Priorisation of pollutants for sediment monitoring in Switzerland

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?

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

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.

New report on measuring PCBs and dioxins in surface waters

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.

Oligochaetes indicate sediment quality

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.
