What mineral plays a major role in the eutrophication of lakes?

Phosphorus is the mineral that plays a major role in the eutrophication of lakes. It often enters water bodies through runoff from agricultural land, sewage, and industrial waste, leading to excessive algal blooms. These blooms can deplete oxygen levels in the water, harming aquatic life and disrupting ecosystems. Managing phosphorus levels is crucial for preventing and mitigating eutrophication.
