| contents | Distribution of Cd and Pb in sea ice and in under-ice water of the Amur Bay at the end of February 1998 is considered. The metals were determined by technique of inversion voltammetry. Contribution of Cd and Pb from atmospheric precipitation and from under-ice water to sea ice examined is discussed. On the basis of analysis of vertical distribution in ice, atmospheric fluxes supplying metals to the aquatic area of the bay are estimated at 100 and 2000 µg/m**2/year for Cd and Pb, respectively. Concentrations of Cd and Pb found in middle and lower parts of ice cores allow to suggest that their accumulation relative to main ions of seawater occurs in the ice. Estimated enrichment factors of Cd and Pb in sea ice relative to seawate are ~9 and ~5. A possible mechanism of relative metal accumulation in sea ice is considered. |
