This lecture explores the geogenic contaminant arsenic in the SE Asia delta, focusing on speciation, organic species, and their toxicity. It discusses the essential role of IRB and SRB in rice uptake and arsenic mobility, as well as the formation of thio-arsenic species. The impact of excess pumping on groundwater arsenic contamination is analyzed, along with filtration methods for arsenic removal. Human exposure risks, arsenicosis symptoms, and affected areas in SE Asia are also covered, emphasizing the importance of understanding microbial transformations of arsenic for water quality management.
