Update Suggestions Water Fluoridation
editI see you have edit authority. I put the following in TALK, but thought I'd send directly to you as the beginning of the article has garbled misrepresentations of fact and nomenclature:
May I suggest:
In 2011, the World Health Organization suggested a water concentration of fluoride no higher than 1.5 ppm (parts per million) to protect population health. In 2024, a systematic review by the Department of Health and Human Services' National Toxicology Program found that individual doses at or above 1.5 mg/L are associated with lower IQ in children, a dose-response trend with no discernible threshold below 1.5 mg/L. The ppm concentration is the equivalent mg/L dose assuming that fluoride in water is the only source of fluoride exposure and that the individual only consumes one liter of that water per day, i.e. 1.5 concentration equals 1.5 dose. However, many consumers consume over two liters of water per day as well as consume foods and pharmaceuticals containing fluoride. Hence, the emphasis on individual dose rather than water concentration.
In September 2024, a U.S. federal court ruling found that "fluoridation of water at 0.7 milligrams per liter (“mg/L”) – the level presently considered “optimal” in the United States – poses an unreasonable risk of reduced IQ in children." Judge Edward Chen further pointed out that EPA's own processes require a 10x "uncertainty factor," aka safety factor, between a hazard and exposure, that the hazard determination has been met by the examination of facts at trial and that the EPA must take action to eliminate that risk per the Toxic Substances Control Act. The current EPA maximum contaminant level (MCL) which requires remedial action is 4 ppm.
An October 2024 Cochrane Systematic Review found that the reduction in cavities in fluoridated communities is waning, i.e. only a fraction of a single cavity in baby teeth which "may not be real" because of the low quality of the efficacy studies. Dental fluorosis, the evidence of fluoride toxicity during early childhood that stains and sometimes pits teeth, is well-documented as increasing. Bottled water typically has unknown fluoride levels in the U.S. Canada, which has a MCL of 1.5 ppm, labels fluoride content on bottled water.
