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.

The role of geochemistry in environmental and epidemiological studies in developing countries: a review
TL;DR: The role of geochemistry in the preparation of high resolution baseline data to identify potential hazards, understanding the pathways of chemical elements from rocks and soils to man and animals, and developing amelioration strategies to reduce the impacts of inappropriate land use, power generation and mining is discussed in this paper.
Journal ArticleDOI
A nickel availability study in serpentinised areas of Portugal
TL;DR: In this paper, the factors that control Ni availability and adsorption in serpentine soils from the northeast of Portugal, which developed under temperate climacteric conditions, were investigated following characterisation of the soils' selected physicochemical properties.
Journal ArticleDOI
Complexation of Cd(II) and Pb(II) with humic acids studied by anodic stripping voltammetry using differential equilibrium functions and discrete site models
Gilberto Abate,Jorge C. Masini +1 more
TL;DR: In this paper, the binding of CdII and Pb(II) to two humic acids was studied by differential pulse anodic stripping voltammetry using continuous differential equilibrium functions and linear Scatchard plots.
Journal ArticleDOI
Labile/inert metal species in aquatic humic substances: an ion-exchange study
TL;DR: An ion exchange procedure has been developed for the analytical fractionation of metals (e.g., Al, Co, Cu, Fe, Mn, Ni, Pb, Zn) forming labile/inert complexes with aquatic humic substances (HS) isolated from bog, forest, ground and lake water as discussed by the authors.

The effect of pH and atmospheric deposition on concentrations of trace elements in acidified freshwaters: A statistical approach
Josef Veselý,Vladimír Majer +1 more
TL;DR: In this article, a statistical evaluation of freshwaters from little polluted stream basins in the Czech Republic indicated a relationship between the Pb, Cu, Zn, Cd, Be, As, Mn, Sr, F− and Fe concentrations and the pH, over a range of pH 3.6 to 9.6.
