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.

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.

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.

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.

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.

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.
