Evidence Fitness
primary_measurement. Migration values are not concentrations in prepared popcorn. PFOA-equivalent risk models are not occurrence measurements.
Methods (brief)
UHPLC-Orbitrap HRMS; target compounds and reference standards in Table 5, PDF p.10. Calibration criteria reference EPA 1633, but this is not an EPA 1633 matrix determination. Migration test uses 10% and 50% ethanol at 70 °C for 2 h (PDF p.9).
Analytes or measurement scopes: PFHxA, PFHpA, PFOA, PFNA, PFDA, PFUnA, PFDoA. Target identities are not inferred from the manifest acronym scan.
Limitations
PFOA LOQ 0.2 ng/mL (Table 1, PDF p.3); no conversion to paper mass or surface area. Table 2 dash and blank cells are not zero.
Selected rows are a bounded extraction, not a complete transcription of every table. Supplied main articles are the evidence boundary; unstaged supplements were not retrieved. Aggregate fluorine, targeted PFAS, migration, material content, detection frequency and modeled exposure remain distinct. All findings remain HOLD pending Elon verification.
