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.

Louis Carles, postdoctoral scientist in the Department of Environmental Toxicology, won the award for the best live presentation during the webinar “EcotoxicoMic for Young Researchers”. He presented his work conducted in the project EcoImpact 2.0 on the impact of wastewater on stream biofilms. Louis Carles is now invited to present his work at the EcotoxicoMic 2022 Conference (Montpellier, France, 15-18 November 2022).

3rd December 2021,
Jenny Maner, PhD student in the Department Environmental Toxicology, has been awarded two prizes for the presentation of her project at recent scientific conferences: the Dr. Alain Donzel Award for best poster snapshot oral presentation at the NanoBioTech-Montreux Conference, and the SGHL Poster Award 2021 at the 19th Swiss Geoscience Meeting. Both prizewinning posters presented the RAINBOWFLOW CHIPONLINE project, the aim of which is the development of a field biosensor  for water quality monitoring using fish cell lines.

Fish are being increasingly exposed to endocrine disrupters

The ingestion of microplastics could play a significant role in exposing aquatic organisms to progesterone.

October 26, 2021,
Microplastics, owing to their chemical properties, can carry micropollutants into a fish’s digestive system where they are subsequently released through the action of its gastric and intestinal fluids. Scientists of EPFL and Eawag, working in association with other research institutes, have studied this process by looking specifically at progesterone – often pointed to as an endocrine disrupter. read more
