【 摘 要 】

Methylmercury is the most hazardous mercury species known. Due to its high stability, lipid solubility, and ionic properties, this compound shows a high ability to cross membranes in living organisms, damaging the central nervous system, mainly the brain, and the effects of chronic poisoning are progressive. In this paper some aspects related to the toxicity and the cases of methylmercury poisoning are described. Other aspects related to the behavior of methylmercury and the environmental factors that influence the transformation of mercury in the water and sediment, with emphasis on the methylation/demethylation reactions and the mercury cycle are discussed.
