【摘要】 <正> 自从日本发生两次“水俣病”以来,环境中汞的含量日益引起人们的注意和重视。近年来,许多学者对测定水生生物体内汞的积累量及其与环境之间的相互关系等方面的研究,进行了大量工作。Thommes等(1972)测定了美国的伊利湖、密执安湖和苏必利湖中四种鱼体内汞的含量。Anderson等(1974)测定了挪威、奥斯陆湾14个不同区域中6种更多还原

【Abstract】 Mercury content in 20 samples of marine organisms was determined by cold vapour atomic absorption method. The samples determined include 5 species of fishes, 3 species of Mollusks, 4 species of Crustaceans, 4 species of Echinoderms and 4 species of Coele-mterates.The results obtained are summarized as follows;1. Mercury level in fish is the highest among the samples determined.2. Mercury content in fish is relevant to the depth where they live, It increases with increasing depth.3. The muscle, liver, gill, skin and spawn of Cypselurne pociloplerws were analyzed for mercury content. It was found that liver has the highest among these tissues.4. The concentration factor of mercury by fish from sea waster is about 2,000.更多还原
