"Soluble fluoride compounds, such as sodium fluoride and sodium silico-fluoride, are completely absorbed in the gut [2, 3]. Less soluble compounds,
including calcium fluoride and fluorapatite (bone meal) are partially absorbed; as much as two-thirds of ingested fluorapatite is present in feces
[4]."
http://www.nature.com/ki/journal/v7/n3/abs/ki197519a.html
"Some of this extra fluoride comes from the fluoridated water used to manufacture dog food. Most, however, is from the "bone meal" and various meat
byproducts that are added to dog food - anything from "chicken byproduct meal" to "beef and bone meal."
"Combined fluoride exposure from both food and water can easily range into unsafe territory. Routine exposure, like eating the same food every day,
can predispose dogs to a variety of health problems: weakened bones, hormonal and behavior problems, and even bone cancer."
http://www.enviroblog.org/2009/07/is-there-too-much-fluoride...
In 1963, Dow stated that:
“Under no conditions should sulphuryl fluoride be used on raw agricultural food commodities, or on foods, feeds or medicinals destined for human
or animal consumption.” (Bond 1984) (emphasis added)."

...um... for fear of swinging this discussion back to the original topic....
I agree that most chemicals are cheaper to buy than make. This topic was an attempt to brainstorm ideas for one source of flouride/flourine that
could be accumulated instead of thrown away, then one day getting around to extracting that source. If a typical filter doesn't accumulate much then
this source is worthless. I am just trying to squirrel away ideas for chemicals that may one day be banned out right (this list is growing) or when
it may be worth it financially one day.

The other day I was rinsing off some pretty purple fluorite crystal clusters, some ~2.5 cm cubes fused together and noticed a sulfur smell. Anyway
here's some tidbits I came across.
"Fluorite is the most popular mineral for mineral collectors in the world, second only to quartz. Every mineral collection owned by even the newest
and youngest of mineral collectors must have a specimen of fluorite. Fluorite is by far one of the most beautiful and interesting minerals available
on the mineral markets."

I have thought about the subject a lot in the last few years. I have to say you need to read the two threads linked below. Very good place for ideas.
Also, study the threads (some are at top in their sections - sticky's) concerning synthesizing various chemicals. Some over 40 pages but worth your
time to study.

Indeed, you did.: specifically
"Hydrofluorosilicic acid, Sodium Fluoride, Sodium Hexafluorosilicate. I find it astounding anyone claiming to be knowledgeable chemists are defending
putting this poisonous crap into drinking water. I barely tolerate taking a shower in this evil brew and don't even make ice cubes unless it is
composed of spring water. You know, the natural stuff filtered far better by nature which humanity survived on for thousands of years."
Now, the problem with that is that natural spring water (like where my aunt grew up) contains more fluoride than fluoridated water.
So, you are claiming that "natural" water is safer even though it contains more of the stuff you are complaining about.
Then you went on to pretend that Cr(VI) is unnatural.
Specifically you said "Hey, Chromium is good for the body also. Right from natural sources. Was that naturally produced III or man made VI? "
And, re "Justify calling me nuts for merely stating I would not drink water with Fluorine added to it. "
No, that's the point. You get called nuts because you say things that are ridiculous.
One example would be your insistence that "natural is good". Another example would be that you think anyone called you nuts because of the water you
drink. Nobody did.
So, it's not really name-calling, it's valid observation.
It's also clear that, since Blogfast got the impression that you are nuts a while back (as he said he did) then it can't be due to something recent
like your ideas about fluoride. Did you not realise that?
You didn't? I guess you must be nuts then.

Fluoride and bone disease in uremia

water generally contains 53 moles (1 part per million or 1 mg/liter) of fluoride."

there's not much to quibble with, some but I would welcome any comments after you view this. At the end I almost closed out the video but a few other
tidbits are brought up so wait till it ends completely. Some very good details to ponder no matter what side of the fence you are on. Again, this

1 -2 gallons... (note also the cautious caveat 'can')
Now can anyone show me a demonstrable case of fluorosis caused by drinking fluorinated water? From using fluorinated toothpaste? If not kindly put up
or shut up.
This is a typical case of irrational fears based on an invisible bogeyman, with some vaguely ideological anti-statism thrown in. The rest is fluff.

Well, that's nearly an answer to the OP. Don't try to extract fluoride from tap water there's very little there.
Extract it from tea instead because it's a much more concentrated source.
I'd still just buy the stuff on ebay.

At the current price of tea, fluorides extracted from it would probably cost as much as gold, in raw materials alone.

