How polluted are our surface waters with toxicants such as pesticides? What are impacts on the biodiversity and the functions of the ecosystem? Can we quantify combined effects of toxicants and environmental factors such as climate change? Which remediation measures are efficient?



The Department of System-Ecotoxicology identifies relevant effect mechanisms of toxicants. We apply this knowledge to uncover the effects of chemicals on indivuduals, populations and ecosystems. From this we develop methods to monitor toxicant effects (SPEAR) and approaches to predict their ecological impact.

Our knowledge and tools support scientists, public authorities and politicians to develop a sustainable management of toxic substances.
