Summary
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.
2 further transcribed values remain under review and are not shown.
Evidence Fitness
primary_measurement. Detection frequency is not a concentration. TF is not specific to organic fluorine or PFAS. Thick paperboard examined on both sides; higher surface signal selected (PDF p.3).
Methods (brief)
PIGE total fluorine screening; LC/TOF MS subset with targeted and suspect screening (PDF pp.2-3).
Analytes or measurement scopes: TF, PFOA, PFHxA, PFBS, 6:2 FTS. Target identities are not inferred from the manifest acronym scan.
Limitations
PIGE LOD 16 nmol F/cm²; LOQ 50 nmol F/cm² (PDF p.3). Between-LOD-and-LOQ values are estimated.
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.
