Assessment of exposure, intake and toxicity of fluoride from groundwater sources in Unnao district of Uttar Pradeshposted 8 years 11 months ago
Fluoride is one of the most commonly found elements in the earth’s crust. It is naturally found d in water and helps in healthy tooth development and cavity prevention. However its high concentration in water can be harmful to human health. The amount of Fluoride (F) occurring naturally in groundwater is governed principally by climate, composition of the host rock, and hydrogeology. As per the World Health Organization and Indian Council of Medical Research the permissible limit to fluoride in drinking water is 1.5mg/L. Anything more than this value can cause fluorosis (dental and skeletal), which can affect the bones and teeth. In the backdrop of this aspect of water quality, this paper in RASĀYAN Journal of Chemistry, tries to assess the exposure to fluoride through drinking water consumption and to elucidate fluoride endemic areas through mapping in Unnao district of Uttar Pradesh.
