Ecotox Centre in SRF Schweiz aktuell on the contamination of sediments

Sediments can still serve as a reservoir for pollutants decades after contamination - for example in the Klingnau reservoir, which is currently being partially dredged to prevent sedimentation.

Rebecca Beauvais talks to SRF about the problem of contaminated sediments and the danger that the pollutants stored there can be remobilised again - for example during flooding or dredging.
