Inorganic mercury is corrosive characteristics should have direct effects on mucosal burns. The rate of absorption through the gastrointestinal tract is only 10% of the amount ingested, mercury accumulated in the kidneys causing kidney damage. Although poorly soluble in fat but if exposed for a long time, Mercury also accumulates gradually in the brain, cerebellum and cerebral cortex lesions cause central nervous system. Lethal dose of inorganic mercury is 1 - 4 g in adults.
Mercury Organic absorbed through inhalation, ingestion and through the skin. Absorption in the gastrointestinal tract, who 90%, less for long strings. Toxicity of organic mercury usually happens with short alkyl chains, particularly methyl mercury. Swallowing 10 - 60 mg / kg sufficient fatal, and swallow small amounts in a long time, just the amount of 10μg / kg sufficient harm to the nervous system and fertility of adults. Because fat-soluble organic mercury so quickly on the color distribution throughout the body, accumulates in the brain, kidney, liver, skin and hair. Obvious toxic effects first and most dangerous in the brain.
Mercury combined and inactivated causes degeneration of neurons in the cerebral cortex and cerebellum, leading to symptoms of paralysis, ataxia, deafness, shrinking market bare. This substance over each other easily and concentrate in severe fetal toxicity to the fetus. The half-life of mercury in adults is 40-50 days, mainly excreted in the feces (90%) and urine. Thus on the human body, not only mercury but also highly toxic persistent lasting harm. Be explained due to the biological characteristics of Mercury is (1) the ability to incorporate, culling slow and incomplete. (2) highly concentrated, high accumulation and (3) to amplify the biological effects on the human body. Particularly for children, especially the fetus and young children are very sensitive to the toxic effects of mercury. When compared to adults, this shows more sensitivity than 10-15 times, so that mercury poisoning in children are consequences more severe brain damage and irreversible.
