Sediment quality in Swiss streams - application of the new assessment strategy
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.

How can the positive effects of the WWTP upgrade be measured?
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.

Toxic effects of tire abrasion
Tire particles contain substances that have potentially estrogenic, genotoxic and bacteriotoxic effects and can be released into the environment. Using an innovative method, the researchers were able to show which substances contribute to these effects.

Sun creams and bathing lakes
In a new project, we are investigating the significance of UV filters from sun creams for the health of Swiss bathing lakes. We have already carried out bathing tests in test ponds to track the path of the substances from the skin into the water and sediment.

Info sheet on washing and cleaning agents
Washing and cleaning agents are regularly used in every household and thus end up in waste water and ultimately in sewage treatment plants. But which of the substances they contain are dangerous for the environment? And how can we protect it as well as possible - despite the use of detergents and cleaning agents? A new info sheet gives more details.
