Abstract

Patterns of the distribution of rare earth elements (REEs) in natural objects are important geochemical indicators of the state of the environment. Data on the REE contents in fucus algae from different horizons of the littoral of the Barents Sea are presented for the first time. The behavior of REEs in natural processes is controlled by the solubility of their compounds, their capability of complex formation, and the tetrad-effect of fractionation. Natural factors determining REE migration in the sediment–water–macrophytes system are discussed.

巴伦支海墨角藻中的稀土元素

摘要

自然物体中稀土元素（REE）的分布模式是环境状况的重要地球化学指标。首次提供巴伦支海沿岸不同层位墨角藻中稀土元素含量的数据。稀土元素在自然过程中的行为受其化合物的溶解度、复合物形成能力以及分馏的四分体效应控制。讨论了决定沉积物-水-大型植物系统中稀土元素迁移的自然因素。
