Additional quality criteria available
The Ecotox Centre has derived a large number of quality criteria and published them on its website. It now provides quality criteria for additional substances that have either been determined by other organisations or for which no complete data research has been carried out.

Pollutant monitoring in Swiss sediments
The Ecotox Centre has developed a strategy for assessing sediment quality. In the strategy the measured concentrations of individual substances of concern are compared with newly developed sediment quality criteria. The method has been applied to Swiss sediments giving an initial idea of their current state.

Sediment quality criteria new on website
Sediment quality criteria (SQC) can be used for sediment quality assessment by comparing environmental concentrations of the target substances with the corresponding quality criteria. The Ecotox Centre has developed SQC for 20 prioritised substances or substance classes.

Sensitive bioassays on HPTLC plates
The Ecotox Centre has advanced an innovative method to sensitively determine the toxicity of unknown mixtures and unmask the responsible substances. This is not only interesting for food safety, but also for environmental analysis.

New large-scale project on the risk assessment of chemicals
Together with partners from Switzerland and the EU, the Ecotox Centre compares the prospective and retrospective risk assessment of pesticides and further develops assessment approaches and concepts. Further activities concern the assessment of substance mixtures and the monitoring of endocrine disruptors and perfluorinated chemicals in the environment.

Elevated ecotoxicological risks through pyrethroid and organophosphate insecticides
Pyrethroid and organophosphate insecticides were detected in small streams at all 17 sampling sites that were investigated during the 2019 NAWA monitoring campaign. Although the measured concentrations were mostly low, they pose a significant risk to aquatic organisms.

Biomarkers in chironomids for the detection of sediment quality
By measuring gene expression, effects can be detected that do not directly lead to death , but can trigger an effect-specific stress response and thus cause long-term damage to the organism.
