Environmental Context. The fate and behaviour of trace pollutants are very strongly
modified, and usually dominated, by their physical and chemical interactions with naturally …

Trace metals play an important role in the regulation of primary productivity and
phytoplankton community composition. Metal species directly affects the biogeochemical …

The chemical properties of organic matter affect important soil processes such as speciation,
solubilization, and transport of plant nutrients and metals. This work uses ultrahigh …

Topsoils are often contaminated by trace metals, and it is important to understand how
different processes govern the transport of such metals to fresh and marine waters. This …

Colloids, conventionally defined as macromolecules and nanoparticles with sizes ranging
between 1 and 1000 nm, are known to be abundant in aquatic systems. In fact, the mass …

This chapter covers the fundamental coordination chemistry, environmental chemistry, and
biochemistry of Pb (II), with particular emphasis on spectroscopic properties, structures, and …

Minerals with large specific surface areas promote the stabilization of soil organic matter
(SOM). We analysed three acidic soils (dystric, skeletic Leptic Cambisol; dystric, laxic Leptic …

Water samples were collected from six small rivers in the Yukon River basin in central
Alaska to examine the role of colloids and organic matter in the transport of trace elements in …

Dialysis experiments with arsenate and three different NOM samples amended with Fe (III)
showed evidence confirming the formation of aquatic arsenate− Fe (III)− NOM associations …

Few studies have so far examined the kinetics and extent of the formation of Fe-colloids in
the presence of natural organic ligands. The present study used an experimental approach …
