The Ecotox Centre has assessed the sediment quality in 18 streams in Switzerland on the basis of 20 prioritised pollutants. In each stream, at least one substance occurred in concentrations above the sediment quality criteria. This was the first time that the new assessment strategy was applied on a large scale.

Numerous biotests and biomarkers are used to assess the impact of the upgrade of the Falkenstein WWTP on the water quality of the Dünnern. The quality of communities and the occurrence of antibiotic resistance are also taken into account. The measurements prior to the upgrade show clear differences between the water quality upstream and downstream of the WWTP outflow. Significant improvements are expected as a result of the upgrade.

Last week, we welcomed around 20 representatives of leading tire manufacturers for a two-day training course on ecotoxicology.
