自1972年发现“二松”水系己被甲基汞污染事实后,从“二松”水系中捕捞的各种江鱼含汞量己有相当危险水平。在人体中己有甲基汞的蓄积,至于微量汞的污染问题报道较少。我室于1978年以汞污染的江鱼对猫进行慢性毒理实验研究,实验证实,猫的小脑己出现慢性“水俣病”——甲基汞中毒的病理改变。 Since the discovery that the “Second Pine” water system had been contaminated with methylmercury in 1972, the mercury content of various river fish caught from the “Second Pine” water system had been at a very dangerous level. There is already methylmercury accumulation in the human body. As for the trace mercury contamination, there are few reports. My laboratory in 1978 to mercury contaminated river fish cat chronic toxicology experiments confirmed that the cat’s cerebellum has chronic “Minamata disease” - methyl mercury poisoning pathological changes.
