在鱼贝类体内可高度浓缩甲基汞,而以其为主食的野生海豹的肝、肾中蓄积的汞中有95%以上为无机汞。动物实验时长期给以甲基汞,也发现肝、肾蓄积高浓度的无机汞。无机汞来源考虑为甲基汞脱甲基后形成,故在讨论长期接触甲基汞对机体的影响时,对此必须给以充分的重视。甲基汞在那个脏器,以何种机制进行脱甲基呢?曾利用脏器切片和组织均浆等来进行研究,均未成功。目前仅知肠道内细菌有此作用
Methylmercury is highly concentrated in fish and shellfish, and more than 95% of the mercury accumulated in the liver and kidney of wild seals based on them is inorganic mercury. Long-term animal experiments methylmercury, also found that liver and kidney accumulation of high concentrations of inorganic mercury. Inorganic mercury sources are considered to form methylmercury after demethylation, so in the discussion of long-term exposure to methylmercury on the body, which must be given full attention. Methylmercury in which organs, the mechanism of demethylation it? Have used organ slice and tissue homogenization to carry out the study, were unsuccessful. Currently only know that intestinal bacteria have this effect
