东海外陆架及钓鱼岛以北海域鱼类、底栖生物的痕量金属测定

从海洋生物生态学本身的研究,生物体常量,微量元素的测定,前人已作了很多的工作。随着国防、工业及海上交通运输不断高速发展,各种工业废物大量抛入海洋,海洋污染日趋严重。为此,许多海洋学者又从海洋环境保护出发,对各个海域里的生物成分进行了监测,特别对生物体痕量金属的测定已作了大量工作3-6]。测定的范围是广范的,从大洋到极地,从深海到岸边,而对受污染严重的港湾及河口的生物毒物研究得更多。

TRACE METAL CONCENTRATION OF THE FISHES AND BENTHOS FROM THE OUTER CONTINENTAL SHELF ANE THE NORTHERN DIAOYU DAO (TIAOYU ISLAND) OF THE EAST CHINA SEA

This paper describes the application of the technique of inverse polarography (anodic stripping voltammetry) with antiadsorption physical coating mercury electrode,which is convenient and highly sensitive for the determination of seawater,fishes,benthos,and other marine organisms,giving precise and rapid resulis.The technique has an advantage over other methods in that it requires only a small amount of sample and analytical solution.Neither filtration nor the addition of supporting electrolyte is needed.Ashed samples diluted by seawater can be directly used for the determination of Zn,Cd,Pb,and Cu.
