Journal ArticleDOI
Role of metal-reducing bacteria in arsenic release from Bengal delta sediments
Farhana Islam,Andrew G. Gault,Christopher Boothman,David A. Polya,John M. Charnock,John M. Charnock,Debashis Chatterjee,Jonathan R. Lloyd +7 more
TL;DR: It is shown that anaerobic metal-reducing bacteria can play a key role in the mobilization of arsenic in sediments collected from a contaminated aquifer in West Bengal and that, for the sediments in this study, arsenic release took place after Fe(iii) reduction, rather than occurring simultaneously.
Journal ArticleDOI
Arsenic Sequestration in Iron Plaque, Its Accumulation and Speciation in Mature Rice Plants (Oryza Sativa L.)
Wang-Rong Liu,Yong-Guan Zhu,Yan-Yu Hu,Paul N. Williams,Andrew G. Gault,Andrew A. Meharg,John M. Charnock,F. A. Smith +7 more
TL;DR: There was significant variation in iron plaque formation between genotypes, and the distribution of arsenic in different components of mature rice plants followed the following order: iron plaque > root > straw > husk > grain for all genotypes.
Journal ArticleDOI
The control of organic matter on microbially mediated iron reduction and arsenic release in shallow alluvial aquifers, Cambodia
H. A. L. Rowland,R. L. Pederick,David A. Polya,Richard D. Pancost,B. E. van Dongen,Andrew G. Gault,David J. Vaughan,Charlotte Bryant,B. Anderson,Jonathan R. Lloyd +9 more
TL;DR: In this paper, microcosm experiments using Cambodian sediments (which are also representative of other similar reducing aquifers containing arsenic-rich waters) show that arsenic release and iron reduction are microbially mediated.
Journal ArticleDOI
Arsenic hazard in shallow Cambodian groundwaters
David A. Polya,Andrew G. Gault,N. Diebe,P. Feldman,J. W. Rosenboom,E. Gilligan,D. Fredericks,Abul Hasnat Milton,Mickey L. Sampson,H. A L Rowland,H. A L Rowland,P. R. Lythgoe,J. C. Jones,C. Middleton,D. A. Cooke +14 more
TL;DR: In this article, small-scale hazard maps for arsenic in shallow Cambodian groundwaters based on >1000 groundwater samples analysed in the Manchester Analytical Geochemistry Unit and elsewhere are presented.
Journal ArticleDOI
XAS and XMCD evidence for species-dependent partitioning of arsenic during microbial reduction of ferrihydrite to magnetite.
V. S. Coker,Andrew G. Gault,Carolyn I. Pearce,G. van der Laan,Neil D. Telling,John M. Charnock,David A. Polya,Jonathan R. Lloyd +7 more
TL;DR: In both experiments, no increase in dissolved As was observed during reduction to magnetite (complete upon 5 days incubation), consistent with earlier observation of As sequestration by the formation of biogenic Fe(III)-bearing minerals.
