稀土元素（RE）是一组化学性质在不同系列（La ~ Lu）中发生系统变化的微量元素，可作为地球化学示踪剂，用于了解和研究沿海和河口地区的地球化学过程。本文综述了河口水和海水中微量稀土元素的分离、富集和测定方法，以及沿海河口地区稀土元素地球化学研究方法，以及这些地区稀土元素与水、悬浮颗粒物和沉积物之间的相互作用。最后提出了稀土元素地球化学研究的方向和在沿海河口地区开展稀土元素地球化学研究的可能性。
Rare Earth Elements (REEs) which form a coherent group of trace elements whose chemical properties change systematically across the series (La through Lu) are generally used to understand and investigate the geochemical processes of coastal and estuarial areas, which can be employed as geochemical tracer. In this paper, the reviews of separation, pre-concentration, and determination of trace rare earth elements (REEs) in estuarine water and seawater, as well as the approaches of REEs geochemical studies in coastal and estuarial areas and the interactions of REEs between water, suspended particle matter, and sediment in these areas are included. The trend of REEs geochemical research and possible investigation in coastal and estuarial areas are also suggested.
