Associations between inorganic arsenic in rice and groundwater arsenic in the Mekong Delta
Rizlan Bernier-Latmani, Matthew Charles Reid
There is growing concern regarding human dietary exposure to arsenic (As) via consumption of rice. The concentration and speciation of As in rice are highly variable, and models describing rice As speciation as a function of environmental covariates remain ...
2021Variability in arsenic methylation efficiency across aerobic and anaerobic microorganisms
Rizlan Bernier-Latmani, Karin Lederballe Meibom, Karen Elda Viacava Romo, Arnaud Michel Gelb, Leia Soraya Véronique Falquet, Shannon Eliot Dyer, Adrien Mestrot
Microbially-mediated methylation of arsenic (As) plays an important role in the As biogeochemical cycle, particularly in rice paddy soils where methylated As, generated microbially, is translocated into rice grains. The presence of the arsenite (As(III)) m ...
2020Methylation of arsenic by single-species and soil-derived microbial cultures
Arsenic (As) is simultaneously a ubiquitous and a toxic element. Arsenic is subject to bio-transformations catalyzed by microorganisms constituting the As biogeochemical cycle. The primordial Earth was devoid of oxygen, exposing life to the highly mobile a ...
EPFL2020Arsenic methylation dynamics in a rice paddy soil anaerobic enrichment culture
Rizlan Bernier-Latmani, Julien Maillard, Alexandre Bagnoud, Leia Soraya Véronique Falquet, Matthew Charles Reid
Methylated arsenic (As) species represent a significant fraction of the As accumulating in rice grains, and there are geographic patterns in the abundance of methylated arsenic in rice that are not understood. The microorganisms driving As biomethylation i ...
