But more and more emerging clinical research
demonstrates that antimicrobial silver – including colloidal silver
nanoparticles -- pose little-to-no threat to wildlife whatsoever. Indeed, in a brand new clinical study even
when mice were exposed to a whopping 5,000 ppm colloidal silver nanoparticles for
several days at a time, there were no toxic effects whatsoever.
Here’s information about the most
recent studies the radical anti-silver environmentalist hope you’ll never see…
Hi, Steve
Barwick here for www.TheSilverEdge.com...
Several weeks
ago in an article titled New Research: Silver Nanoparticles Not Toxic, I wrote about a brand new 2012
clinical study published in the prestigious journal Nanotoxicology…
…in which
researchers tested silver nanoparticles on adult guinea pigs for genotoxicity,
acute oral and dermal toxicity, eye and dermal irritation and corrosion, and
skin sensitization.
In these
animal tests, the researchers found there were no abnormal signs or mortality
from oral doses of 2,000 ppm nanosilver – an astonishingly high concentration
of nanosilver for a small animal like a guinea pig.
What’s more,
when the animals were sacrificed and examined microscopically, there was no toxicity
found, nor harm to the integrity of the cell’s genetic material. Nor was there any acute eye or dermal irritation
or corrosion when the silver nanoparticles were tested in the eyes and on the
skin of the animals.
This was an
acute study, meaning the research was conducted for only a short duration. But it did demonstrate that short-term
exposure to even excessively high concentrations of nanosilver caused basically
no harm to the animals tested.
Another New Study
Now in another
new animal study published in June 2011 in the Journal of Veterinary Medical Science, even higher doses of silver nanoparticles were used, this time on small mice.
And guess
what? Once again, researchers found no
significant harm to the little critters whatsoever.
Indeed, this
time concentrations of 5,000 ppm colloidal
silver nanoparticles were used. Keep in
mind that on average, most humans use between 5 ppm to 10 ppm colloidal
silver. Tiny mice being given a whopping 5,000 ppm
colloidal silver nanoparticles would be the rough equivalent of a human using 1,000,000
(yes, one million) ppm colloidal
silver!
And once
again, these excessively high levels of nanosilver produced neither mortality
nor acute toxic signs in the mice throughout the 24-hour and 72-hour
observation periods.
After the
mice were sacrificed and examined, the researchers concluded:
“In the hematological analysis, there was no
significant difference between mice treated with AgNPs and controls. Blood
chemistry analysis also showed no differences in any of the parameter examined.
There was neither any gross lesion nor histopathological change observed in
various organs.”
In other
words, these unbelievably high concentrations of silver nanoparticles didn’t
cause any internal problems whatsoever.
What’s more,
the researchers stated, “Percentage of
body weight gain of the mice showed no significant difference between control
and treatment groups.” In other
words, there was no loss of appetite, weight or other abnormal signs that might
indicate a toxic reaction.
The
researchers also concluded, “In acute eye
irritation and corrosion study, no mortality and toxic signs were observed when
various doses of colloidal AgNPs were instilled in guinea pig eyes during 72 hr
observation period. However, the instillation of AgNPs at 5,000 ppm produced
transient eye irritation during early 24 hr observation time.”
So
apparently there was a little bit of eye irritation when the researchers used
5,000 ppm colloidal silver nanoparticles directly into the eyes of the poor
little mice. But the irritation was
“transient,” i.e., it was only temporary, disappearing after 48 hours!
Finally,
the researchers concluded:
“Nor was any gross
abnormality noted in the skins of the guinea pigs exposed to various doses of
colloidal AgNPs. In addition, no significant AgNPs exposure relating to dermal
tissue changes was observed microscopically.
In summary,
these findings of all toxicity tests in this study suggest that colloidal AgNPs
could be relatively safe when administered to oral, eye and skin of the animal
models for short periods of time.”
Bye, Bye Enviro Hyperbole!
Studies like
these continue to refute the shrill contentions of the radical anti-silver
environmentalists who claim that exposure to even low levels of antimicrobial
silver have the potential to wreak havoc on little critters and other wildlife
in the environment.
Of course,
for millennia the environment has contained literally millions of tons of nanosilver in the form of trace
mineral silver that exists naturally. Indeed,
it has only recently been discovered by researchers that Mother Nature appears to make her own nanosilver, and is indeed the world’s most
prolific manufacturer of nanosilver.
And of course
none of this silver has ever harmed wildlife or caused any kind of environment
catastrophe. Indeed, the case could be
made that Mother Nature uses nanosilver to keep infectious microorganisms from
growing out-of-control in the environment.
So truth be
told, the real agenda of the radical
anti-silver environmentalists has nothing whatsoever to do with protecting wildlife
or the environment. Instead, their
entire agenda seems to be to strip consumers of the one safe, natural protection against infectious
microorganisms and disease that Big Pharma can’t control.
After all,
for years these same environmental groups that now oppose the use of antimicrobial
silver in consumer products have been taking
millions of dollars in contributions
from charitable foundations set up by Big Pharma.
And as you
know, Big Pharma hates antimicrobial silver with a passion. Indeed, it sees silver as the one substance that alleviate the spread
of infectious disease and ultimately destroy sales of its increasingly more
expensive prescription antibiotic drugs.
I’ll continue
to report on studies demonstrating the lack of toxicity of nanosilver to
wildlife and the environment as they come out.
After all, these are the very studies the environmentalists and their
cronies in the news media hope you’ll never see.
In the
meantime, I remain…
Yours for the
safe, sane and responsible use of
colloidal silver,
