for unhealthy aquatic ecosystem via free-floating macrophytes pattern and behavioral
Nutrient enrichment or eutrophication is a process of increasing plant nutrients in water bodies, frequently due to run-off from the land, which causes a dense growth of plant life.

| Summary: | Nutrient enrichment or eutrophication is a process of increasing plant nutrients in water bodies,
frequently due to run-off from the land, which causes a dense growth of plant life. Eutrophication
process is assisted by internal and external sources of nutrients such as nitrogen fixation and
phosphate. In freshwater ecosystem, anthropogenic source of nutrients such as detergents,
fertilizers and organic debris are among the sources of excess nutrients for nitrogen and
phosphorus. It also has been proved to be a major factor which contributes to eutrophication and
consequent algal blooms, spreading of certain aquatic macrophytes, depletion of oxygen and loss
of key species leading to degradation of many freshwater ecosystems. This study aimed to
discover the abilities of free-floating aquatic macrophyte species as an phytoindicator for
eutrophication either at contamination or pollution level in polluted aquatic ecosystem to support
their upcoming development and prospective through landscape ecology approach. The effects of
nutrients (ammonium, phosphate, nitrate and nitrite), the free-floating aquatic macrophytes and
locations have been studied on eutrophication in aquatic freshwater ecosystem. All species (
Eichhorniacrassipes, Lemna minor, Neptuniaoleracea, Spirodellapolyrhiza, Salviniamolestaand
Pistiastratiotes) were detected with high level of phosphate at level III at all localities (Pahang,
Selangor and Kelantan). Ammonium concentration was varied from class I to class III. In
conclusion, changing in E.crassipes, L.minorand S.polyrhiza pattern and behavioral are proven to
be the best phytoindicator for eutrophication state monitoring. |
