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.

Safer receipts without bisphenols
Researchers at EPFL have developed a new formula for thermal paper that is free of harmful bisphenols. According to toxicological studies conducted by the Ecotox Center, the wood-based substitutes used are significantly less problematic than traditional substances.

Sunscreen and bathing lakes: what happens to UV filters in Swiss lakes and experimental ponds?
UV filters from sunscreens have been detected in Swiss lakes in concentrations that in some cases exceed the provisional environmental quality criteria. In both lakes and experimental ponds, lipophilic UV filters such as octocrylene tend to accumulate at the water surface. Additional data on behaviour and toxicity in sediments is currently being collected in order to refine the quality criteria.

Sediment worms investigate the effect of wastewater on stream health
Sediment worms can be used to assess the impact of pollutants on watercourses. New studies show that treated wastewater contaminates sediments and, in some locations, can also infiltrate groundwater. A significant improvement was achieved by upgrading the facilities under investigation with an additional treatment stage.

Ecotox Centre in SRF Schweiz aktuell on the contamination of sediments
Rebecca Beauvais talks to SRF about the problem of contaminated sediments and the danger that the pollutants stored there can be remobilised again - for example during flooding or dredging.

Ecotox Centre in RTS A Bon Entendeur on tire residues
Every year, more than 10,000 tonnes of tire abrasion are generated in Switzerland, containing potentially problematic substances. Some of these compounds can end up in fruit or vegetables – a new environmental problem that raises important questions for health and ecosystems.
