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

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.

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.

Assessment of sediment quality in artificial canals in Valais

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

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.
