  • Toxicity of ethylmercury (and Thimerosal) a comparison with methylmercury.

  • Ethylmercury (sometimes ethyl mercury) is a cation composed of an organic CH3​CH2- species (an ethyl group) bound to a mercury(II) centre, making it a type of organometallic cation, and giving it a chemical formula is C2H5Hg+.

    Ethylmercury is so reactive it does not occur for any measurable amount of time in the environment except under very acidic, rare polluted conditions. Unlike methylmercuryethylmercury may not bioaccumulate but since it decomposes immediately into methyl mercury, that cannot be established under normal conditions. Critical Reviews in Toxicology.
