Evidence Fitness
Methods (brief)
LC-MS/MS with isotope-labeled internal standards; extraction and solid-phase cleanup (PDF pp.3 to 4).
Targets as printed or genericized: PFBS; PFPeS; PFHxS; PFHpS; linear and branched PFOS; PFHxA; PFHpA; PFOA; PFNA; PFDA; PFUnDA; PFDoA; PFTrDA; PFTeDA (PDF p.2 analytes of interest).
Limitations
Goat and sheep results are excluded from this cell. Source individual-analyte means should not be summed to reconstruct lower-bound totals. No total fluorine measurement is supported by the methods. 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.
