Some of the results about vertical profile of heavy metals of seawater to the south of Japan in Oct.1990 are presented and discussed in relation to the concentration of dissolved Cu, Cd and Ni to biogeochemical environments.It points out that the distribution of dissolved Cu is higher in surface water than that in/upper 500 m layer, and maxima value attains the 8.2 n mol/dm3 in depth of 4 000 m.The concentrations of dissolved Ni ranges from 3.4 n mol/dm3 in surface seawater to 8.5 n mol/dm3 in the deep to the south of Japan.The highest values are observed in the colder waters.This paper shows also that the vertical profile of dissolved Cd is perfect nutrient-type distribution.And dissolved Cd and Phosphate are linearly correlated by the regression equation.The △Cd:△N:△P atomic ratio is 3.5×10-4:14:1.
