Fluorine in drinking water [PDF]
Journal of Hygiene, 1943 The modern study of the problem of fluorosis (chronic fluorine poisoning) became possible when an Italian, Stefano Chiaie, described, as quoted by Eager (1901), an unsightly dental dystrophy, now known as ‘mottled teeth’. The efforts to trace its aetiology have been ceaselessly continued ever since, mainly by American investigators. Outstanding amongst

Enhancement of micropollutant biotransformation by adding manganese sand in constructed wetlands
Heliyon, 2023 Recent investigations have shown that the addition of manganese (Mn) sand to constructed wetlands (i.e., Mn-amended CWs) can improve the performance of organic micropollutants (MPs) removal. In addition to the direct oxidation and adsorption of Mn oxides,

A Model Study on the Role of Wetland Zones in Lake Eutrophication and Restoration
The Scientific World Journal, 2001 Shallow lakes respond in different ways to changes in nutrient loading (nitrogen, phosphorus). These lakes may be in two different states: turbid, dominated by phytoplankton, and clear, dominated by submerged macrophytes. Both states are self-stabilizing;
