Ian T. Cousins - Department of Environmental Science at University of Stockholm - will be speaking on the topic :Strategies for Grouping PFAS for Chemical Assessment: An Update." more information...
In April 2020, my colleagues and I published a paper outlining grouping strategies for per- and polyfluoroalkyl substances (PFAS) that could be applied in chemical assessment. Many academic and regulatory scientists believe that grouping strategies are needed to make the task of assessing the many thousands of PFAS on the global market more manageable. Industry scientists, however, tend on the whole to oppose any grouping strategies for PFAS and favour instead a chemical-by-chemical assessment approach based on risk assessment. In this talk, I will provide an update on the work presented in our 2020 paper with more approaches presented for grouping PFAS for risk assessment. I will also review grouping strategies based on the intrinsic properties of the PFAS (e.g. persistence, bioaccumulation potential, toxicity, and mobility). The pros and cons of the various grouping approaches presented will be discussed.
