Abstract

Considering the increasing sediment content and increasing sediment flux of the Yellow River over the years, it is of significance to investigate the potential interfacial force mechanism between pollutants and Yellow River sediment. This article has reviewed the current research on the Yellow River sediments' mineral structures while investigating the potential interaction force between sediment and pollutants in the water environment. This article has conducted a comprehensive analysis of the influence of sediment on the migration of pollutants in the water environment. What is more, the authors have provided an outlook on the future applications of sediment in ecological environmental systems. Yellow River sediment mainly included minerals and some clay phases, while its irregular surface provided sites for the interface adsorption of pollutants. The interface force between the sediment and pollutants is mainly attributed to promoting bacterial growth on the surface of sediments, physisorption, and chemisorption forces. The sediments carry and transport pollutants during the long-distance water flow migration process. The sediment should be effectively utilized and better integrated into ecological or environmental restoration systems. This article provides a reference for studying the behavior of Yellow River sediment and the direction of future efficient utilization.

黄河泥沙在污染物界面迁移和归宿中的关键作用及环境泥沙修复应用前景评述》。

考虑到多年来黄河泥沙含量的不断增加和泥沙通量的不断增大，研究污染物与黄河泥沙之间潜在的界面作用力机制具有重要意义。本文在研究水环境中泥沙与污染物之间潜在作用力的同时，对黄河泥沙矿物结构的研究现状进行了综述。本文全面分析了泥沙对污染物在水环境中迁移的影响。此外，作者还对泥沙在生态环境系统中的未来应用进行了展望。黄河泥沙主要包括矿物和一些粘土相，其不规则的表面为污染物的界面吸附提供了场所。沉积物与污染物之间的界面力主要归因于促进沉积物表面细菌生长、物理吸附力和化学吸附力。在水流长距离迁移过程中，沉积物会携带和迁移污染物。沉积物应得到有效利用，并更好地融入生态或环境修复系统。本文为研究黄河泥沙的行为和未来有效利用的方向提供了参考。

期刊介绍： The Journal accepts papers describing work that furthers our understanding of the exposure, effects, and risks of chemicals and materials in humans and the natural environment as well as approaches to assess and/or manage the toxicological and ecotoxicological risks of chemicals and materials. The journal covers a wide range of toxic substances, including metals, pesticides, pharmaceuticals, biocides, nanomaterials, and polymers such as micro- and mesoplastics. Toxics accepts papers covering: The occurrence, transport, and fate of chemicals and materials in different systems (e.g., food, air, water, soil); Exposure of humans and the environment to toxic chemicals and materials as well as modelling and experimental approaches for characterizing the exposure in, e.g., water, air, soil, food, and consumer products; Uptake, metabolism, and effects of chemicals and materials in a wide range of systems including in-vitro toxicological assays, aquatic and terrestrial organisms and ecosystems, model mammalian systems, and humans; Approaches to assess the risks of chemicals and materials to humans and the environment; Methodologies to eliminate or reduce the exposure of humans and the environment to toxic chemicals and materials.
