Fluoride in Drinking Water: Health Effects and Remediation by Meththika Vithanage and Prosun Bhattacharya

Fluoride at low concentration is an essential element for dental health. However groundwater in many countries has exceeding concentrations of fluoride, which poses a health threat to millions of people around the world. It has been estimated that more than 200 million people from among 25 nations are suffering from fluorosis due to the consumption of fluoride-rich drinking water.
