She is closely following all developments related to PFAS in the different EU legislations.
Scott Mabury
Professor of Environmental Chemistry & Vice-President of Operations and Real Estate Partnerships, University of Toronto
Exploring the Fate, Disposition, and Persistence of organofluorine chemicals has been the major areas of research focus since ~1990. We use a suite of “reactors” including rats, smog chambers, soils, sunlit water, fish, etc to explore kinetics and reaction pathways with particular focus on reactive intermediates with potential for toxicity. We synthesize what we need to for identification and further experimentation and frequently develop specialized analytical methods. Objective is to better understand chemical pollution while also using these “pollutants” as chemical probes to enhance our understanding of the natural world. Awards include the CIC Environment R&D award, the 2015 ISI Most Highly Cited (Ecology & Evolution), and multiple teaching awards (LIFT, OCUFA, A&S); current H-factor (72 WOS; 75 Scopus). Other passions include building soil health aka farming (corn, canola, soybeans, wheat, adzuki beans, hay).
