Heavy metals are widespread toxic environmental pollutants that can generate enormous
health and public concern. Iron (oxyhydr) oxides are ubiquitous in both natural and …

The exposure to low or high concentrations of arsenic (As), either due to the direct
consumption of As contaminated drinking water, or indirectly through daily intake of As …

The mechanisms involved in the activation of persulfate by nanosized zero-valent iron
(NZVI) were elucidated and the NZVI transformation products identified. Two distinct reaction …

The attention of mining industry has directed towards the processing of complex arsenic-
bearing minerals due to a decrease in the traditional base metal reserves. Arsenic present in …

Arsenic (As) contamination is a well-recognized environmental and health issue, threatening
over 200 million people worldwide with the prime cases in South and Southeast Asian and …

In this article, we provide a critical review on the occurrence, formation, structure and stability
of schwertmannite–an enigmatic Fe (III) oxyhydroxy-sulfate mineral that is of widespread …

Acid sulfate soils (ASS) contain substantial quantities of iron sulfide minerals or the oxidation
reaction products of these sulfidic minerals. Transformation of iron (Fe) and sulfur (S) …

Arsenic is a commonly occurring toxic metal in natural systems and is the root cause of many
diseases and disorders. Occurrence of arsenic contaminated water is reported from several …

Abstract The Macleay River in eastern Australia is severely impacted by historic stibnite-and
arsenopyrite-rich mine-tailings. We explore the partitioning, speciation, redox-cycling …

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