| 摘 要： | 全球范围内广泛分布的高砷地下水给人们的健康造成了极大的威胁.高砷地下水的形成机理是一项世界性的科学问题.介绍了高砷地下水的分布特点、富集机理,阐明了溶解性有机物、地下水流动特征对高砷地下水形成的影响机制.现今的研究揭示了有机物和微生物协同作用下高砷地下水的形成过程,并且在高砷地下水的空间分布、时间变化特征以及人类活动对高砷地下水形成的影响等方面取得了一些创新性成果.这3方面的研究也逐渐成为近些年高砷地下水研究的热点.这些研究不仅丰富了砷迁移转化的理论成果,而且有助于开辟低砷水源,保障水资源的可持续利用,具有重要的理论和现实意义.

| Abstract: | High-arsenic groundwater widely spreads in the world, which has posed a great threat to human health. Mechanisms of arsenic mobilization in aquifer systems have been considered to be worldwide scientific issues. We outline characteristics of spatial distribution of high-arsenic groundwater and arsenic enrichment mechanisms. Controls of dissolved organic matter and groundwater flow on arsenic mobilization in groundwater are reviewed and discussed. Recent studies reveal synergistic effect of dissolved organic matter and microbial processes on genesis of high arsenic groundwater. Spatial and temporal variations of high arsenic groundwater and anthropogenic activities affecting the high-arsenic groundwater distribution have recently been characterized, and gradually become the hot topics in this field. These aspects are of great significance in enriching our understanding of transportation and transformation in aquifer systems and finding low-arsenic water resources for sustainable water development in arsenic-affected areas. |
