  • Fluoridation: 3. What are the possible health effects of fluoride, and

    It has been found in some parts of India, China and Africa where fluoride intake is exceptionally high. This is due either to fluoride in drinking water reaching unusually high levels or to burning fluoriderich coal in confined spaces. In Europe, skeletal fluorosis has only been seen in workers in mineral processing industries.
