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.
Mercury is extracted from cinnabar by roasting it in air, followed by condensation of the mercury vapour. Mercury is toxic. Poisoning may result from inhalation of the vapour, ingestion of soluble compounds, or absorption of mercury through the skin.
