Does this 10 gram figure take into account the 90+% in 24 hours
elimination rate of silver?
[Funny that they would state that humans retain 10% rather than eliminate
90%]
[Would that be 10 grams of 'retained' silver?]
"The biological half-life in humans (liver) ranges from several to 50 days
(9)" [How many is several?]
"In humans, under normal conditions of daily silver exposure, retention
rates between 0 and 10% have been observed (5)."
[ Does that mean that, at worst, in 50 days, half of whatever silver was
retained has been eliminated and there may be no retained silver to
eliminate and , at worst, the retention would be 10% of the intake...AND
we're talking about silver compounds?]
"Silver may be absorbed via the gastrointestinal tract, lungs, mucous
membranes, and skin lesions (5). The absorption rate of colloidal silver
after oral application can be as high as 5%" [Humm, is exposure, intake,
absorption and retention the same thing? Gosh, They make it really hard to
figure out what they're saying when they change what they're talking about
with every sentence. This is a technical report?]
"Argyria has been described in syphilitic patients in poor health who were
therapeutically dosed with a total of about 1 g of silver in the form of
silver arsphenamine together with other toxic metals." [Interesting ..1
gram of silver as compounds together with other toxic metals over a period
of, what, a day or so? a week? How long is a therapy? OH, I see it was
a single injection. Shall we dissolve a .22 caliber silver bullet and
stick it into our arms and 'maybe' have a problem , 'if' we're very sick
and had been treated with other toxic metals?]
What is arse-phenamine? The first syphilis cure that actually worked was
an arsenic compound. [Plain old arsenic worked too, but made people
insane.] I believe the inventor got a Nobel prize for it [see chemical
bullets]. ...could that be the "other toxic metals" mentioned?
7. Conclusions
"
"There have been no reports of argyria or other toxic effects resulting
from the exposure of healthy persons to silver."
Sounds like:
We're pretty darned safe.
That silver does work , both to treat water and diseases [they used it,
right? ...or was it the arsenic?]
That "colloidal silver" was mentioned only once in a context that implied
that this form was the least dangerous of all forms of silver.
That harmful doses of silver in any form are almost big enough to make
bullets out of.
"4.5 mg of silver per kg of body weight per day for 125 days....218 days
of exposure, albino rats receiving approximately 60 mg of silver per kg of
body weight per day "
[Golly! That's a total of 5,625 and 13,080 mg of silver per
kg! Warning...don't eat your electrodes if you weigh as little as a huge
rat.]
[ ;-)..OK, being silly.]
That changes in context between statements makes understanding reports
difficult. [So, anyone can read into it whatever they want to?]
