Important human exposure sources are mercury vapors inhaled after release from dental amalgam, methyl mercury (MeHg) from fish and
ethyl mercury (EtHg) present in vaccines and some pharmaceutical products (Barregard et al., 2011; Risher et al., 2002; Clarkson and Magos, 2006; Ishitobi et al., 2010).
The kind found in vaccines is
ethyl mercury, and this is water-soluble and rapidly metabolized in the body so they do not accumulate, he said.
Thimerosol is an antiseptic containing 49.5%
ethyl mercury that has been used for years as a preservative in many infant vaccines and in flu vaccines.
The
ethyl mercury is from sodium ethylmercyrithosalicylate (thimerosal) used in vaccines and eye drops as preservative.
No wonder the concentration of
ethyl mercury increase with trophic level and age.
Thimerosal contains
ethyl mercury, which is different from the methyl mercury that we all remember as the silvery liquid substance found in old thermometers.
A typical growth, abnormal mitosis and polyploidy induced by
ethyl mercury chloride.
Thimerosal contains a small amount of
ethyl mercury.
Thimerosal, the vaccine preservative, contains
ethyl mercury, and most of the toxicological data is on methyl mercury.
Compared with the blood half-life of about 45 days associated with methylmercury from fish consumption, the half-life of intramuscular
ethyl mercury from thimerosal in vaccines in infants is substantially shorter, at a mean of 3.7 days with a return to baseline by 30 days post vaccination (Pediatrics 2008;121:e208-14).
Infants excrete the
ethyl mercury used in thimerosal-containing vaccines too quickly for the mercury to build up in their systems, according to study results.
Thimerosal is a vaccine preservative, and is partially composed of
ethyl mercury. In 1999, there was a decision to reduce or eliminate thimerosal from pediatric vaccines manufactured for the U.S.
