Water fluoridation is the controlled addition of fluoride to a public water supply to reduce tooth decay, and is handled differently by countries across the world. [2]Water fluoridation is considered very common in the United States, Canada, Ireland, Chile and Australia where over 50% of the population drinks fluoridated water.
For countries with available data (free-market countries), about 17,000 metric tons of fluorine are produced per year by 11 companies, all G7-resident. [27] Fluorine is relatively inexpensive, costing about $5–8 per kilogram ($2–4 per pound) when sold as uranium hexafluoride or sulfur hexafluoride.
In January, researchers at the U.S. National Institutes of Health who analyzed 74 studies from 10 countries found IQs were lower in children with higher fluoride exposure. In four studies with a ...
Toothpaste is the only realistic fluoride strategy in many low-income countries, where lack of infrastructure renders water or salt fluoridation infeasible. [98] It relies on individual and family behavior, and its use is less likely among lower economic classes; [95] in low-income countries it is unaffordable for the poor. [98]
Fluorine is a chemical element; it has symbol F and atomic number 9. ... [211] but it is a suspected carcinogen and has been banned in many European countries. ...

The report estimated between 7,000 and 14,000 tonnes of CFCs are smuggled annually into developing countries. Asian countries are those with the most smuggling; as of 2007, China, India and South Korea were found to account for around 70% of global CFC production, [32] South Korea later to ban CFC production in 2010.
