Dynamics of the metal sink/source function of aquatic ecosystems
07 / 2006 - 10 / 2008
The reactivity and spread of metal species in environmental aquatic bodies are to a large extent governed by physicochemical binding to colloids and sediments. The pertaining accumulation/release of metal species is especially important under conditions of high metal loads and is known as the sink/source function of the ecosystem. The major goal of the project is to quantitatively characterize the kinetics of binding/release of metal ionic species by/from natural colloidal complexing agents, including biogels. The results will serve as the basic molecular input parameters in the modelling of the effective transport and spread of metallic pollutant species following an incidental high load.
