Marion Junghans

Dr. Marion Junghans is a leading researcher at the Swiss Centre for Applied Ecotoxicology (Ecotox Centre), affiliated with Eawag and EPFL. Since 2010, she has focused on risk assessment of micropollutants in water, predictive mixture toxicity modeling, and implementation of OECD aquatic ecotoxicology test methods.

• Specializes in pesticide risk assessment for aquatic ecosystems
• Contributes to updating Swiss water quality standards
• Active in European chemical risk assessment collaborations

Her research emphasizes realistic exposure scenarios, sediment and soil ecotoxicology, and environmental policy frameworks. Recent publications analyze time-variable pesticide exposures, UV-filter toxicity in freshwater, and PFAS contamination in Swiss streams.

Key projects include the ConSoil framework for agricultural soil residues, NAWA SPEZ water quality campaigns, and sediment risk assessment guidelines. She also designs continuing education courses in ecotoxicology and serves on advisory boards for environmental regulation.
