KURT FERRE, PORTLAND DENTIST, FLUORIDATIONIST
Kurt Ferre is a retired dentist in Portland who has been part of sneak attack efforts to impose fluoridation on Portland.
Portland is fighting back, and so is Snohomish County. The difference is that Portland has clean, uncontaminated drinking water while Snohomish County has had industrial grade toxic waste fluoridation materials (including lead, arsenic, mercury, cadmium, thallium, and orthosilicic acid) added since 1991.
I posted this article in the Edmonds and Mukilteo (Washington) Beacon, and Dr. Ferre responded.
Dr. Ferre says that fluorsilicic acid does not break down to form orthosilicic acid – which is important to the fluoridation discussion because orthosilicic acid is exceptionally good at dissolving lead in old service lines, copper solder, and faucets, all of which contain lead.
Ferre says “The orthsilic acid mentioned is a bunch of poppycock”. Instead, Ferre says that fluorosilicic acid breaks down into “fluoride, hydrogen, and a little silica”.
Dr. Ferre is not even close to right. The 2006 report on fluoridation issued by the National Research Council, the most prestigious research body in the US, said: “In drinking water at approximately neutral pH and typical fluoride concentrations, all the silicofluoride appears to be dissociated entirely to silicic acid [Si(OH)4], fluoride ion, and HF”. http://www.nap.edu/openbook.php?record_id=11571&page=53. The “little silica” is a lot of orthosilicic acid.
Dr. Ferre says nothing about the other elements which NSF admits can be present in fluorosilicic acid, nothing about the arsenic, cadmium, mercury, barium, and the radioactive thallium.
To neutralize the acidity of the fluorosilicic acid, Everett adds tons of soda ash, sodium carbonate, as alkalizer, enough to bring the sodium level up from zero to 7 ppm. However, the amount of alkalizer sufficient to neutralize the fluorosilicic acid is not sufficient to neutralize the orthosilicic acid.
Dr. Ferre cites the Environmental Sciences Technology article, 2006 Apr 15;40(8):2572-7, which can be found at http://www.ncbi.nlm.nih.gov/pubmed/16683594. This article does not support his position and supports my position in two more ways:
The article says: “The buffer capacity of all of these systems was found to be insufficient to prevent acidic shifts in pH when hexafluorosilicate was added.” This statement relates to the fact that it is hard to neutralize the daughter acids which fluorosilicic acid produces. It is not practical to add enough alkalizer to neutralize the orthosilicic acid. You could raise the pH to 10 and the orthosilicic acid would still be dissolving the lead out of our plumbing.
For more on orthosilicic acid see Dr. Sauerheber’s article at http://fluoride-class-action.com/silicic-acid.
Moreover, when we add soda ash as alkalizer, sodium carbonate, we are adding a large load of salt to our drinking water. We should not be adding salt to our drinking water.
The Environmental Sciences article also says: “The pH change is sufficient explanation for the observed inhibition of acetylcholinesterase that was previously attributed to hexafluorosilicate hydrolysis intermediates.” This is a reference to the fact that fluorosilicic acid (and the other contaminants it contains) is an acetylcholinesterase inhibitor, which is not good for health.

Comment from Dr. Richard Sauerheber, Ph.D.:
Mr. Deal understands basic chemistry better than Mr. Ferre does. Deal agrees with Ferre, that fluorosiicic acid diluted at pH 7 is fully dissociated. That was his point. It dissociates into fluoride ion and the weak acid silicic acid (with trace HF) as described by the NRC in 2006. The NMR article cited also confirms this.
But the point is that silicic acid is the ingredient involved in the leeching of lead salts in old plumbing as found in Seattle and Everett. The NMR article also confirmed that a complex, SiF5-, forms at pH below 3, which is a pH common in man and animal stomachs and this complex is assimilated, as is HF, the form of most of the fluoride at stomach pH.
And by the way, of course fluoride is fluoride in any substance, but that is an incomplete statement because the toxicity of fluoride is determined by its environment. Calcium fluoride is not a toxic compound, but all industrial fluorides lack calcium and are listed as toxic calcium chelators. If dentists used calcium fluoride for teeth treatments we would not be so concerned, and we would not have lost chidlren to heart attack who swallowed some of the gel. Fluoride in the presence of calcium behaves totally differently than fluoride in the absence of calcium, as in fluoride dental gels and as added into Everett water supplies.
And ingested fluoride from water produces only 0.02 ppm fluoride ion in saliva to topically bathe teeth (NRC), which is worthless for dental caries compared to toothpaste with fluoride at 75,000 times higher concentration. Systemic fluoride was ruled ineffective by the CDC in 2001, which is old news for most of us, but not for those who still promote its ingestion. The truth can hurt one’s stubbornness, but not acting on the truth can hurt most everyone else.
Fluoride is not listed in any Clinical Chemistry or Nursing or Veterinary Manual as a normal constituent of blood for a very good reason–it isn’t.
