Fluoride map

Probability of geogenic fluoride in groundwater exceeding the WHO guideline of 1.5 mg/l. This map is adapted from a global fluoride prediction map (Amini et al., 2008), which was developed using a rule-based statistical model. Although moderate amounts of fluoride can benefit dental health, excessive amounts can cause dental and skeletal ailments. This map is not a replacement for the independent assessment and monitoring of fluoride in groundwater sources Source: BGR, BGS, BRGM, EAWAG & UNESCO
