Lability and mobility effects on mixtures of ligands under steady-state conditions
TL;DR: In this paper, the steady-state flux arriving at an active surface from a mixture (in which one active species reacts with non-active ligands in the medium) can be characterized in terms of a list of dimensionless parameters involving the kinetic and mobility properties of each species.
Journal ArticleDOI
Trace metal speciation measurements in waters by the liquid binding phase DGT device.
TL;DR: Lower percentages of DGT labile copper concentrations over total filterable copper concentrations obtained from the deployments in freshwater sites indicated that copper complexes with organic matter were basically not measured by the devices.
Journal ArticleDOI
Experimental induction of morphological deformities in Chironomus riparius larvae by chronic exposure to copper and lead
TL;DR: The experiments demonstrated the potential of both an essential and a non-essential metal to induce weak deformities in a small proportion of a C. riparius population as well as the induction of deformities which are independent of metal stress or fluctuating over the generations, but warns for a careful interpretation of deformity scores.
Journal ArticleDOI
The molecular size of natural organic matter (NOM) determined by diffusivimetry and seven other methods.
TL;DR: The diffusion coefficients determined in this work (stirred diffusion cell) are about 70% higher than that determined by DAM, and agree well with diffusion coefficient determined by FCS, and molecular weights determined by HPSEC are of the same magnitude as molecular weights derived from diffusion coefficients.
Journal ArticleDOI
Environmental geochemistry at the global scale
TL;DR: In this article, the authors present an integrated global database of baseline geochemical data for monitoring the state of the environment and identifying problem areas, especially in tropical regions where a long history of chemical weathering has made the surface environment particularly fragile.

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

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.

TL;DR: The Dynamic Green Ocean Model (DGOM) as mentioned in this paper is based on the identification of key plankton functional types that need to be simulated explicitly to capture important biogeochemical processes in the ocean, and sources of information necessary to parameterize each of these processes within a modeling framework.
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.
