  • eutrophication

    Hypertrophication; process by which addition of artificial or natural substances, such as nitrates and phosphates, to a body of water increases the concentration of dissolved nutrients, this in turn stimulating the growth of aquatic plant life, especially phytoplankton, and typically resulting in depletion of dissolved oxygen. Negative effects include reductions in populations of fishes and other organisms incapable of withstanding this hypoxia.