Yes, something you have trouble with while jumping in to attack and insult me, while defending someone else's insults. "So, you are claiming that
"natural" water is safer even though it contains more of the stuff you are complaining about."
No, quit blowing the claims of others out of proportion. I said paraphrasing, I do not believe people should be forced by mandate to have man made
chemicals put in their bodies, and that I prefer things from nature. You are the one jumping to conclusions drawing opinions from extreme examples. I
asked you to state assays of your aunts water and your tap water so we can compare in a scientific way. Without this data you are merely spewing
opinion. You have no scientific credentials made evident to anyone so if you are going to call me nuts I suggest you quote studies actually done by
credentialed authorities. Also you should include opposing studies by equally credentialed sources so we can make fair assessments of the available
data. Otherwise your opinion means nothing to me. My point is adding these chemicals is a bad idea when long term studies of harm not immediately
apparent is not done, nor well understood. Who is to say 2 generations from now cancers will not occur which otherwise would not have. People are not
being given a choice by mandate these chemicals are being forced on them. And for what reason? Because someone may not brush their teeth? If people
are too lazy or too ignorant to care for themselves is not justification in my mind for the entire population to be forced to drink such harsh
chemicals. You are defending the indefensible without providing valid scientific data to back your position up, and resorting to names and
insinuations to me for being in disagreement.
I am not going to waste more time talking to you on this subject, as that really would be, 'nuts'.

Well, that was a whole lot of vitriol.
Anyway, IrC, if you prefer things from nature, then have a spoonful of some villaumite, or fluorspar. They're all-natural, and I'm sure you'll love
them.
The problems with your argument that we shouldn't be forcing fluoride on the poor civilians is that
a) Local, not federal or even state, legislation decides whether fluoride should be put into water
b) Fluoride tends to leave the body readily
c) Even if it didn't, at the levels in water the national standard is set, a person would have to drink over 800 liters to feel anything, and by then
they'd be long dead from water toxicity.
So, IrC, what scientific credentials do *you* have? After all, one must have an extensive set of credentials to have an opinion, especially on the
Internet.

Recall outdoor workers, athletes, and diabetics are often drinking more water than others. People with kidney disease, as well as a few percent of the
population more sensitive to fluorides might also be more vulnerable. If you want to buy sodium fluoride tablets, you need a prescription. But it's OK
to put it in water at 4 ppm and then they decided not too long ago that that level was too high. And yet it wouldn't be that difficult to triple that
number if you ate the wrong foods and drank twice as much water along with beverages that contain fluorides.
Yesterday there was a documentary on football injuries, and some of the panel were former players with concerns of painful complications from playing
football, head injuries included. Some other players I have seen in the past wished they never played the pain was so bad. And just like this boxing
is also coming under scrutiny. I once watched a spliced clip of several boxers who died in the ring or shortly after from being hit in the head. You
just have to wonder how smart it is to promote these activities, because someone is getting hurt, damaged for the rest of their lives, literally
losing the use of their brain. So many things in life are disguised, look how long it's taken for someone to even begin to care. So when you're old,
maybe a lifetime of fluoride accumulation will matter, if you're taking in double or triple the norm or someone with a health problem. Maybe you could
have had a better ending.
Kidneys - Not everyone is alike.
"Approximately 50% of the fluoride ingested each day is excreted in the urine although it may be as low as 10–20% or as high as 60–70%, depending
on several factors
including age and urinary pH. Among the halogens, the excretion of fluoride by the kidneys is unusually rapid. Its renal
clearance from plasma typically ranges from 25–50 ml/min which is several orders of magnitude higher than that of other halogens. The clearance of
fluoride is positively related to tubular fluid pH indicating that reabsorption from the renal tubules occurs as the highly diffusible and permeating
molecule, HF. Thus, factors that influence urinary pH will also affect the excretion of fluoride. Such factors include the composition of the diet,
certain metabolic or respiratory disorders, alkalinizing or acidifying drugs and residence at high altitude."
http://www.sso.ch/doc/doc_download.cfm?uuid=9553230ED9D9424C...
"The reason for the limited transfer of F from plasma to breast milk is unknown. It has been suggested that the physiological plasma-milk barrier
actively protects the newborn from the toxic effects of F (Ekstrand et al, 1981). Cow’s milk, like human milk, contains low levels of F (0.017 mg/L)
even when F is added to the cow’s food or drinking water (McClure, 1949). Breast-fed infants (or infants bottle-fed with cow’s milk) are in
negative F-balance: more F is excreted in the urine than is ingested in the diet. During the period of breast feeding, F (deposited in foetal bone
during pregnancy) is mobilized and released into the extracellular fluids and subsequently excreted into urine. Therefore, early human development has
always occurred in a virtually F-free milieu even in the high-F areas: a phenomenon which lasts until the age of weaning and the introduction of solid
foods."
"In contrast, the F-intake to bottle-fed infants living in fluoridated areas depends upon the [F] of. a) the water used to reconstitute the feed; b)
the powdered formula-feed itself. Bottle-fed infants in fluoridated areas can receive 1.1 mg F from day 1: 150-200 times more F per day than
breast-fed infants, i.e., 1100 vs. 5-10 j.tg/day (Ekstrand, 1989). The normal pharmacokinetics of F during infancy is reversed. Bottle-fed infants in
fluoridated areas retain more than 50% of the ingested F-dose in the mineralizing tissues (Ekstrand et al, 1984; 1994)."
Of possible interest
"By old age, the pineal gland has readily accumulated F and its F/Ca ratio is higher than bone."
Fluoride deposition in the aged human pineal gland.

