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.

Weniger Pflanzenschutzmittel für Thurgauer Gewässer

In the canton of Thurgau, experts from the offices are working with farmers to reduce the pollution of watercourses with pesticides. Bioassays with water and sediment samples show that the ecotoxicological status of streams is currently significantly impaired.

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.

Info sheet on PFAS in the environment

Info sheet on PFAS in the environment

Per- and polyfluorinated alkyl substances (PFAS) are very stable and accumulate worldwide in the environment and in organisms. A new info sheet gives information on their occurrence, their toxicity and the regulatory context.

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.

Detection of pollutants in food packaging

Detection of pollutants in food packaging

Food packaging contains complex mixtures of chemicals. A new method can sensitively measure their toxicity and help to find out which substances are responsible for the toxicity.

TKTD-modelling for dummies

TKTD-modelling for dummies

A milestone has been reached by processing one of the TKTD models for the use of practitioners without modelling experience. With the GUTs model, the mortality can be predicted for a given concentration curve of a chemical.

Invertebrate and microbial communities in contaminated river sediments

Invertebrate and microbial communities in contaminated river sediments

The river sediments of Ardières and Tillet are both polluted with complex substance mixtures. The effect of the contamination with PCB on the oligochaete communities was clearly visible. The effect of the contamination on microbial communities was harder to assess because microbes are influenced by a multitude of environmental factors.
