Abstract

The present survey examines the trophodynamics of a suite of 19 perfluoroalkyl substances (PFASs) in a temperate macrotidal estuary (Gironde, SW France). Across the 147 biota samples (18 taxa) collected, perfluorooctane sulfonate (PFOS), perfluorooctane sulfonamide (FOSA), and C 8 –C 14 perfluoroalkyl carboxylates (PFCAs) were the most-recurrent analytes. ΣPFASs ranged between 0.66–45 ng per g of wet weight of the whole body. Benthic organisms had relatively high ΣPFASs compared to demersal organisms and displayed specific composition profiles with higher relative abundances of C 8 and C 9 PFCAs. Trophic magnification factors (TMFs) were determined through the use of linear mixed effect models including censored data, thereby considering data below detection limits as well as the interspecific variability of δ 15 N and PFAS levels (random effects). TMFs were almost consistently >1 in the benthic food web as well as when considering all data pooled together, providing evidence for the biomagnification of several PFASs in estuarine environments. In addition, in contrast with previous observations, TMFs determined in the estuarine benthic web were found to significantly decrease with increasing chain length for C 8 –C 14 PFCAs and C 6 –C 8 perfluoroalkyl sulfonates. This suggests that PFAS chemical structure might not be necessarily predictive of TMFs, which are also influenced by the trophic web characteristics.

  • Munoz et al. (2017) found PFOS, perfluorooctane sulfonamide (FOSA), and C8-C14 PFCAs were the predominant PFAS in the biota.

    “they found PFOS, perfluorooctane sulfonamide (FOSA), and C8− C14 PFCAs were the predominant PFAS in the biota.”

    From Per- and polyfluoroalkyl substances (PFAS) in the marine environment: An overview and prospects (2025) · cites this paper as Munoz et al., 2017

    Section 3.3 (page unavailable) reports that PFOS and FOSA had the highest detection frequencies in biota and that C9–C13 PFCAs were detected in most samples. But 'predominant' implies abundance: the same section says PFOS was generally dominant, while C11–C14 PFCAs were less prominent in pelagic organisms. It does not support describing the entire C8–C14 PFCA range as predominant by abundance. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
