Weak Link on Fluoride and Cancer Is Backed

A panel of scientific experts today endorsed the findings of a Federal investigation showing that a compound widely used to fluoridate public water supplies may cause bone cancer in male rats. The panel found that the evidence inconclusively demonstrated a weak association between fluoride consumption and the bone cancer in male rats. Federally sponsored scientists […]

Congressman Proposes EPA Study on Cutting Hydrofluoric Acid Use

U.S. Rep. Mel Levine (D-Santa Monica) on Thursday announced a proposal that would require oil refineries nationwide, including four in Los Angeles County, to phase out the use of acutely hazardous hydrofluoric acid if a federal study finds a safer alternative. “Hydrofluoric acid is dangerous business, and I am deeply concerned by the deadly threat […]

Rat Study Reignites Dispute On Fluoride

Top health officials order experts to evaluate findings on cancer in test animals A long-smoldering dispute over the safety of fluoridating public water supplies has flared anew, forcing the nation’s top health officials to reevaluate the risks and benefits of using fluorides to reduce tooth decay. The latest review was triggered by a Congressionally mandated […]

Rat Study Reignites Dispute On Fluoride

A long-smoldering dispute over the safety of fluoridating public water supplies has flared anew, forcing the nation’s top health officials to reevaluate the risks and benefits of using fluorides to reduce tooth decay. The latest review was triggered by a Congressionally mandated study that recently reported evidence that high doses of fluoride may cause cancer […]

Mexico Plant’s Acid Leak was Worse than AQMD Model

When air quality officials recommended in January that hydrofluoric acid be banned from use in Los Angeles County, oil and chemical industry spokesmen attacked their report as “unrealistic,” saying it was predicated on such a large release of the chemical that no accident of that magnitude is likely to occur. However, The Times has learned […]

Caries Preventative Already Has One Rap Against It

The unexpected positive results from the National Toxicology Program’s (NTP) rodent study of fluoride carcinogenicity will make it difficult for the Environmental Protection Agency (EPA) not to classify fluoride a carcinogen, thereby terminating 40 years of public-water fluoridation in the United States. Validated pathology results officially released by the NTP showed that, among male rats, […]

Don’t Drink the Water? Brush your teeth, but the fluoride from your tap may not do much good — and may cause cancer

Remember the great fluoride debate? Back in the 1950s, every voice of authority, from the U.S. Public Health Service to the PTA, supported adding fluoride to the water supply as an effective and totally safe way to promote healthy teeth. The only opponents seemed to be John Birchers and other extremists who regarded the scheme […]

The Fluoride Debate: One More Time

THE 40-YEAR-OLD CONTROVERSY over the use of fluoride in drinking water threatens to erupt from dormancy this month as the government gets ready to make public new data on fluoride’s cancer-causing potential. Since the 1940s, sodium fluoride has been added to toothpaste and public water systems to prevent tooth decay. Opponents have resisted the practice […]

Sicily: Accumulation of volcanogenic fluoride by vegetation: Mt. Etna, Sicily

Abstract: Fluoride was measured in samples of lichen and grass collected in 1987 from over 50 sites on the slopes of Mt. Etna. Raised levels of fluoridewere detected on the downwind, eastern side, indicating that the volcano’s plume is the principal source of the fluorides. Lichens proved to be more sensitive than grasses in determining […]
