Distribution of Colloidal trace metals in the San Francisco Bay estuary
TL;DR: In this paper, the size distribution of trace metals (Al, Ag, Cd, Cu, Fe, Mn, Ni, Sr, and Zn) was examined in surface waters of the San Francisco Bay estuary.
Journal ArticleDOI
Speciation of heavy metals in environmental water by ion chromatography coupled to ICP–MS
TL;DR: A new chromatographic procedure based on a synthetic hydrophilic quaternary ammonium anion exchanger in combination with nitrate as a strong eluent anion, and gradient elution provided high separation selectivity and a large analytical window, allowed the method to be successfully applied to different environmental research areas.
Journal ArticleDOI
Composition and cycling of colloids in marine environments
Laodong Guo,Peter H. Santschi +1 more
TL;DR: In this paper, the authors focus on recent developments on isotopic and elemental composition of colloids which allow organic matter cycling in marine environments to be constrained, and discuss sources and turnover rates of organic matter in the ocean, importance of benthic boundary layer processes in the cycling of DOM, changes in the paradigms of marine organic matter, and research needs for a better understanding of the biogeochemistry of marine colloids.
Journal ArticleDOI
Comparison of the linear Van den Berg/Ružić transformation and a non-linear fit of the Langmuir isotherm applied to Cu speciation data in the estuarine environment
TL;DR: In this paper, two methods for the estimation of the complexation parameters according to the Langmuir isotherm are compared: the linear transformation of Van den Berg/Rǔzic and the non-linear method according to Wilkinson.

Predicting animal cadmium concentrations in lakes
Landis Hare,André Tessier +1 more
TL;DR: In this paper, the free-ion activity model was used to predict the toxicity of metals in aquatic organisms, and the results suggest that the model would provide an effective theoretical framework for the use of animals as indicators of metal contamination in nature.

Journal ArticleDOI
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.
Journal ArticleDOI
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.

Watson,Dieter Wolf-Gladrow +23 more
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.
