Separately, the EPA has a longstanding requirement that water systems cannot have more than 4 milligrams of fluoride per liter of water. That standard is designed to prevent skeletal fluorosis, a potentially crippling disorder which causes weaker bones, stiffness and pain. B...

Fluorine, from which fluoride is derived, is the 13th most common element in the earth. It is released into the environment naturally in both water and air. Fluoride compounds are released into the environment through the weathering of rocks and through atmospheric emissions from volcanoes and seaw...
As groundwater quality is not regularly tested in many areas, it is often unknown if the water in a given well or spring contains harmful levels of fluoride. Here we present a state-of-the-art global fluoride hazard map based on machine learning and over 400,000 fluoride measurements (10%...
Likewise, there is a need to map situations including populations, settings and methods as they are strongly associated with intake. Previous reviews in this area have focused on synthesising the evidence on the use of 24 h urine as a biomarker for monitoring fluoride exposure [8] or explored...
Not onlyfluoride, but geologically enriched arsenic, also is a significant problem in India'sgroundwater. The researchers working with Podgorski are therefore planning to compile a hazard map for this substance as well. "A hazard map doesn't help anyone, of course, but it provides the authoriti...

Analysis of spatial variation of groundwater fluoride concentration through the use of GIS technology software platforms like Arc View 3.2a and Maplnfo Professional 8.5 has enabled the identification of low-fluoride and high-fluoride areas within the watershed. Geochemical data indicates that 38% of ...
