Acute exposition of developing rats to Methylmercury: a mini-review

Abstract

Mercury (Hg) is present in the environment in three different chemical forms: elemental, inorganic and organic Hg. The distribution, toxicity and metabolism of Hg are linked to its chemical form. The oral exposition following fish and food contaminated is the main route of contamination of humans to the methilmercury (MeHg), an environmental pollutant which is absorbed by ingestion, inhalation and through the skin. MeHg is a strong neurotoxic molecule, especially for the developing brain. In this study, the main effects of the MeHg exposition and the biochemical parameters involved in this process were examined. The results of the use of plant extracts which attenuate the adverse effects of this metal are also presented here. Therefore, these data reinforce the MeHg toxicity during the development and suggest alternative ways for future therapeutic approaches.
