Biomonitoring for plant production products in Switzerland
A monitoring concept for residues in Swiss agricultural soils is currently being developed as part of the action plan for the reduction of risks and sustainable use of plant protection products. The most important steps are the development of ecotoxicological guidance values for soils and the selection of suitable biological indicators.

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.

Ecotoxicological effects of polyacrylamides and polyacrylates in agriculture
Polyacrylamides and polyacrylates can be used as soil conditioners. But since most chemical regulations do not apply to polymers, little is known about their ecotoxicological effects. A report summarises the current state of knowledge.

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.
