PFAS in Swiss sediments

PFAS in Swiss sediments

Per- and polyfluorinated alkyl compounds (PFAS) are very stable in the environment and are therefore detected almost everywhere. A new study investigates the occurrence of PFAS in Swiss sediments.

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.

Biomonitoring for plant production products in Switzerland

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

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

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.
