How do aquatic organisms respond to stress?

We investigate how freshwater organisms respond to chemical exposure and other stressors in their environment. In particular, we explore adaptive and toxicological response pathways and develop conceptual and computational models to support knowledge-based risk assessment.

Ozonation is an established treatment process to remove micropollutants from wastewater. However, since unstable toxic reaction products can be formed in the process, biological post-treatment is necessary. Results from the Ecotox Centre and Eawag show how well different post-treatment methods reduce ecotoxicological effects. The combination of ozonation and activated carbon proved to be the most effective.
