Abstract

This overview presents the updated physicochemical characteristics of thallium and its stable isotopes (205Tl/203Tl) in the context of their occurrence and fate in abiotic and biotic systems. This also deals with the thallium behavior in geochemical interactions in and between different environmental compartments and describes its natural (geogenic) and industrial sources. The particular emphasis is placed on some extreme environments, including acid mine drainage areas where oxidation processes of Tl-bearing pyrite and other sulfides lead to very high concentrations of this metal in reactive acidic waters. Many geochemical studies have also employed stable thallium isotopes to reconstruct redox conditions in different environmental systems, to fingerprint relative pollution source strengths and to evaluate mobility of this element and its geochemical interactions in the mineral-water and soil–plant systems. This is the reason why this overview also highlights the growing potential of stable Tl isotopes in solving different geologic and environmental issues.

环境中and及其稳定同位素的丰度和归宿

摘要

本概述介绍了and及其稳定同位素(205 Tl / 203Tl)在非生物和生物系统中的发生和命运的背景下。这也涉及al在不同环境区域之间及其之间的地球化学相互作用中的行为,并描述了其天然(地质)和工业来源。特别强调的是某些极端环境,包括酸性矿山排水区,在这些酸性区中,含T1的黄铁矿和其他硫化物的氧化过程会在反应性酸性水中导致这种金属的浓度很高。许多地球化学研究还采用了稳定的al同位素来重构不同环境系统中的氧化还原条件,以指纹图谱相对污染源的强度,并评估该元素的迁移率及其在矿泉水和土壤-植物系统中的地球化学相互作用。
