Abstract

Chronic exposure to geogenic contaminated groundwaters (GCGs) has caused serious health problems among billions of people worldwide. The hydrogeological features, main sources of geogenic hazardous substances, dominant hydrogeochemical processes and key factors controlling the occurrence of high arsenic (As ≥ 10 μg/L), high fluoride (F ≥ 1 mg/L), and high iodine (I ≥ 100 μg/L) groundwater are discussed in this review. Although the global and/or regional occurrence, and the environmental and geochemical behaviors of groundwater As, F and I have been well documented in the past three decades, there is still a lack of holistic theoretical analysis to demonstrate the hydrogeological patterns of their (co)occurrence. We here propose four basic genetic types of GCGs by summarizing the characteristics of the distribution and major hydrogeochemical processes: leaching-enrichment type, burial-dissolution type, compaction-release type, and evaporation-concentration type. The complex genetic mechanisms of GCGs are thus integrated into a new theoretical framework to improve our understanding of their genesis and our capability of predicting their spatial and temporal distribution. Moreover, new paradigms of interdisciplinary convergent research are required to find best solutions to ensure the sustainable safe supply of groundwater resources and the well-being of the groundwater-dependent ecosystems and the human society.

地质污染地下水的成因:As、F和I

摘要

长期暴露于受地质污染的地下水 (GCG) 已在全球数十亿人中造成严重的健康问题。水文地质特征、成因有害物质主要来源、主要水文地球化学过程及控制高砷(As≥10μg/L)、高氟(F≥1mg/L)、高碘(I≥100)发生的关键因素μg/L) 地下水在本综述中进行了讨论。尽管在过去的 30 年中,地下水 As、F 和 I 的全球和/或区域发生情况以及环境和地球化学行为已经得到了很好的记录,但仍然缺乏整体的理论分析来证明其(co)的水文地质模式。 )发生。我们在此通过总结分布特征和主要水文地球化学过程的特征,提出了四种基本的 GCG 成因类型:浸出富集型、埋藏溶解型、压实释放型和蒸发浓缩型。因此,将 GCG 的复杂遗传机制整合到一个新的理论框架中,以提高我们对其起源的理解以及预测其时空分布的能力。此外,需要跨学科融合研究的新范式,以找到最佳解决方案,以确保地下水资源的可持续安全供应以及依赖地下水的生态系统和人类社会的福祉。因此,将 GCG 的复杂遗传机制整合到一个新的理论框架中,以提高我们对其起源的理解以及预测其时空分布的能力。此外,需要跨学科融合研究的新范式,以找到最佳解决方案,以确保地下水资源的可持续安全供应以及依赖地下水的生态系统和人类社会的福祉。因此,将 GCG 的复杂遗传机制整合到一个新的理论框架中,以提高我们对其起源的理解以及预测其时空分布的能力。此外,需要跨学科融合研究的新范式,以找到最佳解决方案,以确保地下水资源的可持续安全供应以及依赖地下水的生态系统和人类社会的福祉。
