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
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.
