Provoque de graves brûlures de la peau et de graves lésions des yeux. Fluorosilicic acid (FSA), an inorganic fluoride compound, is a waste product of synthetic fertilizer production. Upon vaporizing, it decomposes into hydrofluoric acid (HF) and silicon tetrafluoride. This is the same for fluorosilicic acid in drinking water as the fluoride anion is the end product of its hydrolysis when added to water. Fluoridation and its Dangers ... (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. Due to its ease of use over competing technologies, hydroflurosilic acid is commonly used in water fluoridation applications. NACRES NA.21 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 is generally believed not to exist in the vapor phase, but only in solution. silicic acid, are considered, as is the debate about whether fluoridation increases lead in water, with the conclusion that there is no such increase. Piranha solution, or Caro's acid (H 2 SO 5), is like a voracious chemical version of the carnivorous fish.Except instead of eating small animals, this mixture of sulfuric acid (H 2 SO 4) and hydrogen peroxide (H 2 O 2) devours pretty much any organic molecule it encounters.Today, this acid finds its main use in the electronics industry. “In regard to the use of fluorosilicic acid as a source of fluoride for fluoridation, this agency regards such use as an ideal environmental solution to a long-standing problem. hydrofluosilicic acid - an unstable poisonous corrosive acid known primarily in the form of its salts fluosilicic acid acid - any of various water-soluble compounds having a sour taste and capable of turning litmus red and reacting with a base to form a salt Powered by Create your own unique website with customizable templates.

Hexafluorosilicic acid is an inorganic compound with the chemical formula H 2 SiF 6 also written as (H 3 O) 2 [SiF 6].It is a colorless liquid mostly encountered as diluted aqueous solution, from there, the second chemical notation also proposed. 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. Breathing FSA’s fumes causes severe lung damage or death; an accidental splash on skin leads to burning and extreme pain. DR. NABIL EBRAHEIM EXPLAINS THE CAUSES AND SYSTEMS OF LEAD POISONING. 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). Hydroflurosilicic acid, also known as fluorosilicic acid and hexaflurosilicic acid, is a clear, colorless liquid that is used in a variety of industrial applications. Sodium fluorosilicate: a dry salt additive, dissolved into a solution before being added to water.

Fluorosilicic acid (FSA), an inorganic fluoride compound, is a waste product of synthetic fertilizer production. The claim is false; experts say that only a very high level of fluoridated tap water or toothpaste consumption is toxic. Safety Information on Fluorosilicic Acid from a provider. The types of fluoride added to different water systems include fluorosilicic acid, sodium fluorosilicate, and sodium fluoride. 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. A very small amount of fluorosilicic acid is added at the treatment plant as a liquid, where it dissolves to release fluoride ion. 16961-83-4 24 Acute Tox. Emergency telephone numbers I May be fatal if inhaled or swallowed. 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.

DANGERS OF URBAN FLUORIDE. … Toxic effects are principally related to its corrosive properties. 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. Elemental fluorine is produced from it. The three artificial water fluoridation additives are fluorosilicic acid, sodium fluorosilicate (both silicofluorides) and sodium fluoride (CDC) All can contain contain lead when added to … Solutions and mists with a pH of 3 or less are a significant health concern. Piranha Solution . The argu­ ments of anti-fluoridationists and fluoridation propo­ nents are examined with respect to the politics of the issue. Fluorosilicic acid (CAS No.) Fluoride is now used in the public drinking water supplied to about 3 out of 4 Americans. 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. The decision to add fluoride to drinking water is made at the state or local level. This is the most common method of adding fluoride to drinking water supplies in Western Australia. Currently, the source of fluoride in most public water supplies is fluorosilicic acid, according to government records. In fact Roger D Masters (research professor of 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.
