Perfluorooctane Sulfonate in Oysters, Crassostrea virginica, from the Gulf of Mexico and the Chesapeake Bay, USA
Abstract
Concentrations of perfluorooctane sulfonate (PFOS), a metabolite of several sulfonated perfluoroorganic compounds, were measured in oysters collected from 77 locations in the Gulf of Mexico and Chesapeake Bay of the United States. PFOS was detected in oysters collected from 51 of the 77 locations at concentrations ranging from < 42 to 1,225 ng/g on a dry weight basis. This study provides baseline data for future monitoring programs to examine long-term trends in concentrations of PFOS.

Previous studies on PFAS in the Texas Gulf Coast have documented PFAS occurrence in surface water and biota, but sediment occurrence remains understudied and comprehensive watershed-scale monitoring is limited.

Knowledge of PFAS occurrence in the Lavaca region is limited to quarterly drinking water monitoring from 2023 to 2025 and data from oysters collected in 1996.

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.
