eutrofisoitumisessa

Eutrofoitumisessa refers to the process of eutrophication, which is the excessive richness of nutrients in a lake or other body of water. This commonly occurs due to the runoff of man-made substances, particularly phosphates and nitrates, from agricultural and urban areas. While eutrophication is a natural process, human activities have significantly accelerated its rate and intensity.

The increased nutrient levels fuel an overgrowth of algae and aquatic plants, leading to algal blooms. When these organisms die and decompose, they consume large amounts of dissolved oxygen in the water. This depletion of oxygen, known as hypoxia or anoxia, can create dead zones where fish and other aquatic life cannot survive.

Consequences of eutrophication include loss of biodiversity, degradation of water quality, and impacts on recreational activities like fishing and swimming. Treatment strategies often involve reducing nutrient inputs from point sources like sewage treatment plants and non-point sources such as agricultural fertilizers and storm water runoff.
