The global status of fluoride pollution is conceptually presented in this book. Most of the recent scientific studies undertaken the world over are carefully summarized and tabulated so as to generate a global database on the status of fluoride pollution. Further, the health issues and associated human stress effects are scientifically discussed. The conventional approaches used for defluoridation in the fluoride endemic areas are discussed in detail, highlighting their limitations. A comparative evaluation of the technologies used for defluoridation has been presented as well.
