Proper understanding of the basic processes and specific properties of engineered
nanomaterials (NMs) that modify the fate and effects of NMs is crucial for NM-tailored risk …

Estuaries are dynamic mixing zones where river water interacts with seawater, resulting in
large and complex geochemical changes. How two key factors, particle aggregation and pH …

The stability and aggregation behavior of iron oxide colloids in natural waters play an
important role in controlling the fate, transport, and bioavailability of trace metals. Time …

Environmental context. It is now well accepted that iron is an essential micronutrient for
phytoplankton growth in many areas of the global ocean, even though this element is …

The origin and nature of interparticle forces acting on colloid surfaces in natural waters has
been examined using an atomic force microscope. Natural colloids were represented by a …

Peat bogs have the ability to produce strong chelate ligands (humic and fulvic acids) which
enhance the weathering rates of iron-silicate minerals and greatly increase the solubility of …

Abstract The Pearl River Estuary (PRE), the largest estuary in Southern China, regulates the
fluxes of riverine trace metals into the South China Sea. However, the geochemical behavior …

Recent studies have suggested that rivers may present an isotopically light Fe source to the
oceans. Since the input of dissolved iron from river water is generally controlled by …

Glacial meltwater systems supply the Arctic coastal ocean with large volumes of sediment
and potentially bioavailable forms of iron, nitrogen and carbon. The particulate fraction of …

Primary production in large areas of the open ocean is limited by low iron concentrations.
Rivers are potential sources of iron to the ocean, however, riverine iron is prone to intense …
