Millions of tons of riverine plastic waste enter the ocean via estuaries annually. The plastics
accumulate, fragment, mix and interact with organisms in these dynamic systems, but such …

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 formation of Fe (III) oxyhydroxide colloids by oxidation of Fe (II) and their subsequent
aggregation to larger particles were studied in laboratory experiments with natural water …

Cross-flow ultrafiltration studies were carried out in the Trinity river estuary of Galveston Bay
in July, 1993, May, 1994 and July 1995 to study the phase speciation for a number of metals …

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 distribution of several trace metals has been studied in the surface waters of Galveston
Bay, Texas, in order to assess the impact of complexation with organic and reduced sulfur …

Changes in size distribution and elemental composition of 0.5–50nm fresh water colloids
during estuarine mixing have been studied by in-laboratory mixing of natural creek water …

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 …

A series of laboratory and field studies were conducted to test suitability and optimal
sampling conditions of an Amicon ultrafiltration system for the collection of colloidal material …
