메틸수은 C화학적 특성, 용도, 생산
개요
Much of the notoriety of methylmercury has been generated
from three separate mass poisoning events, two in Japan and
one in Iraq. These events, at Minamata Bay in Niigata prefecture,
and in Basra, demonstrated the potential lethality of
methylmercury after it was a known toxic substance, and,
though mercury is still an important risk factor for developmental
toxicity, since the 1970s there have not been any
large-scale poisonings of this type. Methylmercury is formed
naturally in aquatic environments through the action of
anaerobic bacteria on inorganic mercury.
화학적 성질
Water soluble, lipid soluble, high vaporpressure.
용도
Organomercury compounds such as aryl and alkoxy-aryl have
been used in medicine, agriculture, and laboratory research.
Their use in medicine and in fungicides has been greatly
reduced or eliminated.
정의
Either of two com-pounds that contain the methyl group and commonsalts of monomethylmercury.
위험도
Mutagen; possible carcinogen; teratogen;central nervous system poisons that easily passthrough the blood–brain barrier.
Safety Profile
A poison. An
experimental teratogen. Experimental
reproductive effects. Mutation data
reported. Used as a fungicide. When heated
to decomposition it emits toxic fumes of
Hg.
잠재적 노출
Methyl mercury has been
used as seed disinfectants and for fungicides. It has
also been used in organic synthesis.
환경귀착
Inorganicmercury introduced as a pollutant into natural waters is
scavenged by particulate matter and deposited into bottom
sediments. Free Hg2+ is gradually released from this pool of
slightly soluble inorganic mercury and is then transformed by
microbial activity into methylmercury. Methylmercury diffuses
into thewater column and is takenupbyfishand other organisms
(either directly through water or through the food chain), and
accumulated in their tissue. The degree to which mercury is
transformed into methylmercury and transferred up the food
chain through bioaccumulation depends on a variety of factors,
including water chemistry and the complexity of the food web.