Why do I have the feeling that ANYTHING with the word 'liberty' in it would have your approval? Presumably that would also include the 'liberty' to
do demonstrably harmful things, as long as those 'liberty hating regulators and assorted do gooders' keep their mits of that kind of 'freedom'? When
people keep cracking on about 'tyranny', 'Hollywood' etc the only thing they 'achieve' is to diminish the meaning of the word 'tyranny'. You woudn't
recognise a real case of oppression if it came crawling out your nose.
Yous is essentially an uninformed, ideological stance. Libertarians, you've gotta love'm: couldn't organise a pissup in a brewery.

blogfast, did you watch the video? it has nothing to do with tyranny .
but i guess you associated mr jones' channel with ranting about tyranny, which is normal, as he does talk about it a lot.
Jones doesn;t even talk in the video, it's one of his employees, then there's an interview with an actual chemist who's opposed to fluoridation. and
my opinion is that both of them make very good points.
I don't consider my self libertarian i actually don't quite know what that means, but i see that word a lot on the internet. 
Yes I am uninformed,, i never claimed to be informed. compared to all the knowledge in the world I know 0% as a limit. but for example compared to
others my age in my country, i consider myself informed.
But on this forum i am in the bottom section, i say that sincerely, i am often dumbfounded by the sheer level of knowledge of many members here ,
especially of course in the realm of chemistry. you're one of those by the way..
ideological stance? i give you my word I have no fetish for liberty
And i would recognize tyranny as we only got out of it for 23 years. though i only lived in it for the first 2 years of my life, i heard a lot about
it from others.

My fluridated toothpaste contains only 0.5% NaF, so I think the suggestion to extract F from acid quality fluorite containing 98% F makes alot more
sense. That is one of those mineral ores worth paying the shipping for to perform such an extraction... especially if I was only going for 99% purity
anyway 
It is useful to observe government trends as tending toward more or less freedom, this will indicate trending toward liberty, or tyranny. Whether we
are at full 100% oppression is not the point, the trend in that direction is the point. The important thing often missed is that with freedom needs
to be allowed individual responsibility as well. Much better to have the individual or at least local community choice whether or not to do something
than have it forced on you, even if it is someone else's beilief it is good for you, whether or not it is good for you. The trend we have today is
tending toward less freedoms and less individual responsibility. The trend toward banning chemical compounds is a noteworthy indicator, the canary in
the mine. We know we are in trouble when they start banning whole classes of compounds, such all oxidizers, all organic solvents, etc.
What would be wrong with simply providing the available information to the public about fluoride and letting individuals decide if they want to use
fluoride toothpaste or not? I was a little dissapointed when I learned that my home water filter probably doesn't take out much of the flouride. I
am not worried about the toxicity, I am worried about someone else imposing their decision of what is for my own good, and providing me with no
choice, making me pay for it with my own taxes. Argue whether or not it is a net benefit until you are blue in the face, what's wrong with letting
people decide for themselves?

There's nothing wrong with that but there's also the argument in favour of the greater good. We also have mandatory vaccination against certain viral
diseases. Would you argue that the individual should choose whether or not to vaccinate their children? It's very easy to drive the argument about
individual freedom to absurd heights. In any society there is such a thing as the 'common good'.
If you don't accept that [at the level of a state], you end up living in gated communities where either a 'council of elders' or some majority will
decide what's allowed and what's not, what should be done and what not.
Whether we like it or not, Homo Sapiens is a social species.

