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.

Rare earths pollute Zurich's waters
An investigation in the canton of Zurich has shown that certain rare earth elements can enter bodies of water via wastewater treatment plants in concentrations that pose a risk to aquatic organisms. These elements are gadolinium, which comes from contrast agents used in healthcare facilities, as well as lanthanum and cerium, which are used in a number of wastewater treatment plants to remove phosphorus.
