Journal ArticleDOI
Arsenic poisoning of Bangladesh groundwater
TL;DR: Sedimentological study of the Ganges alluvial sediments shows that the arsenic derives from the reductive dissolution of arsenic-rich iron oxyhydroxides, which in turn are derived from weathering of base-metal sulphides.
Journal ArticleDOI
Mechanism of arsenic release to groundwater, Bangladesh and West Bengal
TL;DR: In some areas of Bangladesh and West Bengal, concentrations of As in groundwater exceed guide concentrations, set internationally and nationally at 10 to 50 m gl ˇ1 and may reach levels in the mg l ˆ 1 range.
Journal ArticleDOI
Decoupling of As and Fe release to Bangladesh groundwater under reducing conditions. Part I: Evidence from sediment profiles
A. Horneman,A. Horneman,A. van Geen,Dennis V. Kent,Dennis V. Kent,Pierre-Etienne Mathé,Yan Zheng,Yan Zheng,R.K. Dhar,Suzanne O'Connell,Mohammad A. Hoque,Z. Aziz,Z. Aziz,Mohammad Shamsudduha,A. A. Seddique,Kazi Matin Ahmed +15 more
TL;DR: In this article, the authors re-examine the notion that extensive As mobilization in anoxic groundwater of Bangladesh is intimately linked to the dissolution of Fe oxyhydroxides on the basis of analyses performed on a suite of freshly collected samples of aquifer material.
Journal ArticleDOI
Redox control of arsenic mobilization in Bangladesh groundwater
Yan Zheng,Yan Zheng,Martin Stute,Martin Stute,A. van Geen,Ittai Gavrieli,R.K. Dhar,H. J. Simpson,H. J. Simpson,Peter Schlosser,Peter Schlosser,Kazi Matin Ahmed +11 more
TL;DR: In this article, the authors examined redox processes that lead to As mobilization in groundwater, and deduced from isotopic signatures of δ34SSO4 and 3H2O (3H) to delineate the nature of redox changes for some of the reducing groundwaters.
Journal ArticleDOI
Spatial variability of arsenic in 6000 tube wells in a 25 km2 area of Bangladesh

TL;DR: The proportion of wells that exceed the Bangladesh standard for drinking water of 50 μg/L arsenic increases with depth from 25% between 8 and 10 m to 75% between 15 and 30 m, then declines gradually to less than 10% at 90 m as mentioned in this paper.
