Failure to accurately predict acid rock drainage (ARD) leads to long-term impacts on
ecosystems and human health, in addition to substantial financial consequences and …

Chromium (Cr) is a heavy metal of commercial importance; thus, significant amounts are
released in wastewaters. The mobility and distribution of metals in the environment is related …

Methane is a powerful greenhouse gas and its biological conversion in marine sediments,
largely controlled by anaerobic oxidation of methane (AOM), is a crucial part of the global …

Studies of authigenic phosphorus (P) minerals in marine sediments typically focus on
authigenic carbonate fluorapatite, which is considered to be the major sink for P in marine …

The sulfur biogeochemical cycle plays a key role in regulating Earth's surface redox through
diverse abiotic and biological reactions that have distinctive stable isotopic fractionations. As …

Seasonal oxygen depletion (hypoxia) in coastal bottom waters can lead to the release and
persistence of free sulfide (euxinia), which is highly detrimental to marine life. Although …

Phosphorus is an essential nutrient for life. The release of phosphorus from sediments is
critical in sustaining phytoplankton growth in many aquatic systems and is pivotal to …

A new sequential extraction scheme for acid sulfate soil materials has been evaluated for
iron partitioning in a range of synthetic iron-bearing minerals and natural acid sulfate soil …

Cd is normally associated with sulfide and Fe oxides in flooded paddy soil. The mechanisms
of biochar enhanced Cd immobilization by promoting Fe transformation and sulfide …

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