Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. Hydroflurosilicic acid, also known as fluorosilicic acid and hexaflurosilicic acid, is a clear, colorless liquid that is used in a variety of industrial applications. The argu­ ments of anti-fluoridationists and fluoridation propo­ nents are examined with respect to the politics of the issue. Fluorosilicic acid is a waste product of the phosphate fertilizer industry and is heavily contaminated with toxins and heavy metals (including the cancerous arsenic, lead and cadmium) and radioactive materials. Fluorosilicic acid: a water-based solution used by most water systems in the United States. Breathing FSA’s fumes causes severe lung damage or death; an accidental splash on skin leads to burning and extreme pain. Fluorosilicic Acid, 23-25% Silicate (2-) Hexafluoro-dihydrogen Hydrofluorosilicic acid, fluosilicic acid, HFS, FSA H2SiF6 144 16961-83-4 None Chemical intermediates, Water fluoridation Solvay Fluorides, LLC PO BOX 27328 Houston, TX 77227-7328 3333 Richmond Ave. Fluorosilicic acid is generally believed not to exist in the vapor phase, but only in solution. The decision to add fluoride to drinking water is made at the state or local level. Molecular Weight 144.09 . DANGERS OF URBAN FLUORIDE. PubChem Substance ID 57646695. Dangers of Fluoridating Drinking Water with fluorosilic acid (H 2 SiF 6)/sodium fluorosilicate (Na 2 SiF 6) Author: Gary O. Pittman. Breathing FSA's fumes causes severe lung damage or death; an accidental splash on skin leads to burning and extreme pain. Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water.Solutions of HF are colourless, acidic and highly corrosive.It is used to make most fluorine-containing compounds; examples include the commonly used pharmaceutical antidepressant medication fluoxetine (Prozac) and the material PTFE (Teflon). 16961-83-4 24 Acute Tox. The petition calls for the EPA to instead require the use of pharmaceutical-grade sodium fluoride in water fluoridation, which is the addition of fluoride to drinking water for the purpose of preventing cavities. Rt. Piranha Solution . An image purporting to show the dangers of fluoride in tap water by comparing it to the fluoride concentration in inedible toothpaste has been shared on Facebook. The claim is false; experts say that only a very high level of fluoridated tap water or toothpaste consumption is toxic. 3 (Oral), H301 Acute Tox. Due to its ease of use over competing technologies, hydroflurosilic acid is commonly used in water fluoridation applications. The conventional wisdom, however, has been that if a buffering agent is added simultaneously with the fluorosilicic acid, the finished water would not have a corrosive effect. In fact the relevant species is the fluoride anion whatever the source – NaF, CaF 2 or fluorosilicic acid. 2 (Inhalation:dust,mist), H330 Skin Corr. Urban fluoride (FLUOROSILICIC ACID) affects the body and brain. Safety Information on Fluorosilicic Acid from a provider. MDL number MFCD00036289. Fluorosilicic acid (FSA), an inorganic fluoride compound, is a waste product of synthetic fertilizer production. This is the most common method of adding fluoride to drinking water supplies in Western Australia. Sodium fluorosilicate: a dry salt additive, dissolved into a solution before being added to water. ≤0.01% fluorosilicic acid ign. Since the addition of fluorosilicic acid is known to increase the acidity of water, concerns that fluoridating water with fluorosilicic acid have been voiced for many years.

Fluorosilicic acid is also referred to as hydrofluorosilicate, FSA, or HFS. Le règlement REACH vise à renforcer la protection de la santé humaine et de l’environnement contre les risques que peuvent engendrer les produits chimiques. Along with the severe life-threatening dangers to health listed on the first page (repeating what we have covered), it lists fluorosis: Long-term exposure to Silicofluoric Acid can cause the deposit of Fluoride in the bones and teeth, a condition called Fluorosis. Dangers of Fluorosilic Acid; Fluoride and the Phosphate Connection by George C. Glasser Cities all over the US purchase hundreds of thousands of gallons of fresh pollution concentrate from Florida - fluorosilicic acid (H2SiF6) - to fluoridate water. VIOLENT OFFENDERS HAVE SIGNIFICANTLY HIGHER LEVELS OF LEAD. fluorosilicic acid (a compound of fluorine, hydrogen and silicon). Fluorosilicic acid (FSA), an inorganic fluoride compound, is a waste product of synthetic fertilizer production. Silico fluorides used as fluoridating agents contain lead and carcinogenic arsenic and studies by Masters and Coplan, (1999) show an association between the use of fluorosilicic acid (and its sodium salt) in fluoridated water and an increase uptake of lead into children's blood.
