Eutrophication literature, from metal salts (e.g. Alum), minerals, natural clays and local soils, industrial waste products, modified clays (e.g. Lanthanum modified bentonite) and others. . The phosphate sorbent is commonly applied in the surface of the water body and it sinks to the bottom of the lake reducing phosphate, such sorbents have been applied worldwide to manage eutrophication and algal bloom . Eutrophication Eutrophication (from Greek "eutrophos", "well-nourished"), or hypertrophication, is when a body of water becomes overly enriched with minerals and nutrients that induce excessive growth of plants and algae. This process may result in oxygen depletion of the water

Australian Geographer, 46(1), 91-111. doi:10.1080/00049182.2014.986786 Natural population growth Natural population increase (in contrast to total population increase) happens as people are born (in contrast to immigration) into a country, and decrease as people die (in contrast to emigrate).
