Correlation between Iron Reducibility in Natural and Iron-Modified Clays and Its Adsorptive Capability for Arsenic Removal
(Shanghai University, 2016-05)
The study reports aspects that allowed to correlate structural and redox properties of iron species deposited on clay minerals with the capacity of geomaterials for arsenic removal. Natural ferruginous clays as well as an ...
Concentration of arsenic in water, sediments and fish species from naturally contaminated rivers
(Springer, 2012-11)
Arsenic (As) may occur in surface freshwater ecosystems as a consequence of both natural contamination and anthropogenic activities. In this paper, As concentrations in muscle samples of 10 fish species, sediments and ...
Arsenic-tolerant microbial consortia from sediments of Copahue geothermal system with potential applications in bioremediation
(Wiley VCH Verlag, 2019-05)
Although arsenic (As) is recognized as a toxic element for living species, some microorganisms have the ability to tolerate and transform it; recent studies have proposed to take advantage of such capacity to develop ...
On-line speciation and quantification of four arsenical species in rice samples collected in Argentina using a HPLC–HG–AFS coupling
(2015)
An investigation was carried out to explore further the analytical capabilities of the coupling high performance
liquid chromatography (HPLC)–hydride generation (HG)–atomic fluorescence spectrometry (AFS) for the
reliable ...
Introducing simple detection of bioavailable arsenic at Rafaela (Santa Fe Province, Argentina) using the ARSOlux biosensor
(Molecular Diversity Preservation International, 2015-05)
Numerous articles have reported the occurrence of arsenic in drinking water in Argentina, and the resulting health effects in severely affected regions of the country. Arsenic in drinking water in Argentina is largely ...
Genome comparison of two Exiguobacterium strains from high altitude andean lakes with different arsenic resistance: identification and 3D modeling of the Acr3 efflux pump
(Frontiers Media, 2015-07)
Arsenic exists in natural systems in a variety of chemical forms, including inorganic arsenite (As [III]) and arsenate (As [V]). The majority of living organisms have evolved various mechanisms to avoid occurrence of arsenic ...
Theoretical study on the electronic and catalytic properties of Fe-doped TiO2 and its use in the removal of arsenic
(Universidad Nacional del Litoral, 2019)
Arsenic (As) is atoxic element that can be fatal to humans. In the environment, it exists indifferent oxidation states (-III, 0, + III and + V). However, in natural water,the As is mainly found in inorganic form forming ...
Distribution of inorganic arsenic species in groundwater from Central-West Part of Santa Fe Province, Argentina
(Pergamon-Elsevier Science Ltd, 2013-12)
The distribution of inorganic arsenic species in groundwater used as drinking water supply by the peri-urban and rural population from central-western area of Santa Fe Province, Argentina, was studied. An analytical ...
Screening of Toxic Inorganic Arsenic Species in Garlic (Allium sativum L.)
(2011)
It has been evidenced that arsenic in garlic is present in the most toxic inorganic species As(III) and As(V). A non-chromatographic speciation method has been developed for the screening of inorganic toxic species of As ...
Arsenic absorption and excretion in chronically exposed developing toad Rhinella arenarum
(Elsevier Science, 2017-06)
We assessed the toxicodynamics of As in developing Rhinella arenarum toad embryos and larvae exposed from fertilization to 0.01–10 mg As L−1. We determined As content in toad embryos and larvae by X-ray fluorescence ...
