Assessing the water quality in Lake Geneva
Bioassays are also an important complement to chemical analysis in lakes when it comes to determining water quality. The use of numerous bioassays in Lake Geneva shows that fish embryo tests are particularly sensitive. Reporter tests have also provided valuable information on water pollution.

Replacement of peat in artificial soils and sediments
Last Tuesday, the Ecotox Centre hosted the kick-off meeting for the OECD project RePEAT, which seeks alternatives to peat as a source of organic matter in artificial soils and sediments.

Standardisation for sediment test with gammarids
Chemicals that can accumulate in sediments must be tested for their toxicity to sediment organisms as part of the authorisation process. The Ecotox Centre is collaborating on the OECD standardisation of the sediment toxicity test with the amphipod Gammarus sp. which is endemic to European rivers.

Ecotoxicity of munitions contaminated soil
In areas used for military purposes, the soil can be contaminated with munitions and explosives, resulting in contaminated sites with potential impacts on the environment.

Ecotox Centre in SRF Rundschau on the ecotoxicity of a controversial pesticide
The Ecotox Centre derives ecotoxicologically based limit values for plant protection products on behalf of the federal government, but only some of these values are subsequently anchored in the Water Protection Ordinance and are therefore legally binding.

Webinar: Bioassays for wastewater assessment on 18.2.2025, 14.30-16.00
A new series of webinars organised by the German Water Chemistry Society highlights the opportunities and possibilities of bioassays for assessing water quality. The Ecotox Centre is hosting the first webinar on the use of effect-based methods for wastewater testing.

Bioindicators and soil reference values for plant protection products
The Ecotox Centre is working on a comprehensive concept for monitoring pesticide residues in agricultural soils. As part of the project, we have developed a method for deriving ecotoxicological soil reference values - and have already applied it to two active substances - and have also compiled a toolbox with bioindicators for monitoring the effects of plant protection products.

Sediment quality in Swiss streams - application of the new assessment strategy
The Ecotox Centre has assessed the sediment quality in 18 streams in Switzerland on the basis of 20 prioritised pollutants. In each stream, at least one substance occurred in concentrations above the sediment quality criteria. This was the first time that the new assessment strategy was applied on a large scale.
