Summary
Community near an abandoned paper mill. Household water samples after mitigation are distinct from historical municipal-well maxima and from serum concentrations.
Key numbers
Source-reported values checked against the cited page of the filed PDF. Values are reported as printed, without conversion. These are selected records, not an exhaustive transcription.
| analyte | value | unit | basis | source location | limits and qualifiers |
|---|---|---|---|---|---|
| PFBS | ≤13 | ng/L | current public-water samples, reported upper concentration | PDF p6, section 3.2 Water | Sample-specific reporting limits, PDF p4; second laboratory RLs/MDLs at least ⇐5 ng/L as printed, with analyte details in unstaged Table S3. Do not impose a shared threshold. |
2 further transcribed values remain under review and are not shown.
Evidence Fitness
Source classification: primary_measurement. MANIFEST tier: PRIMARY. This is a selected, bounded transcription, not an exhaustive extraction of every result in the paper. Each selected number has its own PDF page or table locator. Values for different matrices, isomers, statistics and aggregate assays are not interchangeable.
Methods (brief)
Household tap-water LC-HRMS in the first laboratory and SPE-LC-MS/MS in the second, PDF p4. Target panels and reporting rules differ across laboratories.
Detection limits and censoring: Sample-specific reporting limits, PDF p4; second laboratory RLs/MDLs at least ⇐5 ng/L as printed, with analyte details in unstaged Table S3. Do not impose a shared threshold.
Limitations
- ABSTRACT_METHOD_SCOPE: Abstract broadly describes LC-MS/MS. Comparison: Tap-water Methods include both LC-HRMS and LC-MS/MS laboratories. Locator: PDF p1 abstract versus p4 Methods. Preserve assay distinction and laboratory-specific reporting limits.
- ANALYTE_NAME_ABBREVIATION: Body expands PFHxS as a pentane sulfonic acid and PFPeA as butane sulfonic acid. Comparison: Acronyms and elsewhere-used names differ. Locator: PDF p6 statistical-analysis paragraph. Do not adopt incorrect expanded names; occurrence rows preserve acronyms.
Provenance notes
Citation metadata verified against PDF p1, title, author byline, journal citation or masthead, and DOI.. Article DOI appears in the supplied PDF and matches the MANIFEST case-insensitively. Original file: 2025_Bauer_elevated-per-and-polyfluoroalkyl-substances-pfass.pdf. SHA-256: 6645b3b6900afe1067ec5f03ff08cde1f3751095e99e0859fca0e8b509c8569a. Original MANIFEST remains in the copied packet; discrepancies are listed without modifying it. Commercial analyte synonyms, instrument brands and manufacturer names are generalized in authored index prose.
