The presence of elevated concentration of arsenic (As) in natural hydrologic systems is regarded as the most formidable environmental crisis in the contemporary world. With its substantial presence in the drinking water of more than thirty countries worldwide, and with an affected population of more than 100 million, it has been termed as the largest mass poisoning in human history. In this special issue, we have tried to provide the most recent research advances on controls and challenges of this severe groundwater contaminant. The articles in this issue, originally presented in the 2006 Geological Society of America Annual Meeting, address the distribution of As in various geologic and geographic settings, the controls of redox and other geochemical parameters on its spatial and temporal variability, the influence of sedimentology and stratigraphy on its occurrence, and mechanisms controlling its mobility. The knowledge available from these studies should provide a roadmap for future research in arsenic contamination hydrology.
自然水文系统中高浓度砷(As)的存在被视为当代世界最严峻的环境危机。全球三十多个国家的饮用水中都大量存在砷,受影响人口超过1亿,这被称为人类历史上最大规模的中毒事件。在本期特刊中,我们试图呈现关于这种严重地下水污染物的控制措施和挑战的最新研究进展。本期的文章最初发表于2006年美国地质学会年会上,探讨了砷在各种地质和地理环境中的分布、氧化还原及其他地球化学参数对其时空变化的控制、沉积学和地层学对其赋存的影响,以及控制其迁移性的机制。这些研究所得出的知识应为未来砷污染水文研究提供路线图。
