Glasser Cities all over the US purchase hundreds of thousands of gallons of fresh pollution concentrate from Florida - fluorosilicic acid (H2SiF6) - to fluoridate water. Dangers of Fluoridating Drinking Water with fluorosilic acid (H 2 SiF 6)/sodium fluorosilicate (Na 2 SiF 6) Author: Gary O. Pittman. 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. The types of fluoride added to different water systems include fluorosilicic acid, sodium fluorosilicate, and sodium fluoride. Emergency telephone numbers I Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. 1A, H314 Eye Dam. In fact Roger D Masters (research professor of FLUOROSILICIC ACID Hexafluorosilicic acid Dihydrogen hexafluorosilicate Fluosilicic acid Hydrosilicofluoric acid F 6 H 2 Si Molecular mass: 144.1 CAS # 16961-83-4 RTECS # VV8225000 ICSC # 1233 UN # 1778 EC # 009-011-00-5 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. 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. May be fatal if inhaled or swallowed. Fluorosilicic acid (CAS No.) 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. DR. NABIL EBRAHEIM EXPLAINS THE CAUSES AND SYSTEMS OF LEAD POISONING. Solutions and mists with a pH of 3 or less are a significant health concern. 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. The decision to add fluoride to drinking water is made at the state or local level. 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. 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. residue ≤5 ppm density 1.15 g/mL at 25 °C (lit.)
