Origin, distribution, and geochemistry of arsenic in the Altiplano-Puna plateau of Argentina, Bolivia, Chile, and Perú
(Elsevier Science, 2019-05)
Elevated concentrations of arsenic in water supplies represent a worldwide health concern. In at least 14 countries of South America, high levels have been detected relative to international standards and guidelines. Within ...
Ethnic characterization of a population of children exposed to high doses of arsenic via drinking water and a possible correlation with metabolic processes
(e-Century Publishing, 2014-01)
Because the ratio between the two major arsenic metabolites is related to the adverse health effects of arsenic, numerous studies have been performed to establish a relationship between the ability to metabolically detoxify ...
Metagenomic study of red biofilms from Diamante Lake reveals ancient arsenic bioenergetics in haloarchaea
(Nature Publishing Group, 2015-07)
Arsenic metabolism is proposed to be an ancient mechanism in microbial life. Different bacteria and archaea use detoxification processes to grow under high arsenic concentration. Some of them are also able to use arsenic ...
Water Dilutes and Alcohol Concentrates Urinary Arsenic Species When Food is the Dominant Source of Exposure
(2019-01-01)
Exposure to certain arsenic (As) species has been associated with increased cancer risk and a wide range of other health concerns, even at low levels. Here we used urine as a biomarker of As internal dose in a well-characterized ...
Arsenic hyperaccumulation induces metabolic reprogramming in Pityrogramma calomelanos to reduce oxidative stress
(Physiologia Plantarum, 2018)
Effects of plant age on arsenic hyperaccumulation by Pteris vittata L.
(2007)
Plant age affects its elemental uptake and biomass accumulation, which is important for the application of plants in phytoextraction. In this research, we evaluated the effects of plant age on arsenic accumulation by arsenic ...
Mercury (Hg), lead (Pb), cadmium (Cd), selenium (Se), and arsenic (As) in liver, kidney, and feathers of gulls: A Review
(Springer New York LLC, 2019)
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 ...
