methylmercury
methylmercury (ˌmiːθaɪlˈmɜːkjʊrɪ) n (Chemistry) any of various highly toxic organic compounds of mercury that contain the complex CH3Hg-meth•yl•mer•cu•ry (ˌmɛθ əlˈmɜr kyə ri)
n. any of several extremely toxic organometallic compounds, Hg(CH3)2, formed from metallic mercury by the action of microorganisms and capable of entering the food chain: used as seed disinfectants. [1915–20] methylmercury
di·meth·yl·mer·cu·ry (dī-meth'il-mĕr'kyū-rē), A contaminant of seafood products synthesized in sediments from mercury and mercury-containing chemicals dumped in waters supporting marine life. Methylmercury is concentrated in aquatic life forms and can thus be deposited in fish intended for human consumption. Probable cause of Minamata disease, a teratogenic condition characterized by multiple birth defects in Japan. An inorganic reagent.
See also: Minamata disease. Synonym(s): methylmercurymethylmercury An inorganic mercury industrial pollutant. It is concentrated up the food chain, is teratogenic, and causes severe CNS defects in children whose mothers consumed methylmercury-contaminated seafood while pregnant.methylmercury Dimethyl mercury Toxicology An inorganic mercury industrial pollutant; it is concentrated up the food chain, teratogenic and causes severe CNS defects in children whose mothers consumed MM-contaminated seafood while pregnant. See Mercury, Minamata disease. methylmercury, methyl mercury (me-thil-mer'ku-re) An organic mercury compound produced from inorganic mercury by the addition of a methyl group (CH3) by marine and soil bacteria. This compound is readily taken up by plankton, which are then consumed by marine invertebrates, and subsequently by marine predators, in which it concentrates. Finally, it can enter the human body when people eat fish having high concentrations of the compound, such as salmon or halibut (among others). It can also be absorbed into the body through the skin and respiratory tract. Methylmercury is neurotoxic to humans, esp. children. See: mercury poisoningMinamata diseaseAcronymsSeeMeHg |
