Referring to a common salt of fluoride, sodium fluoride (NaF), the lethal dose for most adult humans is estimated at 5 to 10 g (which is equivalent to 32 to 64 mg elemental fluoride/kg body weight). [ 2 ] [ 3 ] [ 4 ] Ingestion of fluoride can produce gastrointestinal discomfort at doses at least 15 to 20 times lower (0.2–0.3 mg/kg or 10 to 15 ...
Ingested fluoride forms hydrofluoric acid in the stomach. In this form, fluoride crosses cell membranes and then binds with calcium and interferes with various enzymes. Fluoride is excreted through urine. Fluoride exposure limits are based on urine testing, which is used to determine the human body's capacity for ridding itself of fluoride. [69 ...
Soluble fluoride salts, of which sodium fluoride is the most common, are toxic, and have resulted in both accidental and self-inflicted deaths from acute poisoning. [4] The lethal dose for most adult humans is estimated at 5 to 10 g (which is equivalent to 32 to 64 mg elemental fluoride per kg body weight).
He believes that water fluoridation violates modern pharmacological principles, which indicate that medications should be tailored to individuals.[6] 4^ Fluoride in drinking water can cause cancer, Svenska Dagbladet (in Swedish) 5^ Torell P, Forsman B (February 1979). "[Arvid Carlsson's fluoride ponderings 1978]" (in Swedish).
Sodium fluoride (NaF) is an inorganic compound with the formula Na F.It is a colorless or white solid that is readily soluble in water. It is used in trace amounts in the fluoridation of drinking water to prevent tooth decay, and in toothpastes and topical pharmaceuticals for the same purpose.
Roholm conducted laboratory studies, interviewed cryolite workers, visited factories, and documented the progression of fluorine poisoning in humans and animals from gastrointestinal upsets, neurological disorders, and bleeding gums to the advanced cases of skeletal fluorosis and crippling arthritis.
People are ingesting borax. Also known by its chemical name sodium borate decahydrate, borax is a salt typically used to kill ants and boost laundry detergent, among other household cleaning needs ...
Fluoride's effects depend on the total daily intake of fluoride from all sources. Drinking water is typically the largest source; [13] other methods of fluoride therapy include fluoridation of toothpaste, salt, and milk. [14] The views on the most efficient method for community prevention of tooth decay are mixed.
