Summary
Selected quantifiable and trace yolk results from the egg monitoring study.
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 |
|---|---|---|---|---|---|
| PFOS | 0.4 | ng/g | Homogenized egg yolk; group A pool 1 | PDF p.3 Table 3; limits p.2 | LOD 0.1 ng/g; LOQ 0.25 ng/g. |
| PFHxS | 0.4 | ng/g | Homogenized egg yolk; group A pool 3 | PDF p.3 Table 3; limits p.2 | LOD 0.1 ng/g; LOQ 0.25 ng/g. |
| PFOA | traces | ng/g | Homogenized egg yolk; group A pool 1 | PDF p.3 Table 3; limits p.2 | traces = between LOD and LOQ; LOD 0.1, LOQ 0.25 ng/g. |
| PFHxS | traces | ng/g | Homogenized egg yolk; group A pool 2 | PDF p.3 Table 3; limits p.2 | traces = between LOD and LOQ; LOD 0.1, LOQ 0.25 ng/g. |
| PFNA | traces | ng/g | Homogenized egg yolk; group C pool 2 | PDF p.3 Table 3; limits p.2 | traces = between LOD and LOQ; LOD 0.1, LOQ 0.25 ng/g. |
Evidence Fitness
Methods (brief)
Alkaline digestion, methanol extraction, weak anion exchange SPE and UPLC-MS/MS (PDF p.2).
Targets as printed or genericized: PFNA; PFOA; PFHxS; PFOS (PDF p.2).
Limitations
Source uses dash marks elsewhere; they are not recoded as zero. Selected trace records do not enumerate every trace occurrence. 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.
