Ethylmercury vs. Methylmercury
[Ethylmercury is found in vaccines. When the toxicity of Methylmercury is produced vaccinators will usually counter with the comment Ethylmercury is totally different and safer.]
Several pages of the paper examine the toxicity of methylmercury and its past
use as a fungicide. We are led to believe that this form of mercury is much
different than ethylmercury, the type found in vaccines. This is in spite of the
fact that ethylmercury was used for the same purpose. In fact, Ethylmercurric
Chloride, the material used as a fungicide (which was banned long ago) is what
is used to make thimerosal. This can be easily confirmed by looking in a Merck
Index. We now know that this type of mercury deposits twice as much inorganic
mercury in the brains of primates as compared to equal doses of methylmercury
(4). Inorganic mercury, following the de-methylation of organic mercury, has
been identified as the primary neurotoxic agent in primate studies (5).
The author mentions the book,
"Evidence of Harm: Mercury in Vaccines and the Autism Epidemic" by David Kirby.
It contains 436 scientific references. The author did not disclose if he read
the book. This may have helped his argument since this book was read by many
parents of autistic children. (4) Burbacher T,

[EOHarm] Ethyl vs. Methyl
THE NATIONAL VACCINE ADVISORY COMMITTEE SPONSORED WORKSHOP ON THIMEROSAL VACCINES

…A second study, which was not discussed this morning, is that adult male and female rats were administered
five daily doses of equimolar concentrations of ethyl
or methylmercury by gavage and tissue distribution,
neurotoxicity, and nephrotoxicity assessed. This was a
Magos study in 1985 in the Archives of Toxicology. And
the key points of that paper were: neurotoxicity of
methyl and ethylmercury were similar, although higher
levels of inorganic mercury were seen in the brains of
ethylmercury-treated rats consistent with what we'd
said about metabolism; and likewise, because of that,
the renal damage was greater in the ethylmercury
treated rats.
…I think it is important to note from the Magos study, in which he directly compared ethyl and methylmercury,
that he found essentially the same results in both
studies, with the exception that the renal toxicity was
greater with ethyl, and I think that was because of the
demethylation as a way of concentrating the mercuric
chloride or inorganic mercury in the kidney.
