Mercury (Hg) & mercury compounds

Heavy metal. In Japan, pesticides including mercury can not use.
Mercury is widespread in the environment since it originates from natural sources, the burning of fossil fuels, industry and the use of fungicides. (ref. ID; 4583)

Toxicity; Methylmercury (MeHg) is a well-documented neurotoxin that poses a danger to the environment and to public health. The human central nervous system is vulnerable to MeHg toxicity, because MeHg, when bound to L-cysteine, can readily traverse the blood-brain barrier. Exposure to high levels of MeHg causes irreversible neurobehavioral and neuropsychological disorders and is particularly detrimental to the brain development of infants and children. (ref. ID; 7172)
