自从日本和伊拉克发生汞中毒事件以来,世界各国的卫生工作者对环境汞污染问题进行了大量的研究工作。其中对硒与汞的拮抗作用进行了研究,认为硒对汞有拮抗作用。那么,在探讨汞的毒理学效应时,就不能忽视硒的存在水平。因为渔民的汞中毒主要是食用被汞污染水域的鱼引起的。所以,我们对镜泊湖、长江、珠江水域的鱼进行总汞含量 Since the incident of mercury poisoning in Japan and Iraq, health workers in various countries of the world have conducted a great deal of research on environmental mercury pollution. Among them, the antagonism of selenium and mercury was studied, and selenium was found to have an antagonistic effect on mercury. Well, when discussing the toxicological effects of mercury, the presence of selenium can not be ignored. Mercury poisoning by fishermen is mainly caused by eating fish contaminated with mercury. Therefore, we carry out total mercury content of fish in Jingpohu, Yangtze River and Pearl River waters
