WHAM—a chemical equilibrium model and computer code for waters, sediments, and soils incorporating a discrete site/electrostatic model of ion-binding by humic substances
TL;DR: The WHAM (Windermere Humic Aqueous Model) as mentioned in this paper is a simple inorganic speciation code for aqueous solutions that combines Humic Ion-Binding Model V with a simple, inorganic inorganic specciation code.

Ion binding to natural organic matter : competition, heterogeneity, stoichiometry and thermodynamic consistency
David G. Kinniburgh,Willem H. van Riemsdijk,Luuk K. Koopal,Michal Borkovec,Marc F. Benedetti,Marcelo Javier Avena +5 more
TL;DR: The NICCA-Donnan model as mentioned in this paper is a semi-empirical model that is similar to the NICA-donnan model except that it introduces an additional degree of scaling that ensures thermodynamic consistency and allows for variable stoichiometry of binding, which implicitly accounts for the large degree of chemical heterogeneity of humic particles.
Journal ArticleDOI
A unifying model of cation binding by humic substances
TL;DR: Model V describes the binding of ions by humic substances in terms of complexation at discrete sites, modified by electrostatic attraction and/or repulsion, and also takes account of nonspecific binding due to counterion accumulation.
Journal ArticleDOI
A Generalized Description of Aquatic Colloidal Interactions: The Three-colloidal Component Approach
TL;DR: In this article, the physicochemical properties of the different groups of colloids are described, and the role of each colloid class is discussed with respect to homoaggregation (aggregation within a given colloid) and hetero-aggregation among different colloid types.
Journal ArticleDOI
The effect of humic acid adsorption on pH-dependent surface charging and aggregation of magnetite nanoparticles
Erzsébet Illés,Etelka Tombácz +1 more
TL;DR: The pH-dependent adsorption of humic acid (HA) on magnetite and its effect on the surface charging and the aggregation of oxide particles were investigated and nanoparticles are stabilized in a way of combined steric and electrostatic effects.

Trace metals: inputs, sedimentation and accumulation in San Vicente Bay, Chile.
Ramón Ahumada,José Vargas +1 more
TL;DR: Experimental data on sedimentation and sediment abundance were consistent with field observations on distribution and accumulation at sites of major sedimentation in this bay and rates of bottom sediment accumulation are estimated in relation to the time of residence of water in the bay.
Journal ArticleDOI
Mercury and arsenic in the surface peat soils of the Changbai Mountains, northeastern China: distribution, environmental controls, sources, and ecological risk assessment
Jia Liu,Zucheng Wang,Hong-Yan Zhao,Matthew Peros,Qian-Nan Yang,Shasha Liu,Hong-Kai Li,Shengzhong Wang,Zhao-Jun Bu +8 more
TL;DR: Overall, Hg and As in the peatlands of the Changbai Mountains pose a moderate level of potential risk to ecological health.

Chapter 6 U- and Th-Series Nuclides in Estuarine Environments
TL;DR: In this paper, the authors examined U- and Th-series series nuclides that enter estuaries, their fate within the estuary and their input to the ocean, and their half-life and reaction rates differ widely relative to the residence time of water within an estuary.
Journal ArticleDOI
Study of the interaction of a cis-dichloroaminopyrrolidine Pt(II) complex and the polynucleotide poly(I)–poly(C) acid by means of -NMR and multivariate curve resolution
TL;DR: In this paper, a multivariate curve resolution (MCR-ALS) was applied for the first time to analyze 1 H-NMR data, which allowed to determine the number of interaction complexes and the recovery of both kinetic concentration profiles and pure NMR spectra for all the detected species.

Comparative Evaluation of Scanned Stripping Techniques: SSCP vs. SSV
Raewyn M. Town,H.P. van Leeuwen +1 more
TL;DR: In this paper, the authors evaluated the performance of stripping voltammetry and chronopotentiometry (SSCP) for identifying metal ion speciation features and susceptibility to typical interferences for conventional (HMDE) and microelectrodes.
