Ecotox Centre at EPFL - Interview with Christof Holliger
Christof Holliger, Professor of Environmental Biotechnology at EPFL, has been closely involved with the Ecotox Centre since it was founded in 2008, initially as part of the direction and the strategic steering committee and later as the representative of EPFL on the host institute council. He retired at the end of February 2025. Here he looks back.

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.

Successful dissertation
We congratulate Ali Kizgin on the successful defence of his dissertation. Over the past four years, Ali has been researching at the Ecotox Centre a key challenge in wastewater management - namely the early detection of pollution events using online biomonitoring.

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.
