Arsenic is a toxin, yet it is also considered by some to be an essential nutirent. Here is an article from the latest Discover magazine that discusses hormesis. And SOME even recommend fluoride treatments. We now know that they pose unwarranted risks and provide little or no beneficial effect. SOME even used to sell snake oil, but it wasn't rather useful as we now understand.
I defy you to find a quote from any well known toxicologist that say ANY amount of a toxin is too much.
Acceptable limits are set so as to define where a KNOWN toxic reaction will more than likely occur if that limit is exceeded. ANY amount of toxin is still more than one would WANT to consume. In my book, if I can AVOID a toxin, I avoid it.
Can you give an example? Of course not, because, as I said MOST of the country has naturally occurring fluoride in the water.
Although calcium fluoride may well be common in water, it is only in SOME areas where there are high concentrations. And the relation to fluoride in general remains unchanged, whereas the studies indicate that a high exposure to fluoride DOES in fact result in lower IQ.
In relation to naturally occuring fluoride, I'll give you some links on that...
From Fluoridation 101
At the turn of the last century, many residents of the Southwest US had unusually ugly teeth. They called it "Colorado Brown Stain." Dental researchers sought to discover the source of this disfiguring tooth malformation. The culprit was high levels of fluoride in the water. Since these ugly teeth resisted decay, well-meaning but misguided dentists assumed the fluoride also caused the teeth to resist decay. However, what they overlooked is significant. The water supply was also very high in calcium and magnesium, essential nutrients we now know makes teeth strong.

I'm a dentist. I've forgotten more on this subject than you'll ever know.
Then maybe I should help you refresh your memory.

And SOME even recommend fluoride treatments. We now know that they pose unwarranted risks and provide little or no beneficial effect. SOME even used to sell snake oil, but it wasn't rather useful as we now understand. Could you expand on this point? I have no idea what you are trying to say here.

NO. NO. NO! We consume "toxins" every day. Do you eat foods with salt in them? OF course you do. But chlorine is a toxin, yet I don't see anybody recommending we completely stop using salt.
Once again, I'm dealing with science, not hysteria. Show me a toxicologist that denies the axiom "the dose make the poison".
Do you support congress trying to lower the arsenic levels in water?
Although calcium fluoride may well be common in water, it is only in SOME areas where there are high concentrations.
And now you prove you know NOTHING about chemistry. When calcium fluoride, or scilicofluoride, or any other fluoride compound gets into water, the fluoride ion dissociates from the other compounds in the molecule. Therefore a fluoride ion from one compound is exactly the same as a fluoride ion from another compound.
You should study basic chemistry before you try to debate this stuff.
And the relation to fluoride in general remains unchanged, whereas the studies indicate that a high exposure to fluoride DOES in fact result in lower IQ.
Please, lets stick to normal levels of fluoride. I know leaving out fluoride poisoning cases VASTLY limits your argument, but uing those cases is like using chlorine poisoning deaths to ban table salt.
The fact of the matter is that fluorine is the 13th most common element on the planet. It is in practically ALL water supplies, and it is at or over the recommened limits in around 30-40% of the country. So there are tens of millions of people who have fluoride in their water, and have had it in their water since we got here. Why aren't they sick?
Then maybe I should help you refresh your memory.
Only after you take a remedial chemistry course.
And I should say, I've been on all the anti-fluoride sites. The reason I joined FR back in 99 was to counter some of these lies in a post I saw. So there's nothing you've posted that I haven't seen or debunked.
