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.
