A child abuse fatality occurs when a child's death is the result of abuse or neglect, or when abuse and/or neglect are contributing factors to a child's death. In the United States, 1,730 children died in 2008 due to factors related to abuse; this is a rate of 2 per 100,000 U.S. children.
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 does cause damage by blocking blood vessels. Mercury's zero oxidation state Hg 0 exists as vapor or as liquid metal, its mercurous state Hg + exists as inorganic salts, and its mercuric state Hg 2+ may form either inorganic salts or organomercury compounds; the three groups vary in effects.ercury poisoning can be prevented (or minimized) by eliminating or reducing exposure to mercury and mercury compounds. To that end, many governments and private groups have made efforts to regulate heavily the use of mercury, or to issue advisories about its use.
