内容記述 The distribution of heavy metals (Zn, Cd, Cu, Fe, Mn, Co, Ni and Pb) was investigated in surface sediment samples from Naha port, Tomari port and Nakagusuku bay in Okinawa Island. The total metal concentrations were in the range of Mn (155 -1840 mg/kg), Zn (86 - 2910 mg/kg), Pb (29- 460 mg/kg), Cu (0-945 mg/kg), Co (14 - 204 mg/kg), Ni (0-240\nmg/kg) cd (0-2 mg/kg) and Fe (9650-11400 mg/kg). A sequential extraction procedure was carried out on the sediment samples to determine the chemical state of heavy metals in the sediments. All the elements analyzed except Cd were detected in several to 10% in the exchangeable fraction. Metals such as Zn, Pb and Co showed appreciable concentration in the carbonate fraction where they represented between 16-50 % of the total. In the reducible fraction most metals were found in appreciable percentages where Pb represented 36% of the total. In the oxidizable fraction, Cu, Mn, Co, Fe and Zn represented between 10-40% of the total while Ni and Pb represented less than 10%. The residual/ silicate fraction was the most abundant pool for most metals analyzed like Fe, Mn, Ni and Cd. The present results are indicative of the contribution of heavy metal pollution in the marine environments of Okinawa Island.
