PFAS in Swiss sediments

PFAS in Swiss sediments

Per- and polyfluorinated alkyl compounds (PFAS) are very stable in the environment and are therefore detected almost everywhere. A new study investigates the occurrence of PFAS in Swiss sediments.

Strategy for assessing sediment quality in Switzerland

Strategy for assessing sediment quality in Switzerland

After 6 years, the assessment concept for sediment quality in Switzerland is in the home straight. In addition to a harmonised method for sampling and sample preparation, a list of substances for regular sediment monitoring has been developed, as well as sediment quality criteria and an evaluation system.

Genetic barcodes for sediment assessment

Genetic barcodes for sediment assessment

The sediment quality in lakes and rivers can be assessed by studying the composition of oligochaete communities present in situ. The use of high-throughput sequencing allows the reliable identification of oligochaetes and makes this bioindication method accessible.

Ecotoxicity of tire wear particles

Ecotoxicity of tire wear particles

Every year, several thousand tonnes of tire wear particles, consisting of a complex mixture of rubber particles and road material, are released into the environment and are contaminated with numerous pollutants. In a new project, the Ecotox Centre is working to improve our understanding of the bioavailability and toxicity of tire wear particles.
