http://www.fluoridealert.org/professionals.statement.html has a lot of information.
This link has information on the harm fluoride is doing. http://www.fluorideaction.org/statement.august.2007.html
1. The publication in 2006 of a 500-page review of fluoride’s toxicology by a distinguished panel appointed by the National Research Council of the National Academies (NRC, 2006). The NRC report concluded that the US Environmental Protection Agency’s (EPA) safe drinking water standard for fluoride (i.e. maximum contaminant level goal or MCLG) of 4 parts per million (ppm) is unsafe and should be lowered. Despite over 60 years of fluoridation, the report listed many basic research questions that have not been addressed. Still, the panel reviewed a large body of literature in which fluoride has a statistically significant association with a wide range of adverse effects. These include an increased risk of bone fractures, decreased thyroid function, lowered IQ, arthritic-like conditions, dental fluorosis and, possibly, osteosarcoma.
1. The average fluoride daily intakes (*) associated with many of these adverse effects are reached by some people consuming water at the concentration levels now used for fluoridation — especially small children, above average water drinkers, diabetics, people with poor kidney function and other vulnerable sub-groups.
2. The evidence provided by the US Centers for Disease Control and Prevention (CDC) in 2005 that 32% of American children have dental fluorosis – an abnormal discoloration and mottling of the enamel. This irreversible and sometimes disfiguring condition is caused by fluoride.
3. The American Dental Association’s policy change, in November 2006, recommending that only the following types of water be used for preparing infant formula during the first 12 months of life: “purified, distilled, deionized, demineralized, or produced through reverse osmosis.”
4. The CDC’s concession, in 1999 and 2001, that the predominant benefit of fluoride in reducing tooth decay is TOPICAL and not SYSTEMIC. (meaning when applied to the outside of the tooth and not from within the body)
5. In 2000, the publication of the UK government sponsored “York Review,” the first systematic scientific review of fluoridation, found that NONE of the studies purporting to demonstrate the effectiveness of fluoridation to reduce tooth decay were of grade A status, i.e. “high quality, bias unlikely”
6. The publication in May 2006 of a peer-reviewed, case-controlled study from Harvard University which found a 5-7 fold increase in osteosarcoma (a frequently fatal bone cancer) in young men associated with exposure to fluoridated water during their 6th, 7th and 8th years (Bassin et al., 2006).
7. The admission by federal agencies, in response to questions from a Congressional subcommittee in 1999-2000, that the industrial grade waste products used to fluoridate over 90% of America’s drinking water supplies (fluorosilicate compounds) have never been subjected to toxicological testing or FDA safety-tested approved for human ingestion
8. The publication in 2004 of “The Fluoride Deception” by Christopher Bryson. This meticulously researched book showed that industrial interests, concerned about liabilities from fluoride pollution and health effects on workers, played a significant role in the early promotion of fluoridation.
One of the so called studies you cited states that fl- leads to a lower IQ. So now we know your problem is you have a lower IQ from fl-.
