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.

The smallest of all plastic particles have remained largely unexplored until now, because they could not be detected in the environment. Now researchers at Eawag show: Nanoplastics stick to slimy biofilms, which can for example be found on stones in streams or rivers. When freshwater snails feed on the slime, the nanoplastics are taken up.

As part of a new national research programme that aims to replace animal experiments in research, the National Science Foundation is supporting a project at Eawag. This opens up new possibilities for determining the toxicity of chemical substances based solely on tests with cultured cells and computer models. Animal experiments could thus be replaced.
