Progress in the assessment of sediment quality
Together with eight cantons, the Ecotox Centre has conducted extensive field testing to investigate the comparability of different methods for sampling and sample preparation of sediments.

A focus on communities in freshwater sediments
In April 2017, the first French-Swiss conference on communities in freshwater sediments was held in Villié-Morgon (F). A new publication summarizes the findings from the workshop.

Priorisation of pollutants for sediment monitoring in Switzerland
The Ecotox Centre has prioritised organic pollutants for sediment monitoring. The resulting list provides a basis for the sediment module of the Modular Stepwise Procedure.

Do stormwater overflows in Lake Geneva contribute to sediment pollution?
Trough the discharge of untreated rainwater, surface waters can be contaminated with heavy metals and organic pollutants. A combination of chemical and biological studies has shown that these substances in Lake Geneva reach the sediments and lead to a shift towards more resistant species.

A new system for the biomonitoring of surface waters
Biotests with whole organisms that can be used in the field provide a direct link between environmental pollution and biological effects. The Ecotox Centre has developed a new system with chironomids that measures the contamination of suspended matter.

Visitors at the Ecotox Centre
In the last months, we have been able to welcome two visitors to the Ecotox Centre in Lausanne: Dr. Leire Méndez-Fernández of the University of the Basque Country in Spain and Stéphane Pesce of the National Research Institute of Science and Technology for Environment and Agriculture (irstea) in France.

New report on measuring PCBs and dioxins in surface waters
This report evaluates the suitability of sediment analyses and of measurements with passive samplers in the water phase for localising PCB and dioxin sources. It is shown that PDMS passive samplers are well suited for this purpose.

Students learn about ecotoxicology
In which ways can earthworms assist us? What are bioassays used for? The Ecotox Centre answered these and other questions to high school pupils at the EPFL's Journées des gymnasiens.

Oligochaetes indicate sediment quality
Aquatic oligchaetes are well suited for the assessment of biological sediment quality. However, difficulties with their species determination inhibit their use as routine indicator organisms. A genetic species determination using genetic barcodes could change the situation and promote the application of the method.
