Anti-fluoridation argument<br />
doesn’t ‘hold much water’<br />
Nick King<br />
responds to<br />
last week’s<br />
opinion piece<br />
by John<br />
Verd about<br />
the dangers<br />
of water<br />
fluoridation<br />
in Christchurch<br />
With respect John, I think<br />
your passion for the well-being<br />
of others is admirable but, in this<br />
case, misguided.<br />
To suffer a “toxic dose” of<br />
fluoride, at the current safe and<br />
recommended level you’d have to<br />
guzzle 25 gallons of water. You’d<br />
die from hyperhydration first.<br />
Sola dosis facit venenum – the<br />
dose makes the poison.<br />
You quote Hirzy and Connett<br />
as if that adds weight to the antifluoride<br />
argument.<br />
They are not respected in their<br />
field, nor do they speak for the<br />
(United States) Environmental<br />
Protection Agency. And they’re<br />
at odds with their peers and<br />
mountains of research.<br />
I suspect these “studies” are the<br />
well-known “Chinese studies”,<br />
popular among conspiracy theorists<br />
and widely discredited. Fifty<br />
poor studies versus thousands<br />
of more robust studies does not<br />
make a solid case.<br />
The Chinese studies fail to<br />
acknowledge the higher than recommended<br />
levels of fluoride and<br />
other chemicals (also other factors<br />
that may contribute to lower<br />
IQ), including arsenic and iodine<br />
– iodine being a good example<br />
of “beneficial in small doses,<br />
dangerous in higher doses”.<br />
The dose makes the poison.<br />
Even if it is a by-product of an<br />
industrial process, so what? Lots<br />
of things are. We call it recycling.<br />
It’s safe at the levels required to<br />
be beneficial to teeth.<br />
Sure, it might be classed as<br />
a hazardous product which, of<br />
course, it will be if you’re counting<br />
it by the truck load.<br />
Hydrochloric acid is highly<br />
corrosive, but is also produced<br />
naturally by your own body.<br />
There’s arsenic in rice.<br />

The dose makes the poison.<br />
I’m all for questioning and<br />
challenging the status-quo –<br />
things go stale if we don’t.<br />
But scaring people with<br />
sciencey-sounding rhetoric isn’t<br />
very helpful, even if your intentions<br />
are good.<br />
I too have my own reservations<br />
about this situation because of<br />
Christchurch’s reputation for<br />
amazing water, and I have an<br />
emotional attachment to that.<br />
But the points you covered just<br />
don’t hold much water (pun<br />
intended) and are potentially<br />
unnecessarily scary for people.<br />

Readers respond to last<br />
week’s opinion piece by<br />
John Verd about fluoridated<br />
water<br />
Pam Webber, Middleton<br />
I agree with you. (It’s)<br />
abhorrent that they intend<br />
ruining our beautiful<br />
Christchurch water. Keep up the<br />
good work.<br />
Ian Orchard, Papanui<br />
I won’t be losing sleep<br />
over the possibility of<br />
fluoridated water until I get<br />
some more details which<br />
John Verd omitted from<br />
his soapbox. The somewhat<br />
breathless revelation that<br />
hydrofluorosilicic acid (more<br />
properly Hexafluorosilicic acid)<br />
is a by-product of the fertiliser<br />
industry isn’t particularly<br />
relevant. Like sausages, lots<br />
of ingredients in food come<br />
from pathways that we prefer<br />
not to know about, without<br />
being in any way hazardous.<br />
On the other hand, plenty of<br />
ingredients can be dangerous<br />
in the wrong concentrations.<br />
Sodium chloride and<br />
dihydrogen oxide are two classic<br />
examples. Sodium bicarbonate,<br />
frequently recommended for<br />
tough cleaning jobs, is also an<br />
essential ingredient in cakes.<br />
John makes no mention of the<br />
concentration of fluoride ions in<br />
treated water. The World Health<br />
Organisation recommends<br />

1mg/l or one part per million,<br />
hardly a toxic dose for a mineral<br />
that doesn’t accumulate in<br />
the body. It’s much easier to<br />
scaremonger if you leave out<br />
any details that might counter<br />
your beliefs.<br />
Fee, Fendalton<br />
I am very annoyed that<br />
people do not have a choice with<br />
fluoridation. It’s mass poisoning.<br />
I certainly do not want to drink<br />
a neurotoxin everyday. What<br />
about babies and pregnant<br />
mothers? I would have to buy a<br />
special water filter that can get<br />
rid of fluoride. Children who<br />
have rotten teeth are most<br />
likely not drinking water and<br />
consuming too much sugar.<br />
Better to educate than fluoridate.<br />
Daniel Brice, Woolston<br />
I strongly support John<br />
Verd’s article on water<br />
fluoridation. It’s a poison and,<br />
like all things we ingest, it<br />
should be done of our own<br />
hand. I will be doing as much<br />
as possible to stop our precious<br />
water from being tainted with<br />
this chemical and having the<br />
choice taken from me of water I<br />
put into my body.<br />

I would hate to see<br />
Christchurch water fluoridated.<br />
I would be very concerned<br />
about residents’ health.<br />

and himself.<br />

homes including double glazing and plenty of insulation. Three bedrooms all downstairs<br />
