Oligochaetes indicate sediment quality
Aquatic oligchaetes are well suited for the assessment of biological sediment quality. However, difficulties with their species determination inhibit their use as routine indicator organisms. A genetic species determination using genetic barcodes could change the situation and promote the application of the method.

Bioassays assess ozonation and post-treatment of wastewater
Ozonation is an established treatment technology to remove micropollutants from wastewater. However, labile toxic reaction products may be formed during ozonation. Therefore, a biological post-treatment step is needed. Using bioassays, the Ecotox Centre has assessed how efficient ecotoxicological effects are reduced by ozonation in combination with various post-treatment technologies.

Neonicotinoids - harmful to soil organisms?
The neonicotinoids imidacloprid and clothianidin were detected in soil of sugar beet, wheat and corn fields as well as in soil of ecological compensation areas. The toxicity of the substances to the beneficial springtail was determined. It was shown that the measured concentrations represent a potential risk for springtail health.

Risk assessment of transformation products of pharmaceuticals
Not only pharmaceuticals but also their transformation products may pollute our surface waters. However, the assessment of their ecotoxicological risk is difficult because data on their ecotoxicity are often missing. In a case study, the Ecotox Centre compares the existing assessment methods.

Estrogens from agriculture
A joint project by Agroscope and the Ecotox Centre investigates the discharge and fate of natural estrogens from agriculture. The aim is to quantitatively assess the occurrence, the behaviour and the importance of estrogens from agriculture for surface waters in Switzerland. The project is financed by the Federal Office for the Environment.
