Fluoride At Twice the Recommended Limit Is Linked To Lower IQ In Kids (apnews.com) 153
An anonymous reader quotes a report from the Associated Press: A U.S. government report expected to stir debate concluded that fluoride in drinking water at twice the recommended limit is linked with lower IQ in children. The report, based on an analysis of previously published research, marks the first time a federal agency has determined -- "with moderate confidence" -- that there is a link between higher levels of fluoride exposure and lower IQ in kids. While the report was not designed to evaluate the health effects of fluoride in drinking water alone, it is a striking acknowledgment of a potential neurological risk from high levels of fluoride. Fluoride strengthens teeth and reduces cavities by replacing minerals lost during normal wear and tear, according to the U.S. Centers for Disease Control and Prevention. The addition of low levels of fluoride to drinking water has long been considered one of the greatest public health achievements of the last century.
The long-awaited report released Wednesday comes from the National Toxicology Program, part of the Department of Health and Human Services. It summarizes a review of studies, conducted in Canada, China, India, Iran, Pakistan, and Mexico, that concludes that drinking water containing more than 1.5 milligrams of fluoride per liter is consistently associated with lower IQs in kids. The report did not try to quantify exactly how many IQ points might be lost at different levels of fluoride exposure. But some of the studies reviewed in the report suggested IQ was 2 to 5 points lower in children who'd had higher exposures.
Since 2015, federal health officials have recommended a fluoridation level of 0.7 milligrams per liter of water, and for five decades before the recommended upper range was 1.2. The World Health Organization has set a safe limit for fluoride in drinking water of 1.5. The report said that about 0.6% of the U.S. population -- about 1.9 million people -- are on water systems with naturally occurring fluoride levels of 1.5 milligrams or higher. The 324-page report did not reach a conclusion about the risks of lower levels of fluoride, saying more study is needed. It also did not answer what high levels of fluoride might do to adults.

In a 26-page report issued earlier from the Minneapolis FBI Special Agent working the Moussaoui case, the conclusion stated that there were "numerous inconsistencies" in Moussaoui's story, that he had taken a two-month-long trip to Pakistan which ended less than three weeks before his coming to the U.S., and that he could not explain the source of $32,000 in his checking account.

Typical water treatment involves sodium fluoride (NaF); sodium fluorosilicate (Na2SiF6); and fluorosilicic acid (H2SiF6), not pure fluorine, the goal is that the substance is ingested and then the fluorine ion gets absorbed by the body. All of those are also used in eg. PET imaging
The isotope used in PET imaging, fluorine-18, is manufactured by using an accelerator to bombard 18O with protons. It is not present in natural Sodium fluoride, Sodium fluorosilicate, or any naturally occurring source that would possibly be sued as the source of fluoridating water.

False-ish. There was not an "industrial waste problem". The reality is little more than an effort of reusing waste materials from one industry in another. Adding flouride to drinking water came long LONG time after the phosphate industry had the waste product. Fluoride waste was disposed before, the fact that it could be re-used elsewhere isn't an indication that it was "solving a problem".
It is true that industrial waste is used as a fluoride source, but only because at the concentrations required it is more than suitable for use. If you instead needed to add it to toothpaste not only would the concentrations of fluoride need to increase by a factor of 500x so would the concentrations of arsenic, lead and other byproducts - hence for toothpaste it is manufactured pure, but for the water industry it is sourced from a waste product.
Your causality is backwards. The countries with the most fluoridated water are the countries with the easiest and cheapest access to fluoride - i.e. the ones who have the ample industrial waste. It was the industrial waste solving the problem of fluoride being expensive to produce.
