Some coal is high in fluorine and also has iron pyrite. The combination is deadly – when burned it make hydrofluoric acid. Coal pollution is getting deep into food and water in China where it cannot be washed away. It is damaging teeth and bones of many people. Excess fluorine consumption can often cause dental fluorinosis, a condition in which excess fluorine is deposited in the teeth, discoloring them. In more severe cases, fluorine deposition in the bones can lead to osteofluorosis, which can cause disfigurement, deformity, and chronic pain.
