Roads as a source of pollution: new challenges
When it comes to the release of hazardous substances from roads into the environment, the focus is increasingly shifting from traditional pollutants and particles to novel, and in some cases unknown, substances. The Ecotox Centre is investigating the ecotoxicological effects of road runoff and tire wear and is attempting to identify the most critical substances.

Dynamic pollutant carriers: The quality of suspended matter in Lake Geneva
Suspended matter is an often underestimated but crucial component of aquatic environments. It binds nutrients and pollutants and transports them through the water column. A new study from Lake Geneva shows how significantly the chemical and ecotoxicological quality of these particles can change over time – and what role extreme weather events, tributaries and biological processes play in this.
