UK Against Fluoridation

To the editor:
The City Council defeated an ordinance that would have banned fluoridation of our water.
I would encourage residents who get their water from Golden Heart, College Utilities or Water Wagon to educate themselves on the dangers of fluoridated water. An excellent article with many scientific references can be found at www.slweb.org/limeback.html.

This article was written by the President of the Canadian Association for Dental Research, a dentist who had supported water fluoridation for many years but now is a knowledgeable, vocal opponent to water fluoridation.

In researching this issue I have found that there is a huge difference between naturally occurring fluorides in drinking water (calcium fluoride leached from soil at high levels that cause teeth effects) verses artificially synthesized fluorides such as sodium fluorsilicate (the compound that Golden Heart/College Utilities uses to fluoridate our water).

The safety of naturally occurring calcium fluoride can be compared to artificially synthesized sodium fluorsilicate by checking their “LD50” values.

LD refers to Lethal Dose and LD50 refers to the amount of a substance (in milligrams per kilogram of body weight) that results in the death of 50 percent of the lab animals tested.(LD50’s are listed on Material Safety Data Sheets for most compounds.) The larger the LD50, the safer the substance, the smaller the LD50, the more toxic the substance.

A comparison of the sources of fluoride is enlightening:

1. Naturally occurring calcium fluoride has an LD50 of 4,250.

2. Sodium fluorosilicate (the additive that GHU adds to our water) has an LD50 of 125.

3. Arsenic has an LD50 of 763.

In other words: sodium fluorosilicate is 34 times more toxic than naturally occurring calcium fluoride and six times more toxic than arsenic!
