Biogeochemical Processes of Arsenic in Paddy Soils

摘要：

Arsenic (As) is ubiquitous in the environment, and is regarded as class I carcinogen. For populations taking rice as the stable food, rice is the major pathway for human exposure to As. As dynamics in the soil-rice system is therefore critical in risk assessment and reduction for Southeast Asia, where As contamination widely distributes. The aim of this paper is to give an overview of biogeochemical processes in the soil-rice system, with strong focus on how molecular tools (physical, chemical and biological) can be used to unravel the mechanisms of arsenic transport, uptake and metabolism in this system.
