Hydroflurosilicic acid, also known as fluorosilicic acid and hexaflurosilicic acid, is a clear, colorless liquid that is used in a variety of industrial applications. 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 Breathing FSA’s fumes causes severe lung damage or death; an accidental splash on skin leads to burning and extreme pain. In fact the relevant species is the fluoride anion whatever the source – NaF, CaF 2 or fluorosilicic acid. This is the most common method of adding fluoride to drinking water supplies in Western Australia. 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. Fluosilicic acid purum, 33.5-35% Synonym: Fluorosilicic acid, Hexafluorosilicic acid, Hydrogen hexafluorosilicate CAS Number 16961-83-4. 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. 2 (Inhalation:dust,mist), H330 Skin Corr. 1, Box 85-A, Jennings, FL 32053 Tel: 904-792-3975 email: gop@alltel.net November 18, 1998 This is a letter from a man who has several health problems related to his exposure to fluorides in the Fluoride is now used in the public drinking water supplied to about 3 out of 4 Americans. Upon vaporizing, it decomposes into hydrofluoric acid (HF) and silicon tetrafluoride. silicic acid, are considered, as is the debate about whether fluoridation increases lead in water, with the conclusion that there is no such increase.

Nocif en … Rt. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. Fluorosilicic acid (FSA), an inorganic fluoride compound, is a waste product of synthetic fertilizer production. 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. “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. PubChem Substance ID 57646695. NACRES NA.21 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. Powered by Create your own unique website with customizable templates. Elemental fluorine is produced from it. The claim is false; experts say that only a very high level of fluoridated tap water or toothpaste consumption is toxic. Linear Formula H 2 SiF 6. 1, H318 Aquatic Acute 3, H402 Water (CAS No.) 7732-18-5 76 Not classified Fluorides, as F 19 Not classified . Fluorosilicic acid Calcium hydroxide In its original form before it was cleaned, your tap water is linked to the water from the sewers, which of course is now being treated safely so X sewer water can now be drunk and is considered 100% clean! Dangers of Fluoridating Drinking Water with fluorosilic acid (H 2 SiF 6)/sodium fluorosilicate (Na 2 SiF 6) Author: Gary O. Pittman. ≤0.01% fluorosilicic acid ign. Causes severe … Fluorosilicic acid is also referred to as hydrofluorosilicate, FSA, or HFS. eCl@ss 38130308 . MDL number MFCD00036289. 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. 16961-83-4 24 Acute Tox. Dangers physiques Dangers pour la santé Dangers environnementaux Éléments d’étiquetage Mention d'avertissement Mention de danger Danger Peut être corrosif pour les métaux. Fluorosilicic acid is generally believed not to exist in the vapor phase, but only in solution. Piranha Solution . Silico fluorides Applied The fact that fluoridating Cleaning agents encompass Cause And thus very toxic arsenic Along with studies With Pros Plus Coplan, (1999) Present A fantastic Rapport from the many different fluorosilicic acid (and The fan's sodium salt) in fluoridated Cold water In addition a raise uptake To Topped To get into Kids blood. 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. A very small amount of fluorosilicic acid is added at the treatment plant as a liquid, where it dissolves to release fluoride ion. residue ≤5 ppm density 1.15 g/mL at 25 °C (lit.) DR. NABIL EBRAHEIM EXPLAINS THE CAUSES AND SYSTEMS OF LEAD POISONING. May be fatal if inhaled or swallowed. Emergency telephone numbers I 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 URBAN FLUORIDE. 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). Molecular Weight 144.09 . Toxic effects are principally related to its corrosive properties. Houstoi?, Texas 77098 1.4. Breathing FSA's fumes causes severe lung damage or death; an accidental splash on skin leads to burning and extreme pain. 1A, H314 Eye Dam. The types of fluoride added to different water systems include fluorosilicic acid, sodium fluorosilicate, and sodium fluoride. 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 … The argu­ ments of anti-fluoridationists and fluoridation propo­ nents are examined with respect to the politics of the issue. 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 decision to add fluoride to drinking water is made at the state or local level. Urban fluoride (FLUOROSILICIC ACID) affects the body and brain. Safety Information on Fluorosilicic Acid from a provider. 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. Due to its ease of use over competing technologies, hydroflurosilic acid is commonly used in water fluoridation applications. 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. 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.

Fluorosilicic acid: a water-based solution used by most water systems in the United States. 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. Sodium Fluoride and Fluorosilicic Acid, two synthetic byproducts of industrial waste both used in the fluoridation of public water, ... Opposers of fluoridation claim that the government issuance of a lower threshold is evidence that the dangers of fluoridation are becoming more evident. 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. Sodium fluorosilicate: a dry salt additive, dissolved into a solution before being added to water. Solutions and mists with a pH of 3 or less are a significant health concern.
