How to identify by just looking at a water body that eutrophication has take place or not
Answers
Answer:
Eutrophication (from Greek eutrophos, "well-nourished"),[1] distrophication or hypertrophication, is when a body of water becomes overly enriched with minerals and nutrients which induce excessive growth of algae.[2] This process may result in oxygen depletion of the water body.[3] One example is an "algal bloom" or great increase of phytoplankton in a sandy body as a response to increased levels of nutrients. Eutrophication is often induced by the discharge of nitrate or phosphate-containing detergents, fertilizers, or sewage into an aquatic system. Lake eutrophication has become a global problem of water pollution, Chlorophyll-a, total nitrogen, total phosphorus, chemical oxygen demand and secchi depth are the main indicators to evaluate lake eutrophication level.[4]
