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) …

The effect of acid-volatile sulfide (AVS) oxidation on Fe− S cycling and water quality in
coastal flood plain drains from acid-sulfate soil landscapes was examined using natural …

Most of the cadmium (Cd) accumulated in rice grains is derived from its remobilization in
soils during the grain filling period when paddy water is drained. The factors affecting Cd …

Sulfur biogeochemical cycling and associated Fe–S mineralization processes exert a major
influence over acidity dynamics, electron flow and contaminant mobility in wetlands, benthic …

Freshwater re-flooding is a relatively novel approach to remediate drained acid sulfate soil
(ASS) wetlands. This study documents the geochemical consequences of restoring …

Life and element cycling on Earth is directly related to electron transfer (or redox) reactions.
An understanding of biogeochemical redox processes is crucial for predicting and protecting …

Iron (oxyhydr) oxides and organic matter (OM) are intimately associated in natural
environments, and their fate might be linked to sulfur during sulfidation–reoxidation cycling …

The wetland constructed at the Big Five Tunnel in Idaho Springs, Colorado was designed to
remove, passively, heavy metals from acid mine drainage. In optimizing the design of such a …

Acid sulfate soils (ASS) are wide-spread in coastal and inland wetlands. When sulfidic ASS
are exposed to oxygen, sulfuric acid is generated which can threaten wetlands and …

Tailings generated during processing of sulfide ores represent a substantial risk to water
resources. The oxidation of sulfide minerals within tailings deposits can generate low-quality …
