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.

Evidence Fitness
Methods (brief)
Acetonitrile/zinc sulfate extraction and WAX SPE; UPLC-MS/MS negative ESI triple-quadrupole MRM (PDF pp.4 to 5).
Targets as printed or genericized: Occurrence table: PFBS; PFNA; PFOS; PFDA. Full panel and transitions require absent supplementary Table S1 (PDF pp.4 to 5,10 to 11).
Limitations
Only selected farms with detectable results are displayed in Table 4, so this table is not the full farm inventory. Complete target panel cannot be verified without the local supplement. No substitution of ND or trace results. No conversions, risk thresholds, representativeness claims, or safety conclusions are added.
Provenance notes
Local staged PDF copied unchanged. DOI checked in deposited PDF against MANIFEST; no external resolution attempted. Title and citation metadata checked against the PDF first page.
See the cell MISMATCHES.csv for unresolved discrepancies. The legacy MANIFEST analyte field is discovery metadata, not an audited target list.
