摘要/Abstract

摘要： 湖泊沉积物不仅记载着积水区域环境质量的历史变化,而且反映出沉积过程的环境条件和沉积物质的地球化学行为。瑞士Greifcn湖是一个受人为活动强烈干扰的富营养湖泊,其下层滞水带季节性缺氧。

Abstract: Comparing the radionuclide inventories of sediment (⁹⁰Sr,¹³⁷Cs,^230,240Pu,^2,0Pb_ex,⁷Be) with the inventories expected from atmospheric fallout records, we find that the ratios are between 0.38-1.3 in the sediment core GR-83-11 of Lake Greifen. On the basis of the erosion in drainage basin and of the retention in laker a model is made from measured quantities to predict the radionuclide inventory ratio in this paper. The best agreements between calculated and observed inventories were obtained for the nuclides. For the calculated error. we would easily be explained by different mechanism of additional removal for individual nuclide.
