首次报道了三峡库区鲤鱼（Ｃｙｐｒｉｎｕｓｃａｒｐｉｏ）、铜鱼（Ｃｏｒｅｉｕｓｈｅｔｅｒｏｄｏｎ）、长吻鱼危（Ｌｅｉｏｃａｓｉｓｌｏｎｇｉｒｓｔｒｉｓ）和翘嘴鱼白（Ｃｕｌｔｅｒａｌｂｕｅｎｕｓ）各组织器官中甲基汞的含量水平，以及地表水甲基汞的浓度。证明鱼体肌肉中甲基含量最高，其次为肝脏、肾脏、脾脏。各组织器官中甲基汞含量与有机汞、无机汞和总贡含量呈显著线性关系；水库鲤鱼甲基汞含量高于河流鲤鱼；三峡库区江段江水甲基汞浓度与加拿大未被污染湖泊湖水相当。 The levels of methylmercury in tissues and organs of Cyprinus carpio, Coreiusheterodon, Leiocasis longirstris and Culteralbuenus in the Three Gorges Reservoir Area for the first time were reported, concentration. Proved fish in the highest methyl content of muscle, followed by liver, kidney, spleen. The content of methylmercury in tissues and organs was linearly correlated with the content of organic mercury, inorganic mercury and the total content of mung bean. The content of methylmercury in carp was higher than that in river carp. The concentration of methylmercury in the river section of Three Gorges Reservoir was similar to that of uncontaminated lakes in Canada The lake is quite.
