Summary
Commercial and home-produced eggs were analyzed in Croatia. Selected main-analyte table values are held separately by production system.
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.

Methods (brief)
Modified QuEChERS extraction and UHPLC-MS/MS, negative ESI with dynamic multiple reaction monitoring (PDF pp.4 to 7, sections 2.3 to 2.4).
Targets as printed or genericized: PFBA; PFPeA; PFHxA; PFHpA; PFOA; PFNA; PFDA; PFUnDA; PFDoDA; PFTrDA; PFTeDA; PFBS; PFPeS; PFHxS; PFHpS; PFOS isomers; PFNS; PFDS; PFUnDS; PFDoDS; PFTrDS; FOSA; DONA; HFPO-DA; 4:2 FTS; 6:2 FTS; 8:2 FTS; 9Cl-PF3ONS; 11Cl-PF3OUdS; additional sulfonamide standards with commercial identifiers omitted (PDF pp.4,6 to 7).
Limitations
LB and UB statistics must not be collapsed. Table and narrative PFOS descriptions differ; MISMATCHES.csv preserves the conflict. PFBA and PFPeA did not meet the confirmation criterion (PDF p.9). 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.
