Arsenic is a metalloid whose name conjures up images of murder. Nonetheless, certain
prokaryotes use arsenic oxyanions for energy generation, either by oxidizing arsenite or by …

During the past decade, interest in chemical reactions occurring at metal oxide-aqueous
solution interfaces has increased significantly because of their importance in a variety of …

Arsenic derived from natural sources occurs in groundwater in many countries, affecting the
health of millions of people. The combined effects of As (V) reduction and diagenesis of iron …

Although some heavy metals are essential trace elements, most of them can be toxic to all
forms of life at high concentrations due to formation of complex compounds within the cell …

Organic matter is important for controlling arsenic reduction and release under anoxic
conditions. Humic substances (HS) represent an important fraction of natural organic matter …

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 …

In the deltaic plain of the Ganges‐Meghna‐Brahmaputra Rivers, arsenic concentrations in
groundwater commonly exceed regulatory limits (> 50 µg L− 1) because FeOOH is …

Arsenic mobility in natural environments is controlled primarily by sorption onto metal oxide
surfaces, and the extent of this sorption may be influenced strongly by the presence of other …

Arsenic occurs naturally in the earth's crust and is widely distributed in the environment.
Natural mineralization and activities of microorganisms enhance arsenic mobilization in the …

Arsenic (As) distribution and toxicology in the environment is a serious issue, with millions of
individuals worldwide being affected by As toxicosis. Sources of As contamination are both …