Yes blog, I agree with you completely. It will always be a big compromise. I am simply very strongly in favor of more individual responsibility and
more freedom, rather than less freedom and the state taking care of more of people's needs, when people have individual needs. I think there needs to
be a balance, I am unhappy with the trending imbalance of individual freedoms across the globe. It will always be an imperfect compromise. For
example the knee-jerk trend toward banning chemicals might stop a few drugs being made, but it isn't going to make the small percentage of bad people
good. It will however have, what are hopefully unintended, negative consequences on society, such as squashing budding interests in chemistry, and
pointless chemophobia in greater society.
Imagine a world where only large corporations make everything people need, the average person has no idea how anything is made, perfumes, food,
building materials, paint, etc.. A world where kids are all sitting in chemistry class watching videos of other people experimenting instead of doing
it themselves so the school can avoid the liability from chemophobic parents freaking out, missing out on the smells, the little mistakes, not really
learning as much. Oh wait, that sounds strangely familiar.....

Can we, at least, nail the one about athletes and outdoor workers who drink a lot of water.
It's because they sweat a lot.
Guess what, the (very soluble) fluoride ion is excreted in sweat so these people are not at elevated "risk".
http://books.google.co.uk/books?id=I6RwOKkPX28C&pg=PA92&...
Wouldn't it have been better if you had looked at the facts before posting about outdoor workers and athletes?
There is a valid discussion about the relative merits of individual and state responsibility: but it has little or nothing to do with the case of
fluorides where there is no evidence of harm.
Sure, if you soak tea in water you can get high fluoride concentrations- well then don't.
Sure, at high doses, fluorides are toxic: so is water.
As I said before, show me the epidemic or accept that there isn't one.

In Britain there’s the infamous case of a doctor who claimed to have found a link between the MMR combination vaccine and autism in children.
Despite scant evidence for his case the doctor got quite a following and vile accusations against the government where the order of the day.
The doctor later fully recanted, stating he no longer believed his research (which appeared to be totally honest) showed any link. The followers
concluded he had been ‘leaned on’ and that there was a ‘cover up’. Today a few leading nutters are still campaigning against the MMR vaccine.
In the absence of expertise or real knowledge many people still prefer rhubarb.

"Can we, at least, nail the one about athletes and outdoor workers who drink a lot of water."
As long as there are no diabetic athletes or outdoor workers with bad kidneys or metabolic diseases I guess not. Oh but wait, I forgot to read all the
facts. Intuitively it would seem the more you take in, the more you might be concerned, for a variety of reasons. I think a good way to look at it is
that the body is like a new house, but as with everything little things start to go wrong, seemingly insignificant but over time all the collective
insults from nature start to add up. And like the boxer or football player manifesting a hit/illness later in life, it's all about how you played the
game. Not everyone is alike.
The McClure study 1945,
Both studies were compromised by the small number of subjects."
Page 7
"In tropical climates during prolonged exercise, the
excretion of fluoride in sweat is about a tenth of a
milligram. This values is quite small compared to 2
mg uptake from diet and a milligram of fluoride
excreted by urine."
http://student.ahc.umn.edu/dental/2012/5302/2009-L6-3Apr.pdf
Tidbits from the above link.
"The absorption of F taken on a fasting stomach was about 100%. Taken with milk decreased absorption to about 70%, and 60% with calcium-rich
breakfast. The decreased absorption is caused by the binding of fluoride with certain positive ions, esp Al, Mg, Ca. In this case, the fecal excretion
of fluoride increases. The ability of calcium to reduce the absorption of F is the basis for treating acute F toxicity by giving calcium-containing
solution."
"This experiment, rats were given Cimetidine to inhibit gastric acid secretion or Pentagastrin to stimulate gastric acid secretion. The
bioavailability of fluoride in the Pentagastrin group was 65-97%, comparing to 66% in the Cimetidine group. This study indicates that the permeation
of fluoride through the gastric mucosa is pH dependent. The higher acidity of stomach content increases the absorption of fluoride. The reason is
because HF is the dominate form at low pH."
"Fluoride is absorbed as HF, which is an uncharged molecule and can readily pass through biological membranes. Research has shown that 40% of oral
dose of fluoride is absorbed from the stomach."
"In case of acute fluoride poisoning, to promote the
renal excretion of fluoride by increasing urinary flow
rate will be effective only if the method also increases
urinary pH."
"Factors that influence urinary pH affect the excretion of
fluoride. For example, the composition of diet, certain
drugs, and some metabolic diseases. Interestingly, a
vegetarian diet promotes more alkaline urine and hence
more fluoride excretion."
