Arsenic speciation and mobility in mine wastes from a copper–arsenic mine in Devon, UK : an SEM, XAS, sequential chemical extraction study [PDF]

, 2007
The nature of As speciation is a determining factor for As mobility in mine wastes. In this study, scanning electron microscopy (SEM), X-ray absorption spectroscopy and sequential chemical extraction methods were used for the environmental ...

Metabolism of low-dose inorganic arsenic in a central European population: influence of sex and genetic polymorphisms. [PDF]

, 2007
BACKGROUND: There is a wide variation in susceptibility to health effects of arsenic, which, in part, may be due to differences in arsenic metabolism.

Variations of arsenic forms and the role of arsenate reductase in three hydrophytes exposed to different arsenic species

Ecotoxicology and Environmental Safety, 2021
In order to understand the mechanisms of arsenic (As) accumulation and detoxification in aquatic plants exposed to different As species, a hydroponic experiment was conducted and the three aquatic plants (Hydrilla verticillata, Pistia stratiotes and ...

Microbial contributions to coupled arsenic and sulfur cycling in the acid-sulfide hot spring Champagne Pool, New Zealand

Frontiers in Microbiology, 2014
Acid-sulfide hot springs are analogs of early Earth geothermal systems where microbial metal(loid) resistance likely first evolved. Arsenic is a metalloid enriched in the acid-sulfide hot spring Champagne Pool (Waiotapu, New Zealand).

Arsenic Speciation in Manufactured Seafood Products

Journal of Food Protection, 1998
The literature on the speciation of arsenic (As) in seafoods was critically reviewed. Most research has been directed toward fresh seafood products with few papers dealing with As speciation in manufactured seafoods. Predictions concerning As species made on the basis of fresh seafood products cannot be extrapolated to manufactured seafoods. Therefore,

Arsenate impact on the metabolite profile, production and arsenic loading of xylem sap in cucumbers (Cucumis sativus L.)

Frontiers in Physiology, 2012
Arsenic uptake and translocation studies on xylem sap focus generally on the concentration and speciation of arsenic in the xylem. Arsenic impact on the xylem sap metabolite profile and its production during short term exposure has not been reported in ...

Arsenic Speciation Analysis in Human Saliva [PDF]

Clinical Chemistry, 2008
Abstract Background: Determination of arsenic species in saliva is potentially useful for biomonitoring of human exposure and studying arsenic metabolism. Arsenic speciation in saliva has not been reported previously. Methods: We separated arsenic species in saliva using liquid chromatography (LC) and quantified them by ...
