Sediment quality criteria new on website

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.

Biomarkers in chironomids for the detection of sediment quality

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.

Expert report: Strategy for assessing sediment quality in Switzerland

Expert report: Strategy for assessing sediment quality in Switzerland

Sediments play a crucial role for surface water quality. However, until now there has been no uniform method for the cantons to monitor sediment quality. On behalf of the Federal Office for the Environment, experts from the Ecotox Centre have drawn up a proposal on how sediments in Switzerland should be sampled, processed and assessed.

Tire wear as a source of pollutants

Tire wear as a source of pollutants

Although large quantities of tire wear are released into the environment, we still know little about the toxicity of those small particles. The particles contain not only rubber, but also numerous metals and organic substances. Researchers from the Ecotox Centre, EPFL and Eawag are currently investigating whether these substances are bioavailable and what toxic effects they may have.

Project on rodent poisons

Project on rodent poisons

Anticoagulants are highly toxic chemical substances that are used to control harmful rodents such as mice and rats. In a new project the Ecotox Centre aims to assess the environmental contamination with anticoagulants in Switzerland.
