The increasing use of tungsten in the production of green energy in the aerospace and military industries, and in many other hi-tech applications, may increase the content of this element in soil. This overview examines some aspects of the behavior of tungsten in soil, such as the importance of characteristics of soils in relation to bioavailability processes, the chemical approaches to evaluate tungsten mobility in the soil environment and the importance of adsorption and desorption processes. Tungsten behavior depends on soil properties of which the most important is soil pH, which determines the solubility and polymerization of tungstate ions and the characteristics of the adsorbing soil surfaces. During the adsorption and desorption of tungsten, iron, and aluminum oxides, and hydroxides play a key role as they are the most important adsorbing surfaces for tungsten. The behavior of tungsten compounds in the soil determines the transfer of this element in plants and therefore in the food chain. Despite the growing importance of tungsten in everyday life, environmental regulations concerning soil do not take this element into consideration. The purpose of this review is also to provide some basic information that could be useful when considering tungsten in environmental legislation.

土壤中钨的动力学:概述

在航空航天和军事工业以及许多其他高科技应用中,越来越多地使用钨生产绿色能源,可能会增加土壤中这种元素的含量。本概述考察了土壤中钨行为的某些方面,例如土壤特征与生物有效性过程相关的重要性、评估土壤环境中钨迁移率的化学方法以及吸附和解吸过程的重要性。钨的行为取决于土壤特性,其中最重要的是土壤 pH 值,它决定了钨酸离子的溶解度和聚合度以及吸附土壤表面的特性。在钨、铁和铝氧化物的吸附和解吸过程中,氢氧化物起着关键作用,因为它们是钨最重要的吸附表面。土壤中钨化合物的行为决定了该元素在植物中以及食物链中的转移。尽管钨在日常生活中的重要性日益增加,但有关土壤的环境法规并未考虑到这一因素。本次审查的目的还在于提供一些在环境立法中考虑钨时可能有用的基本信息。
