ethylmercury in fish

According to the FDA, “a vaccine containing 0.01% thimerosal as a preservative contains… roughly the same amount of elemental mercury contained in a 3 ounce can of tuna fish.” Ethylmercury is water soluble, so your body excretes it. ... This prevents ethylmercury from building up to harmful levels in your body.

Is Ethylmercury harmful?

Human exposure is mostly due to ingestion of contaminated fish. Ethylmercury (EtHg), another organic mercury compound, has received significant toxicological attention due to its presence in thimerosal-containing vaccines.

Does Ethylmercury accumulate in the body?

The half-life of ethyl mercury is short (less than one week) compared to methyl mercury (1.5 months) making exposure to ethyl mercury in blood comparatively brief. Further, ethyl mercury is actively excreted via the gut unlike methyl mercury that accumulates in the body.

Is Ethylmercury organic?

Ethylmercury (sometimes ethyl mercury) is a cation composed of an organic CH3CH2- species (an ethyl group) bound to a mercury(II) centre, making it a type of organometallic cation, and giving it a chemical formula C2H5Hg+. The main source of ethylmercury is thimerosal.

What Fish is high in methylmercury?

Nearly all fish and shellfish contain traces of methylmercury. However, larger fish that have lived longer have the highest levels of methylmercury because they've had more time to accumulate it. These large fish (swordfish, shark, king mackerel and tilefish) pose the greatest risk.

Does Ethylmercury cross the blood brain barrier?

The evidence indicates that ethylmercury (C2H5Hg+) -containing compounds do cross the blood-brain barrier (BBB).

Is thimerosal poisonous?

Thimerosal is a mercury-containing preservative used in some vaccines and other products since the 1930s. No harmful effects have been reported from thimerosal at doses used in vaccines, except for minor reactions, such as redness and swelling at the injection site.

What drugs contain thimerosal?

Thimerosal as a preservative is present in certain other vaccines. Examples are tetanus toxoid, Td, DT, certain formulations of influenza vaccine, and meningococcal polysaccharide vaccine in multidose vials.

Can Mercury pass the blood brain barrier?

Elemental (metallic) mercury: shiny, silver, odorless liquid used in thermometers. It is absorbed by the body through vapors. ... These forms of mercury are soluble in lipids and cross the blood brain barrier and placenta easily. Organic mercury is absorbed through the digestive tract and also through vapors.

Is thimerosal still used?

Thimerosal hasn't been used in vaccines for children since 2001. However, thimerosal is still used in some flu vaccines. Yearly flu vaccines are recommended for all children. If you are worried about thimerosal, you can ask for a flu vaccine without it.

Do flu vaccines have mercury in them?

WHAT THE EVIDENCE SAYS: Currently available flu vaccines are aluminum-free and over 80% of flu vaccines today contain no mercury at all. Some flu vaccines contain a tiny amount of formaldehyde that is less than 1% of the amount naturally found in people and is safely cleared from the body.

What is the difference between methylmercury and ethylmercury?

Ethylmercury is broken down and excreted much more rapidly than methylmercury. Therefore, ethylmercury (the type of mercury in the influenza vaccine) is much less likely than methylmercury (the type of mercury in the environment) to accumulate in the body and cause harm.

What foods contain thimerosal?

Here are eight foods you should avoid to reduce your exposure to dietary mercury.
