    Invited SPEAKERS (in presenting order)

    Valentina Bertato (EC)

    Valentina Bertato has been working in the European Commission since 2011, dealing mainly with chemicals policy. She is currently focusing on REACH restrictions for environmental risks (including microplastics, lead and PFAS) and on international work on chemicals. Her background is in environmental chemistry. Her previous working experiences are on technical and regulatory issues of chemicals, waste management and environmental management systems.

    Specifically on PFAS, she is the main author of the PFAS action plan, which is included in the European Commission Chemicals Strategy for Sustainability. She is working on the REACH restrictions on PFAS and on the proposals for listing in the Stockholm Convention. 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).
