Brief Abstract: This webinar will be of interest to all toxicologists who perform toxicological risk assessments. The regulation of per- and poly-fluoroalkyl substances (PFAS) is a growing topic of interest, due in part to the widespread detection of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). Some believe the most appropriate approach to PFAS regulation or consideration of their potential risks is to lump together both polymeric and non-polymeric categories, treating them as if they were a single class of substances. Fluoropolymers become aggregated into the highly broad PFAS classification without regard to distinct characteristics that qualify them as meeting the globally accepted criteria for Polymers of Low Concern (OECD, 2009; BIO by Deloitte, 2015).

A new paper, in review for publication in Integrated Environmental Assessment and Management (IEAM), is intended to drive further clarity on the broad group of chemistry known as PFAS. The authors conducted a thorough review of the regulatory history of the hazard assessment of polymers and non-polymers, as well as the scientific foundation for the resulting paradigm ("polymers of low concern"), and they articulate a clear and compelling scientific basis for segregating fluoropolymers from other PFAS. Separation of fluoropolymers from the larger list of thousands of substances grouped into five different classes of PFAS is based upon the authors' demonstration that fluoropolymers constitute a distinct class within the PFAS group and, therefore, should be considered separately for hazard assessment or regulatory purposes. The paper further establishes that grouping fluoropolymers with all classes of PFASs for "read-across" or structure-activity relationship assessment is not scientifically appropriate, when a complete, good quality data set exists, as it does for fluoropolymers.
