Ecotoxicity of tire wear particles
Jedes Jahr gelangen mehrere Tausend Tonnen Reifenabrieb in die Umwelt, die aus einem komplexen Gemisch von Gummipartikeln und Strassenmaterial bestehen und mit zahlreichen Schadstoffen belastet sind. Das Oekotoxzentrum arbeitet daher in einem neuen Projekt daran, die Bioverfügbarkeit und Toxizität von Reifenabrieb besser zu verstehen.

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
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
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.

Assessment of sediment quality in artificial canals in Valais
Ecotoxicological bioassays and the assessment of invertebrate benthic communities complement physico-chemical analyses when assessing sediment quality. The sediment quality in three artificial channels in the Valais was severely affected.

Fungicidal azoles cause concern
In Switzerland, these substances are detected in most samples from water, sediment, soil and organisms. However, a lack of toxicity data for many azoles makes it difficult to assess the risk they pose.

Few estrogens in Europe's rivers
Studies with biotests have shown it: Most European watercourses do not contain estrogenic substances in critical concentrations. Switzerland has also participated in the huge monitoring project initiated by the Ecotox Centre. All Swiss samples were harmless.
