Comment on Proposed Restriction of PFAS May 30, 2023 Japan Fluoropolymers Industry Association (JFIA) We, Japan Fluoropolymers Industry Association (JFIA), think that fluoropolymers should be distinguished from the proposed restriction of PFAS (Per- and polyfluoroalkyl substances), which collectively regulates more than 10,000 of organofluorine compounds (PFAS) on the grouping basis.

KEYWORDS: piezoelectric material, mechanochemistry, ball milling, PFAS, sediment INTRODUCTION Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals used since the 1940s.1 Their ubiquitous presence in the environment, significant toxicity, and persistence have garnered rapidly growing public concerns.2 Even so, the production and use of legacy PFAS, such as perfluorooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA), have not been eliminated globally.3 Some alternative PFAS being manufactured have already shown toxicity and are facing forthcoming bans.4,5 Therefore, the cycle of "alternative development-assessment-elimination" is a long-lasting effort that will lead to the continuous production of obsolete PFAS stockpiles.

For this inspection, I operated as the lead inspector.
