Webinar: Bioassays for assessing estrogenic effects on 17.11.2026, 14.00-16.00
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 fourth webinar on the use of effect-based methods for assessing estrogenic effects.
Water resources are under pressure - everyone involved is becoming more aware of this from year to year. As the challenges in the water sector continue, new regulations are emerging and new testing methods are being developed and used, the ‘(Eco)Toxicological Effects’ expert group of the Water Chemistry Society's research committee invites all practitioners, authorities, researchers and local authorities involved with water and its quality to a free webinar series. Under the motto: ‘Don't be afraid of bioassays: effect-based methods in water quality assessment’, the opportunities and possibilities of bioassays for assessing water quality will be demonstrated.
The Ecotox Centre is hosting the fourth webinar on the topic
"Estrogenic effects in the new WFD – What this means for practice" (in German)
on Tuesday, 17.11.2026, 14.00-16.00
Zoom (Passcode: 785432)
Even though the forthcoming changes from the EU do not directly affect Switzerland, the principles underlying the monitoring of water bodies for estrogenic effects using effect-based methods are also of interest and relevance to experts in Switzerland.

The free webinar is open to anyone interested in learning about developments in the water sector (wastewater, surface water and drinking water) and effect-based methods. In addition to experiences, opportunities and limitations will also be discussed. We hope that there will be broad interest from authorities, district offices and local authorities. Please pass on this invitation to others.
