Abstract:
It has recently been discovered that organic and inorganic arsenics could be detrimental to human health. Although organic arsenic is less toxic than inorganic arsenic, it could form inorganic arsenic through chemical and biological processes in environmental systems. In this regard, the availability of tools for detecting organic arsenic species would be beneficial. Because As-sensing biosensors employing arsenic responsive genetic systems are regulated by ArsR which detects arsenics, the target selectivity of biosensors could be obtained by modulating the selectivity of ArsR. In this study,

Abstract:
Environmental Context. Arsenic occurs in rock, fresh water and seawater. Organic arsenic compounds are found as natural constituents of many organisms and, because some, e.g. seafood, are consumed by humans, there is ongoing health interest in their arsenic content. Thio-arsenicals, a newly discovered group of arsenic compounds, may be integral to understanding the environmental behaviour of arsenic. This paper reviews recent research in arsenic environmental chemistry and discusses ideas intended to stimulate future research in this area. Abstract. Recent results in the field of arsenic envir

Abstract:
The dramatic increase in hydrometallurgical extraction of gold from arsenic bearing gold ores has inevitably resulted in the release of arsenic into the environment worldwide. Residual arsenic minerals in tailings storage facilities can be oxidised and mobilise arsenic into the environment. This can contaminate soils, ground and surface waters and eventually biota. In spite of well-established technologies and recent advances in arsenic remediation, there are limited knowledge and understanding of the iron oxide substrate (goethite, hematite and magnetite) mineralogy and the fate of arsenic on

The electrochemical behavior of the four arsenic species, As(III), As(V), monomethylarsonic acid (MMA), and dimethylarsinic acid (DMA), was examined at a gold disk electrode. The As(III) species in solution was determined by anodic stripping voltammetry. The experimental conditions that were established for this determination were employed for the determination of As(III) that was formed by the reduction of As(V) by glutathione. The presence of an Arsenic(III)-glutathione complex in solution was established by cyclic voltammetry.

Arsenic contamination in drinking water is a severe problem worldwide. The best way to prevent hazardous diseases from chronic arsenic exposure is to remove the exposure. Efforts to remediate arsenic in drinking water have taken two tracks. One is to provide surface or shallow well water sources as an alternative to the arsenic contaminated deep wells. Another approach is to remove arsenic from the contaminated water. Different removal technologies like oxidation, chemical coagulation, precipitation, adsorption and others are available.

Arsenic speciation in soils and sediments pose a great challenge due to possible conversion and/or re-adsorption. Since arsenic toxicity is dependent on its chemical species, the purpose of this research is to study the extraction process, determine what factors control species change, and develop an extraction method which preserves the arsenic species during extraction for proper quantitation. After investigating the addition of reagents such as hydroxylamine and ethylenediamine-tetraacetic acid (EDTA) without significant improvement, a method was established for the extraction of mobile or
