| 摘 要： | 报道了三峡库区长江干流江段鱼体汞元素的含量范围为０．０４￣０．４２ｍｇ／ｋｇ（湿重），高于长江水系鱼体汞含量水平。分析了三峡库区鱼体汞含量高的原因，指出三峡库区毗邻武陵山高汞背景区，主要受汞矿开发、高汞燃煤及城市废弃物排放的影响。利用水库汞活化指数模型，预测三峡水库蓄水后库区干流及４０条主要支流水域汞的活化效应将增强０．３５￣１．５倍，鱼体汞含量将是现在鱼汞含量的１．４￣２．５倍；并根据不同鱼种汞

| Abstract: | Contents of mercury in fish from the main stream of the Changjiang River in Three-Gorgearea are 0. 04 ~ 0. 42 mg/kg, greater than the contents from the Changjiang River water system.Reasons of high mercury in fish in the light of mercury pollution in the Three-Gorge area are discussed. After impounding, mercury reactivity of the reservoir will increase by 0. 4 ~ 1. 5 times,and mercury contents in fish will be 0. 4 ~ 1. 5 times biger than the existing contents, thus therewill be the possibility of fish mercury contents exceeding 0. 3 ppm which is the maximum contentallowed by the Food Hygiene I-aw of the People's Republic of China. |
