英文摘要 | A series of specific toxicological effects including bioaccumulation of the pollutant, histological changes and influences on cholinesterase (ChE) activities were examined in the adult Japanese medaka after the exposure to graded sublethal concentrations (40, 20, 10, 5, 2.5 ng Hg/mL) of methylmercury chloride (MMC). Methylmercury (MeHg) contents in the exposed medaka tissues ranged from 0.03 to 64.4 mu g Hg/g (wet weight, w.w.). High concentrations of MeHg were accumulated in the liver and brain, while the concentrations in muscle and fat were relatively low. A dose-dependent and exposure time-dependent increase of MeHg contents in tissues was observed. Histopathological changes, such as oedema, vacuolization, pyknotic nucleus, telangiectasis, and degenerative sperm, can clearly be observed in the slices from the liver, gill, and male gonad of the exposed medaka. Inhibition of ChE activity was common in the exposed fish's brain, liver, gill, and muscle. The serious intoxication of MMC to medaka was definitely demonstrated herein.
