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 ...
2021Methylation 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 ...
EPFL2020Coupled As and Mn Redox Transformations in an Fe(0) Electrocoagulation System: Competition for Reactive Oxidants and Sorption Sites
Sachiko Hirosue, Jasquelin Peña, Nathalie Manetti
Iron electrocoagulation (EC) can be used for the decentralized treatment of arsenic(As)-contaminated groundwater. Iron EC involves the electrolytic dissolution of an Fe(0) electrode to Fe(II). This process produces reactive oxidants, which oxidize As(III) ...
AMER CHEMICAL SOC2020Chromate tolerance and removal of bacterial strains isolated from uncontaminated and chromium-polluted environments
Rizlan Bernier-Latmani, Imrich Barak, Zuzana Chromiková
Investigation of bacterial chromate tolerance has mostly focused on strains originating from polluted sites. In the present study, we isolated 33 chromate tolerant strains from diverse environments harbouring varying concentrations of chromium (Cr). All of ...
2019A von Hamos spectrometer for in situ sulfur speciation by non-resonant sulfur K alpha emission spectroscopy
A von Hamos geometry based wavelength dispersive spectrometer combined with an in situ reactor cell has been developed to measure non-resonant sulfur K alpha emission for the in situ speciation of low concentrations of sulfur. The spectrometer operates at ...
2019Arsenic 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 ...
Amer Chemical Soc2017A Microfluidic Biodisplay
Sebastian Maerkl, Francesca Volpetti, Ekaterina Emilova Petrova
Synthetically engineered cells are powerful and potentially useful biosensors, but it remains problematic to deploy such systems due to practical difficulties and biosafety concerns. To overcome these hurdles, we developed a microfluidic device that serves ...
American Chemical Society2017Mechanistic Modeling of Genetic Circuits for ArsR Arsenic Regulation
Vassily Hatzimanikatis, Yves Berset
Bioreporters are living cells that generate an easily measurable signal in the presence of a chemical compound. They acquire their functionality from synthetic gene circuits, the configuration of which defines the response signal and signal-to-noise ratio. ...
Amer Chemical Soc2017Development and application of the adverse outcome pathway framework for understanding and predicting chronic toxicity: II. A focus on growth impairment in fish
Adverse outcome pathways (AOPs) organize knowledge on the progression of toxicity through levels of biological organization. By determining the linkages between toxicity events at different levels, AOPs lay the foundation for mechanism-based alternative te ...
