Chickens’ eggs and the livers of farm animals as sources of perfluoroalkyl substances

Quoted values stay tied to the cited study. Empty sections are gaps.

Summary

The paper measures eggs and animal livers. This cell retains egg concentrations only.

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)

Isotope dilution LC-MS/MS; extraction and SPE clean-up (PDF p.2).

Targets as printed or genericized: PFBS; PFHxA; PFHpA; PFHxS; PFOA; PFNA; L-PFOS; Br-PFOS; PFDA; PFPeS; PFHpS; PFUdA; PFDoA (PDF p.3 Table 1).

Limitations

Means in tables are retained literally without reconstructing their denominators. Printed PFOS range is malformed; no decimal is inserted. Wet-weight limits do not change the table unit. 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.
