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 ...
Mechanisms of removal of heavy metals and arsenic from water by TiO2-heterogeneous photocatalysis
(De Gruyter, 2015-06)
This article is an overview of recent work performed in our laboratory on TiO2 heterogeneous photocatalysis of aqueous systems containing toxic forms of chromium, arsenic, lead, uranium and mercury. The cases of chromium ...
Urinary arsenic speciation profile in ethnic group of the Atacama desert (Chile) exposed to variable arsenic levels in drinking water
(2015)
Ethnic groups from the Atacama Desert (known as Atacameños) have been exposed to natural arsenic pollution for over 5000 years. This work presents an integral study that characterizes arsenic species in water used for human ...
A simple voltammetric procedure for speciation and evaluation of As removal from water

Electrochemical generation of arsenic volatile species using a gold mercury amalgaman cathode. Determination of arsenic by atomic absorption spectrometry.
(Netherlands, 2015)
The electrochemical generation of arsenic volatile species (arsine) using an Au/Hg amalgam cathode in a 0.5 M H2SO4 solution, is described. Results were compared with those obtained with other cathodes commonly used for ...
Nitric oxide attenuates oxidative stress induced by arsenic in lettuce (Lactuca sativa) leaves
(Water, Air, & Soil Pollution, 2019)
ArsH protects Pseudomonas putida from oxidative damage caused by exposure to arsenic
(2020-03-23)
The two As resistance arsRBC operons of Pseudomonas putida KT2440 are followed by a downstream gene called arsH that encodes an NADPH‐dependent flavin mononucleotide reductase. In this work, we show that the arsH1 and (to ...
Arsenic speciation analysis in mono-varietal wines by on-line ionic liquid-based dispersive liquid-liquid microextraction
(Elsevier, 2012-11-08)
A highly efficient separation and pre-concentration method for arsenic species determination, based on ionic liquid (IL) dispersive microextraction technique implemented in a flow analysis system, is proposed. Arsenite ...
