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. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. Elemental fluorine is produced from it. Toxic effects are principally related to its corrosive properties. 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. 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. This is the most common method of adding fluoride to drinking water supplies in Western Australia. silicic acid, are considered, as is the debate about whether fluoridation increases lead in water, with the conclusion that there is no such increase. 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. 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. 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. In fact Roger D Masters (research professor of Provoque de graves brûlures de la peau et de graves lésions des yeux. Solutions and mists with a pH of 3 or less are a significant health concern. 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 fact the relevant species is the fluoride anion whatever the source – NaF, CaF 2 or fluorosilicic acid. VIOLENT OFFENDERS HAVE SIGNIFICANTLY HIGHER LEVELS OF LEAD. Hexafluorosilicic Acid is generally immediately available in most volumes.
