An example that meets this need is the definition by the U.S. Environmental Protection Agency of PFAS as {"}per- and polyfluorinated substances that structurally contain the unit R-(CF2)-C(F)(R1)R2. Both the CF2 and CF moieties are saturated carbons and none of the R groups (R, R1, or R2) can be hydrogen{"}. Adoption of this definition, or one like it, would place future technical and regulatory discussions of the environmental impacts of organo-fluorine compounds on a sounder technical footing by focusing PFAS discussions and regulation on long-chain perfluoroalkyl sulfonic acids and perfluoroalkyl carboxylic acids.
