本文主要讨论粘粒在环境科学中的重要作用,即在土壤粘粒、植物、动物、人及其健康的链中的重要作用。提高农业管理强度,使土壤中某些重要的微量元素贫乏,而加强工业化则使某些环境中一些有害微量元素、有机毒素与放射性元素达到危险的水平。粘粒可吸附并与根系交换离子,因此它是农业、食物与纤维生产的基础。 This article focuses on the important role of clay in environmental science, the important role of clay in soils, plants, animals, humans and their healthy chains. Increasing the intensity of agricultural management will make some important trace elements in the soil poor while strengthening industrialization will put some harmful trace elements, organic toxins and radioactive elements in some environments to dangerous levels. Clumps adsorb and exchange ions with the roots, so it is the basis for agriculture, food and fiber production.
