The region selected and the elements analyzed for this study were the same as reported previously. The results obtained can be summarized as the followings. 1) The heavy metals were ordinarily included 2,400-3,100 for Fe, 280-790 for Mn, 8-21 for Co, 13-100 for Cu, 70-700 for Zn, 16-95 for Ni and 1.0-3.9 μg/g of dried matter for Cd. 2) No definite difference was recognized for any metals between the contents of upper layer (0-5 cm from the surface) and those of lowe layer (10-15 cm). 3) The mean quantities of extractable heavy metals in the marine sediments of this district were: 2,000 of Fe, 280 of Mn, 6 of Co, 20 of Cu, 90 of Zn, 6 of Ni and 1 of Cd μg/g of dried matter. 4) The existence of high concentrations of extractable Fe and Mn suggested that the elution of those metals from marine sediments would constantly occur and maintain the long lasting outburst of dinoflagellates, such as Exuviaella sp. and Eutreptiella sp.}, pages = {220--227}, title = {福山周辺海域における底質中の数種重金属の分布について}, volume = {23}, year = {} }
