This is an initiative by METAMETA, for creating mass awareness and create access to resources related to the fluorosis. Fluorosis impacts are found extensively covering many parts of the world. The ill health, disabilities and sometimes death is caused by fluorosis to the life on earth. Pure water is scarce and is not easily available to all. Deprived sections of the society consume contaminated water and take ill periodically, often resulting in epidemics. The water may be contaminated by natural sources or by industrial effluents. One such contaminant is fluoride. Fluoride is a salt of the element fluorine. Fluorine is the most highly reactive element of halogen family. Small amounts of it are found in seawater, bone, teeth and in ground water mainly as fluoride ion. Most fluoride associated with monovalent cations such as NaF and KF is water soluble, while the one formed with divalent cations such as CaF2 and PbF2 is generally insoluble.

Fluoride is “more toxic than lead and less toxic than arsenic” and is an accumulative toxin. Fluoride has dual significance; if its content is less then it may result in problems like dental caries. World Health Organisation (WHO) recommends it in the range of 0.1– 0.5 ppm. The standard of the United States is between 0.6 and 0.9 ppm, and of India 1 and 15 ppm. Thus the requirement of fluoride content varies among countries and depends on the geography and the age of people involved.
