16.08.2017 | Young Water Researchers' Symposium in Aachen - Call for Abstracts

We are pleased to invite you to attend and present at the first annual Young Water Researchers' Symposium (YoWaReS) in Aachen on Friday November 24, 2017 in HKW 1 (Toaster building), Wüllnerstr. 1, 52062 Aachen.

The symposium's topics cover:
•    Water quality and treatment
•    Organic micropollutants in the environment: Fate, speciation and bioavailability in water, soil and sediment
•    Contaminated sediments in aquatic systems - resuspension, transport, distribution and its modeling
•    Water-related innovations and resource economics

Our aims are to:
•    Connect young researchers and professionals in the area of water-related research.
•    Provide a platform to present yourself and to enable in-depth discussions in a relaxed environment.
•    Exchange ideas and perspectives from different disciplines and several European countries.

Are you a PhD or advanced master's student interested in water research?
Do you want to get connected?
Are you looking for our best presentation/poster award?
Then YoWaReS is the place to be!

Don't miss the submission deadline for your abstract (max. 10000 characters) on September 30, 2017.
Registration deadline is November 10, 2017. Contribution towards expenses is 15 €.

01.08.2017 | Projekt UBA-COMBITOX geht an den Start

Mischen impossible? – Umweltforscher prognostizieren Effekte von Spritzfolgen und Tankmischungen von Pflanzenschutzmitteln auf die biologische Vielfalt in der Agrarlandschaft. In der landwirtschaftlichen Praxis werden Pflanzenschutzmittel, anders als es im Zulassungsverfahren bewertet wird, nicht einzeln und in großem zeitlichem Abstand angewendet. Vielmehr erfolgt die Ausbringung und der Abbau komplexer Mischungen der Pflanzenschutzmittelsubstanzen im Freiland zum Teil in enger zeitlicher Abfolge. Das komplexe Projekt „COMBITOX“, das durch das Umweltbundesamt gefördert wird, geht folgenden Fragen nach:

•    Wie können Effekte von Mischungen auf chronische Endpunkte aus Labortests und auf aquatische und terrestrische Lebensgemeinschaften prognostiziert werden?
•    Wie lassen sich die realen, sehr komplexen Behandlungsregimes beschreiben und klassifizieren und für protektive Risikobewertungen verwenden?
•    Wie ändert sich der Abbau von Fremdstoffen in multiplen Expositionsszenarien?
•    Welche Mechanismen sind bestimmend für das Risiko und wie lassen sich diese in anwendbare Modelle übersetzen?

Beteiligt an diesem Projekt sind das UFZ - Helmholtz-Zentrum für Umweltforschung GmbH, Department System Ökotoxikologie, Leipzig in der Koordination und unser Institut für Umweltforschung (Lehrstuhl für Umweltbiologie und-chemodynamik).

16.05.2017 | Successful NORMAN WG2 meeting

The NORMAN Working Group (WG) 2 on Bioassays and biomarkers in water quality monitoring, in partnership with the Institute of Environmental Research, RWTH Aachen University, hosted a very successful meeting last month (26.04.2017). The scientific committee of the meeting included Prof. Dr. Henner Hollert (RWTH), Dr. Sarah Crawford (RWTH), Dr. Valeria Dulio (INERIS), and was organized with the help of several ESA student volunteers. The focus of the meeting was on “the integration of bioassays and biomarkers in water quality monitoring and neurotoxicity assessment”. The overall aim of the activity is to contribute towards the implementation of bioassays within the Working Group “Chemicals” of the CIS (common implementation strategy) of the Water Framework Directive (WFD) on EU level. Highlights of speakers included Dr. Jessica Legradi (Vrije Universiteit Amsterdam, NL), Prof. Dr. Markus Hecker (University of Saskatchewan, CAN), Dr. Sebastian Buchinger (BfG, Fedeal Hydrological Institute, GER), Dr. Cornelia Kienle (Ecotox Centre, Eawag, CH) and Prof. Dr. Beate Escher (UFZ, Center for Environmental Research, GER). Talks and discussions touched on the challenges and integration of neurotoxicity testing as well as the application of bioanalytical tools to address emerging pollutants in water. From the discussions of this meeting, a draft of a common position within the wider scientific community on how to use bioassays and biomarkers for water quality monitoring will be produced (i.e., methodology to define effect-based trigger values; recommendations for a common battery of bioassays; quality/performance criteria for the benchmarking of bioassays).
A follow-up meeting for the NORMAN WG2 will be hosted June 20-22 at the Swiss Ecotox Centre (Eawag) in Dübendorf, CH on the “Estrogen Monitoring final project meeting” (Moderated by: Robert Kase and Mario Carere), “Estrogen Monitoring recommendation workshop” together with NORMAN and SOLUTIONS Networks (Moderated by: Valeria Dulio) and the “Effect-based trigger value (EBT) discussion workshop” (Moderated by: Beate Escher, Robert Kase, Henner Hollert).
