Abstract (sommario):
Introduction: It has been reported that the principal source of exposure for humans to inorganic arsenic (As) comes from drinking water. It is known that selenium (Se) competes with the reductive metabolism and methylation of As and Se compete for the availability of glutathione. The overarching goal of this dissertation research is to assess relationships between arsenic intake from water and other fluids with urinary arsenic output and then to assess how urinary arsenic output is modified by selenium exposure. Methods: Households in the Binational Arsenic Exposure Survey (BAsES) were selecte

Abstract (sommario):
The properties of an element are highly dependent on its chemical form, it’s called elemental speciation. This study evaluates the arsenic species found in a range of food stuffs together with growing environments and toxicity issues. Total arsenic concentrations in fish tissue and vegetable crops were determined by ICP-MS following microwave-assisted acid digestion using nitric acid/hydrogen peroxide, trypsin and cellulase enzymatic extraction procedures. The extracted arsenic species were then quantified using HPLC-ICP-MS. A dilute nitric acid (1 % (v/v)) digestion procedure was also used to

Abstract (sommario):
AbstractArsenic (As) contamination of groundwater and surface water is a worldwide problem. Exposure to arsenic in drinking water is an important current public health issue. Arsenic is well known for its carcinogenic and teratogenic effects. The U.S. Environmental Protection Agency (USEPA) has recently enacted a stricter drinking water standard for arsenic that lowers the maximum contaminant level (MCL) from 50 to 10 ug l-1.Localized elevated As concentrations in groundwater or surface water have been attributed to the natural release of As from the weathering of As bearing minerals.

Abstract (sommario):
Arsenic (As) is a toxic semi-metallic element found in groundwater, soils, and plants. Natural and anthropogenic sources contribute to the distribution of arsenic in the environment. Arsenic’s toxic and mobile behavior is associated with its speciation ability. There are two types of arsenic available to the environment, inorganic and organic arsenic. Of the two, inorganic arsenic is more toxic to humans and more mobile in the environment. Two inorganic compounds responsible for arsenic contamination are trivalent arsenite, As (III), and pentavalent arsenate, As (V). Trivalent arsenate is cons

Abstract (sommario):
Arsenic (As), a metalloid occurring ubiquitously in nature in organic and inorganic forms, is classified as a potent carcinogen. Among the inorganic forms which are more toxic, AsIII has a high affinity to bind with sulfhydryl groups of the amino acid cysteine, affecting many key metabolic processes such as fatty acid metabolism and glutathione production. AsV is a phosphate analogue and can substitute the inorganic phosphate affecting nucleotide synthesis and energy homeostasis of the cell. Much of the research on As in plants focuses on rice as it is the major source of dietary As intake and

Abstract (sommario):
Arsenic is a ubiquitous environmental toxic substance. As a consequence of continual exposure to arsenic, nearly every organism, from Escherichia coli to humans have evolved arsenic detoxification pathways. One of the pathways is extrusion of arsenic from inside the cells, thereby conferring resistance. The R773 arsRDABC operon in E. coli encodes an ArsAB efflux pump that confers resistance to arsenite. ArsA is the catalytic subunit of the pump, while ArsB forms the oxyanion conducting pathway. ArsD is an arsenite metallochaperone that binds arsenite and transfers it to ArsA. The interaction o
