Alexandra Kroll

Alexandra Kroll is a Researcher at the Ecotox Center (Eawag) since 2019, specializing in Environmental Risk Assessment and Ecotoxicology. Her work focuses on micropollutants, nanoparticles, microplastics, and pesticides in aquatic systems, with a particular emphasis on regulatory frameworks and chemical safety.

• PhD in Nanotoxicology (University Hospital Münster, 2006-2009)
• Postdoctoral research at Eawag (2010-2016)

Her research interests span environmental risk assessment of pharmaceuticals, nanoparticle interactions with biofilms, microplastic effects on freshwater organisms, and pesticide regulation. Recent projects include evaluating UV-filters in Swiss lakes and deriving environmental quality standards.

Key scientific contributions involve flow cytometry for biofilm analysis, pH-specific aquatic thresholds, and landscape-based ERA frameworks. She has been recognized with the SNSF Ambizione Fellowship (2010-2016) for her nanotoxicology research.
