The degree of pyritization and degree of trace metal pyritization (DTMP) were investigated in
sediments from Ghar El Melh Lagoon (northern Tunisia) in order to study metal deposition. A …

The role of microbial vs. abiotic processes in ooid formation has been a controversial topic
for over a century. Recent sedimentological, geochemical and biomarker data indicate that …

The gill is the organ by which many toxic metals are taken up by crustaceans. Iron is known
to precipitate at its surface, a phenomenon recently observed in some tropical aquaculture …

Abstract Sulfate (SO 4 2−) has received attention as means of monitoring water quality and
pollution. However, the SO 4 2− content of rivers, lakes, and reservoirs varies significantly by …

Many marshes show signs of degradation due to fragmentation, lack of sediment inputs, and
erosion which may be exacerbated by sea level rise and increasing storm …

The biogeochemical cycles of iron, phosphorus and sulfur are intimately linked and the fate
of these elements is highly redox-dependent. Under anoxic conditions, iron is reduced to Fe …

Alluvial aquifers contaminated by geogenic arsenic often lack direct solid-phase speciation
data, hindering efforts to understand landscape-scale spatial heterogeneity and controls on …

Coastal areas can contain a highly valuable archaeological record because of post‐glacial
drowning of previously inhabited land surfaces. Such records are increasingly under threat …

Soils in boundary conditions of contrasting ecosystems generally show unique features.
Transition often leads to changes in soil-forming processes, whereby the environment never …

Iron (Fe) speciation and microbial reducible Fe (III) oxides (MR-Fe (III)) in surface sediments
of semi-enclosed Jiaozhou Bay were quantified to reveal Fe geochemistry in the settings …
