The research had two goals: (1) to warn communities with a high concentration of fluoride of the danger, initiating a reduction of the fluoride levels in order to reduce incidence rates of fluorosis, and (2) to encourage communities with a low concentration of fluoride in drinking water to add fluoride in order to help prevent tooth decay. By ...
Some 53% of these water systems have fluoride concentration within recommended levels - between 0.7mg per liter and 1.2mg per liter. Just under half of them (47%) have fluoride concentration under ...
In 2015, the U.S. Public Health Service, under the Department of Health and Human Services, set the optimal level of fluoride in water at 0.7 milligrams per liter — a level that, after decades ...
The water policy of the European Union is primarily codified in three directives: Directive on Urban Waste Water Treatment (91/271/EEC) of 21 May 1991 concerning discharges of municipal and some industrial wastewaters; The Drinking Water Directive (98/83/EC) of 3 November 1998 concerning potable water quality;
