The kind of mercury that accumulates to toxic levels in fish is called monomethylmercury, or simply methylmercury, because it has a methyl group, CH3, attached to the mercury atom. The problem is that we donât know where methylmercury comes from.
Elemental mercury is a heavy, silver-white liquid metal that can be found at trace levels in many minerals with greater concentrations in fossil fuels. There are three forms of mercury in the environment: elemental, inorganic, and organic mercury.All forms of mercury are toxic.www.epa.state.oh.us/opp/ pq/fall98/merc498.html. Elemental mercury occurs naturally in three valence states: elemental (Hg0), monovalent-mercurous (Hg1+), and the divalent mercuric (Hg2+).Elemental mercury is the most stable form and is only slightly water-soluble.here are three forms of mercury in the environment: elemental, inorganic, and organic mercury.
