摘要
通过对比福建省各个河口、海湾沉积物与其物源区水系沉积物元素含量,发现微量元素在浅海环境中的富集系数■(Ni)>■(Cr)>■(As)>■(Cu)>■(Zn)>■(Pb)>■(Hg)>■(Cd),揭示各元素的迁移机制有所不同;有些区域富集系数偏离平均值较多,反映出有些元素有额外的输入,最有可能是人为污染的叠加。
Based on a comparative study of the element content of stream sediments in various river months, gulfs and their provenances, the authors found that the enrichment coefficients of trace elements in the shallow sea environment have the variation regularity of K（Ni） 〉K（Cr） 〉K（As） 〉K（Cu） 〉K（Zn） 〉K（Pb） 〉K（Hg） 〉K（Cd）, suggesting that the migration mechanisms of various elements are somewhat different from each other. The regional enrichment coefficients of some elements deviate remarkably from their average values, implying that some elements have experienced additional input, most probably caused by the superposition of human pollution.
