This paper reviews the current knowledge on the toxicity, speciation and biogeochemistry of
arsenic in aquatic environmental systems. The toxicity of arsenic is highly dependent on the …

Aqueous arsenic speciation, or the chemical forms in which arsenic exists in water, is a
challenging, interesting, and complicated aspect of environmental arsenic geochemistry …

Concentrations of naturally occurring arsenic in ground water vary regionally due to a
combination of climate and geology. Although slightly less than half of 30,000 arsenic …

Arsenic is a toxic metalloid whose mobility and availability are largely controlled by sorption
on sulfide minerals in anoxic environments. Accordingly, we investigated reactions of As (III) …

The mechanisms whereby As (III) and As (V) in aqueous solution (pH 5.5− 6.5) interact with
the surfaces of goethite, lepidocrocite, mackinawite, and pyrite have been investigated using …

This book presents an overview of the chemistry, geology, toxicology and environmental
impacts of arsenic, presenting information on relatively common arsenic minerals and their …

X-ray absorption fine structure spectroscopy (XAFS) was used to determine arsenic (As)
oxidation state, local coordination (to a radius of nearly equal Aa around As), and the …

Arsenic Contamination in the World: an International Sourcebook provides a global
compendium of cited arsenic occurrences in the world as they affect public health. This book …

Wetlands cover more than 6% of the global ice-free land area, and have been recognized as
important sinks for arsenic. Wetland soils and sediments are subject to frequent changes in …

Groundwater contamination by arsenic in Vietnam poses a serious health threat to millions
of people. In the larger Hanoi area, elevated arsenic levels are present in both, the …
