Abstract

We aimed to investigate the role of indoor office air on exposure to polyfluorinated compounds (PFCs) among office workers. Week-long, active air sampling was conducted during the winter of 2009 in 31 offices in Boston, MA. Air samples were analyzed for fluorotelomer alcohols (FTOHs), sulfonamides (FOSAs), and sulfonamidoethanols (FOSEs). Serum was collected from each participant (n = 31) and analyzed for 12 PFCs including PFOA and PFOS. In air, FTOHs were present in the highest concentrations, particularly 8:2-FTOH (GM = 9920 pg/m(3)). FTOHs varied significantly by building with the highest levels observed in a newly constructed building. PFOA in serum was significantly correlated with air levels of 6:2-FTOH (r = 0.43), 8:2-FTOH (r = 0.60), and 10:2-FTOH (r = 0.62). Collectively, FTOHs in air significantly predicted PFOA in serum (p < 0.001) and explained approximately 36% of the variation in serum PFOA concentrations. PFOS in serum was not associated with air levels of FOSAs/FOSEs. In conclusion, FTOH concentrations in office air significantly predict serum PFOA concentrations in office workers. Variation in PFC air concentrations by building is likely due to differences in the number, type, and age of potential sources such as carpeting, furniture, and/or paint.

  • Children are particularly vulnerable to PFAS exposure due to their developing organs, higher metabolic rates, greater intake of air, food, and water per unit body weight, and behaviors such as hand-to-mouth contact that increase exposure risk.

    “Children are particularly vulnerable to PFAS exposure due to their developing organs, higher metabolic rates, greater intake of air, food, and water per unit body weight, and behaviors such as hand-to-mouth contact that increase exposure risk.”

    The Introduction lists general PFAS exposure pathways, and the Discussion focuses on indoor-air exposure among office workers. Our copy does not address whether children are particularly vulnerable or link their exposure risk to developing organs, metabolic rates, intake per body weight, or hand-to-mouth behavior (searched for children and hand-to-mouth exposure). (LLM, conf=0.76)

  • Biomonitoring data show that young children frequently have higher serum PFAS concentrations than adults, particularly in environmentally contaminated areas.

    “Biomonitoring data show that young children frequently have higher serum PFAS concentrations than adults, particularly in environmentally contaminated areas [5,42,43,60].”

    From Exposure to Per- and Polyfluoroalkyl Substances (PFASs) in Healthcare: Environmental and Clinical Insights (2025) · cites this paper as [43]

    The Results (Serum Concentrations; page unavailable) report PFAS measurements in office workers, while the Discussion (page unavailable) compares those measurements with U.S. general-population trends. Neither passage compares young children with adults or addresses environmentally contaminated areas. Searches for child–adult serum comparisons and contaminated areas found no passage making the claimed point. (LLM, conf=0.76)

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.
