Acid mine drainage (AMD) is often accompanied with elevated concentrations of arsenic, in
the forms of arsenite, As (III), and/or arsenate, As (V), due to the high affinity of arsenic for …

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

Awareness of the problems associated with arsenic in drinking water and the environment
has grown significantly over the last two decades or so and today an enormous literature …

Recognition of arsenic (As) contamination of shallow fluvio-deltaic aquifers in the Bengal
Basin has resulted in increasing exploitation of groundwater from deeper aquifers that …

Sorption and oxidation reactions in the environment may affect substantially the mobility of
redox-sensitive toxic trace elements and compounds. Investigating the environmental factors …

Redox transformation of arsenic strongly influences its fate and transport in the environment.
It is of interest to investigate heterogeneous oxidation of As (III) on the surface of major metal …

In the Bengal Basin, the land surface exposed during the last lowstand of sea level around
20 ka, and now buried by Holocene sediment, is capped by an effectively impermeable clay …

A thermodynamic dataset for arsenic species in As–O–H–S–Fe–Ba system was compiled
from the literature. Using this dataset, Eh–pH diagrams for the systems As–O–H, As–O–H–S …

Arsenic (As) contamination in soil and water poses a serious threat to the ecosystem health
and human beings, and is of widespread concern. The main As species found in soil and …

In this study, the sorption properties of iron-and iron–manganese-modified clinoptilolite-rich
tuffs used to remove As (III) and As (V) from aqueous solutions were investigated. Factors …
