Summary
Method validation includes a small real-sample application. Only the reported egg PFOA detection is entered as an occurrence row.
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.
No values from this source are published. It is filed as method or context evidence.
1 further transcribed values remain under review and are not shown.
Evidence Fitness
Methods (brief)
Alkaline extraction, solid-phase clean-up and UHPLC-MS/MS selected reaction monitoring (PDF pp.4 to 5).
Targets as printed or genericized: PFPeA; PFHxA; PFHpA; PFOA; PFNA; PFDA; PFUnDA; PFBS; PFHxS; PFHpS; PFOS; PFDS; HFPO-DA (PDF pp.5,10).
Limitations
Application is a small hotspot study, not population prevalence. Validation and occurrence results remain separate. 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.
