Biota-Sediment Accumulation Factors for Per- and Polyfluoroalkyl Substances.

ABSTRACT: Per- and polyfluoroalkyl substances (PFAS) are widely used in commercial products such textiles, firefighting foams, and surface coatings across the globe and some PFAS are known to be bioaccumulative in aquatic species. The ultimate sink for numerous anthropogenic chemicals is the sediments in lakes, rivers, and oceans. To understand the relationship between sediment and aquatic species, a literature search was performed and biota-sediment accumulation factors (BSAFs) data for 17 taxonomic classes were assembled. The carbonyl and sulfonyl PFAS classes were relatively data rich whereas phosphate (no measurements), ether (one chemical), and fluorotelomer (limited number of chemicals) PFAS classes were data poor. Taxonomic classes of Teleostei and Clitellata had the largest BSAFs whereas Mag
