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.

Award for excellent alternatives for animal trials

Toxicity tests are currently still carried out mainly on livestock. Within the context of environmental risk assessment, this is done most commonly on fish. An alternative method developed by Eawag researchers is currently overcoming crucial hurdles to its widespread use in practice. Thanks in part to the persuasive efforts of the scientists involved.              read more

2020 Europe Award Winners

A pipeline was developed to process extremely heterogenous data sets and assess molecular mechanisms of nanotoxicity

Rifcon Best Publication Award

Michael Burkard is a young researcher working at Eawag on the caLIBRAte-project. The aim of the project was to test a number of tools for the risk assessment of nanomaterials. The focus of Eawag was to evaluate the use of innovative methods, such as the Omics technologies, in order to improve risk assessment. In the rewarded work, a pipeline was developed to homogenize existing data sets and to assess toxicological response patterns from nanomaterials. read more
