Environmental Risk Assessment

Environmental risk assessment of chemicals tries to identify substances that cause unacceptable damage and detrimental effects on aquatic organisms and ecosystems. We support evidence based environmental risk assessment of chemicals by advancing the understanding of the underlying ecotoxicological processes. We also develop models which capture this knowledge about processes and inter-relationships and make it available for risk managers and practitioners.

Projects

• Improving the definition of water quality criteria: linking organism recovery times to mechanism of action and acute-to-chronic ratios
  
• Toxicokinetic and toxicodynamic models in aquatic ecotoxicology for a mechanistic link between bioconcentration and effect
  
• Mechanistic effect models for ecological risk assessment of chemicals
• Risk assessment of transformation products
• Integration of internal metabolites in effect modelling of insecticides in Daphnia magna
