Behaviour, speciation and toxicity of metal oxide nano particles in aquatic toxicity testing
The use and production of nano particles is increasing steadily, but the knowledge of their environmental behaviour and toxicity is still very scarce. A major drawback in studies that investigate the toxicity of nano particles is the difficulty in determination of actual exposure concentrations, which is caused by e.g. the dynamics of aggregation and dissociation in solutions. The project aims on the investigation of the dynamics and uptake kinetics of different forms of zinc oxide nano particles with the help of ultracentrifugation, ultrafiltration, advanced ICP-MS measurements and Absence of gradients and Nernstian equilibrium stripping methodology (AGNES).
