Eutrophication and pollution
water pollutionOriginally uploaded by satel444
Eutrophication is the result of nutrient pollution. When a certain land, or lake, or sea receives excessive amounts of nutriens(mostly phosphorus or nitrogen) the result is eutrophication. Aquatic environments polluted with fertilizers is an example. Increased chemical nutrients means productivity. However this productivity is very dangerous for the ecosystem’s “health”. The most common result of eutrophism is the algal bloom.
Here are some ecological effects of eutrophism by wikipedia
Increased biomass of phytoplankton
Toxic or inedible phytoplankton species
Increases in blooms of gelatinous zooplankton
Decreased biomass of benthic and epiphytic algae
Changes in macrophyte species composition and biomass
Decreases in water transparency (increased turbidity)
Color, smell, and water treatment problems
Dissolved oxygen depletion
