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) …

Manganese (Mn) is an abundant element in terrestrial and coastal ecosystems and an
essential micronutrient in the metabolic processes of plants and animals. Mn is generally not …

Coastal wetlands host large and dynamic reservoirs of organic carbon (C) and are also
biogeochemical hotspots for a wide range of Fe (hydr-) oxides with different chemical …

To improve our understanding of the carbon cycling response to imminent sea-level rise and
saltwater intrusions, we review the existing literature on the likely effects of the increasing …

Jarosite can be an important scavenger for arsenic (As) and antimony (Sb) in acid mine
drainage (AMD) and acid sulfate soil (ASS) environments. When subjected to reducing …

Microbial sulfate reduction is an important terminal electron accepting process in arsenic-
contaminated subsurface environments. Humic acids are ubiquitous in such environments …

This study explores interactions between As and Fe (III) minerals, predominantly
schwertmannite and jarosite, in acid mine drainage (AMD) via observations at a former mine …

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

Microbial sulfidogenesis plays a potentially important role in Fe and As biogeochemistry
within wetland soils, sediments and aquifers. This study investigates the specific effects of …
