Webinar: Bioassays for assessing surface water quality, 28.10.2025, 14.30-16.00
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 also contributing to the second webinar on the use of effect-based methods for assessing suface water quality.
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 also contributing to the second webinar on the topic
"Quality monitoring in surface waters – possibilities and limitations of effect-based assays"

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.
