Elemental and organic methyl/ ethylmercury
can pass undisturbed through the blood-brain barrier and the placenta while inorganic mercury can cause kidney toxicity.
Thimerosal contains ethylmercury
and differs chemically from methylmercury, the form of mercury commonly found in the environment, including some fish.
2+]) and the ethylmercury
derivative thimerosal potently blocked IGF-1 stimulation of MS and reduced basal activity to very low or undetectable levels.
Methylmercuy was metabolized 10 times slower than ethylmercury
, and between vaccinations, the mercury in ethylmercury
It is simply assumed that ethylmercury
is not as dangerous as methylmercury because it is metabolized more quickly.
Thimerosal is broken down in the body to thiosalicylate and ethylmercury
6 mercury by weight and is metabolized into ethylmercury
and thiosalicylate" (Price et al.
60) Thimerosal is an ethylmercury
compound that has been used as a preservative in vaccines since the 1930s.
One of its metabolites, ethylmercury
, does not accumulate in the body or in the brain but is metabolized and cleared from the organism (Miller & Reynolds, 2009).
Aposhian also offered testimony seeming to support a theory of "genetic hypersusceptibility," which means that some individuals may be genetically predisposed to immune system damage from ethylmercury
6 percent elemental mercury by weight and is metabolized or degraded into ethylmercury
The paper by Geier et al (1) addresses the plausible association of premature puberty after a typical pattern of exposure to ethylmercury
in thimerosal-containing vaccines (TCVs) taken by young children in the USA before TCVs were discontinued.
