A Dominating Role of Functional Groups in Short-Chain Per- and Polyfluoroalkyl Substance (PFAS) Accumulation by Fruiting Plants

Many per- and polyfluoroalkyl substances (PFAS) have either carboxylic acid or sulfonic acid as their polar functional group. Studies to date have consistently shown that accumulation of short-chain PFAS containing sulfonic acid in fruits is much more limited than those with carboxylic acid, but …
