西北冰洋沉积物中重金属的研究

本文利用我国首次和第2次北极科学考察航次获得的沉积物样品,对楚科奇海、波弗特海及加拿大海盆海域30站表层样和4个短岩芯,进行了Cu、Zn、Pb、Cd、Cr五种重金属元素的总量分析和形态分析,以了解其平面分布和垂直分布特征。主要结果如下: (1)在表层沉积物中,Cu的含量范围为7.07μg/g~51.30μg/g,均值为26.83μg/g。Zn的含量介于33μg/g~141μg/g,均值为96μg/g。Pb的含量介于9.1μg/g~31.8μg/g,均值为20.9μg/g。Cd的含量介于0.069μg/g~0.362μg/g,均值为0.153μg/g。Cr的含量介于42.3μg/g~113μg....

Summary:本文利用我国首次和第2次北极科学考察航次获得的沉积物样品,对楚科奇海、波弗特海及加拿大海盆海域30站表层样和4个短岩芯,进行了Cu、Zn、Pb、Cd、Cr五种重金属元素的总量分析和形态分析,以了解其平面分布和垂直分布特征。主要结果如下: (1)在表层沉积物中,Cu的含量范围为7.07μg/g~51.30μg/g,均值为26.83μg/g。Zn的含量介于33μg/g~141μg/g,均值为96μg/g。Pb的含量介于9.1μg/g~31.8μg/g,均值为20.9μg/g。Cd的含量介于0.069μg/g~0.362μg/g,均值为0.153μg/g。Cr的含量介于42.3μg/g~113μg. Basing on the First and Second Chinese National Arctic Expedition cruises, the bulk contents and speciations of heavy metals were analyzed in the total 30 surface sediments and 4 sediment cores, which were taken in the western Arctic Ocean. The contents of Cu、Zn、Pb、Cd、Cr and their speciations were analyzed for probing into the distribution and vertical distribution in the Western Artic Ocean .The . 学位:理学硕士 院系专业:海洋与环境学院海洋学系_海洋化学 学号:22420071150859
