The cycling processes of elemental manganese (Mn), including the redox reactions of
dissolved Mn (III)(dMn (III)), directly and indirectly influences the biogeochemical processes …

Lignin has been analysed as a proxy for vegetation change in the Quaternary science
literature since the early 1990s in archives such as peat, lakes, and intertidal and marine …

Aqueous and methanolic extracts of several microalgae (Ankistrodesmus sp., Spirogyra sp.,
Euglena cantabrica, and Caespitella pascheri) and cyanobacteria (Nostoc sp., Nostoc …

On-going permafrost thaw in discontinuous permafrost regions produces significant amounts
of small permafrost subsidence and depressions, while large lakes are likely to drain into …

Among the most abundant biopolymers in the biosphere, lignin represents an untapped
opportunity to create novel bioproducts. In this article, we discuss possibilities to synthesize …

Dissolved iron (dFe) and organic dFe-binding ligands were determined in San Francisco
Bay, California by competitive ligand exchange adsorptive cathodic stripping voltammetry …

The speciation of iron (III) in oxic seawater is dominated by its hydrolysis and sedimentation
of insoluble iron (III)-oxyhydroxide. As a consequence, many oceanic areas have very low …

Organic soils in the Arctic–boreal region produce small aquatic humic ligands (SAHLs), a
category of naturally occurring complexing agents for iron. Every year, large amounts of …

The small mountainous rivers of Oceania discharge a large fraction of their dissolved and
particulate load of materials within a very small percentage of the time. As a result, the yearly …

Abstract Tetravalent actinides, An (IV), are usually assumed to be little mobile in near-neutral
environmental waters because of their low solubility. However, there are certain …
