中文摘要：
原生高砷地下水已给人类健康造成了极大威胁。近几十年来，国际上针对高砷地下水已开展了大量的研究Y-作，但由于地下水系统中砷经历的复杂物理、化学及生物地球化学过程，使得地下水系统中砷浓度衰减和运移尚不能进行准确预测。在系统，巷结前人研究工作的基础上，对控制地下水中砷迁移转化的主要物理、化学和生物地球化学过程（包括吸附／解吸、溶解／沉淀、非氧化／还原和生物还原等）进行了系统，总结。重点讨论了孔隙介质中砷的地球化学反应和运移机制的平衡与动态模型，即批反应模型、运移模型、反应运移模型，以期为原生高砷地下水修复及高砷地下水开发指导提供科学依据。
英文摘要：
Native high arsenic groundwater has been a severe threaten to human health all over the world. Numerous studies had been explored to understand the mechanism of arsenic mobilization in the groundwa- ter. However, due to the complicated physical, chemical and biogeochemical processes, the attenuation and transportation of arsenic in groundwater is difficult to predict accurately. Based on the prior resear- ches, this paper summarizes the main physical, geochemical and biogeoehemical processes of the attenua- tion and transportation of arsenic in the groundwater aquifers, including adsorption/desorption, dissolu- tion/precipitation, non-oxidation/reduction, biological reduction, etc. In order to better understand the arsenic mobilization in aquifer systems, this study focuses on discussing the equilibrium model and dynamic model of the geochemical reactions and transportation of arsenic in porous medium, which includes： 1） batch model, 2） transport model, and 3） reactive transport model. The goal of this study is to provide guiding suggestions for the remediation and appropriate exploitation of high arsenic groundwater.
