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 …

Arsenic and selenium are readily metabolized by prokaryotes, participating in a full range of
metabolic functions including assimilation, methylation, detoxification, and anaerobic …

Uncovers the Key Role Microbes Play in the Transformation of Oxidizable and Reducible
MineralsMany areas of geomicrobial processes are receiving serious attention from …

The typical scales for plant and fungal movements vary over many orders of magnitude in
time and length, but they are ultimately based on hydraulics and mechanics. We show that …

Sorption to iron (Fe) minerals determines the fate of the toxic metalloid arsenic (As) in many
subsurface environments. Recently, thiolated As species have been shown to dominate …

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

Mono-, di-, tri-, and tetrathioarsenate, as well as methylated arsenic oxy-and thioanions,
were determined besides arsenite and arsenate in geothermal waters of Yellowstone …

Arsenic (As) contamination in geothermal systems has been identified in many areas of the
world. Arsenic mobilization from rocks and mineral phases into geothermal fluids depends …

The seasonal variation in lake water arsenic (As) and antimony (Sb) concentrations was
assessed in four small (< 1.5 km 2) subarctic lakes impacted by As and Sb emissions from …

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 …
