July 10, 2025To curb global plastic pollution and to make plastics safer and more sustainable, countries are currently negotiating a global treaty. A new study with participation from Eawag and Empa published in Nature provides a comprehensive and systematic overview of all chemicals that can be present in plastics, their properties, uses, and hazards. Moreover, the study also provides a scientific approach for identifying chemicals of concern. This allows scientists and manufacturers to develop safer plastics and policy makers to promote a non-toxic circular economy.

June 17, 2025Researchers from the Ecotox Centre, Eawag and the University of Applied Sciences Northwestern Switzerland have tested combined biological and chemical online monitoring as an early warning system at a municipal wastewater treatment plant. The system is able to detect peak loads of micropollutants in treated wastewater and identify toxic pollutants in real time. In this way, it can contribute to improving wastewater management.

June 10, 2025A sudden drop in temperature in Lake Geneva over the Whitsun weekend is leaving swimmers feeling chilly: within a few days, the surface water temperature near the city of Geneva fell by around 8 degrees. This is due to a natural phenomenon that can be observed impressively on the Alplakes platform.

May 21, 2025Tyre abrasion gets from the road into adjacent soils and affects soil organisms. A joint study by the Ecotox Centre, the aquatic research institute Eawag and the EPFL now shows that earthworms avoid soil that is heavily contaminated with tyre particles. However, the particles had no negative effects on the survival and reproduction of the animals.

May 13, 2025The year 2024 was very warm and very wet, especially in early summer. This led to a welcome replenishment of groundwater reservoirs and record hydropower production, but also to severe flooding. In Bern, the focus was on the further expansion of hydropower and the pollution of water resources by pesticides and the "eternal chemicals" PFAS.

March 26, 2025Not only are the numbers of species declining, but the composition of species communities is also changing. This is shown by a new study published in the journal “Nature”.

February 13, 2025Each year, tens of thousands of chemicals enter the market and ultimately the environment. While most of these compounds undergo safety testing before approval, their long-term effects on wildlife remain difficult to predict. To better estimate their potential threat for ecosystems, researchers at Eawag have explored biochemical signatures that indicate the level of chemical stress suffered by fish.

October 22, 2024Forest or farmland: The impact on amphipods in the groundwater is detectable, even if the groundwater extraction site is up to one kilometre away.

October 11, 2024The Swiss fisheries advisory office (FIBER) promotes sustainable fisheries through advice and training. It now has a location in French-speaking Switzerland.
