Eutrophication
| Formula / Notation | Algae bloom: [CO₂ + H₂O + nutrients → biomass + O₂] then → O₂ depletion |
|---|---|
| Also Known As | Cultural eutrophication; nutrient enrichment; algal bloom (consequence); hypoxia; lake eutrophication; dead zones |
What is Eutrophication?
Eutrophication is the process by which a body of water becomes excessively enriched with nutrients (mainly nitrogen and phosphorus compounds), stimulating the rapid growth of algae and other aquatic plants. When the algae die and decompose, bacterial breakdown consumes oxygen, leading to hypoxia (oxygen depletion) and mass death of aquatic organisms. It is mainly caused by agricultural runoff and sewage discharge.

Eutrophic waters can produce toxic algal blooms (cyanotoxins from cyanobacteria) — avoid contact with affected water. Drinking eutrophic water or eating contaminated fish can cause illness. Toxic algal events must be reported to environmental authorities.
