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.
| analyte | value | unit | basis | source location | limits and qualifiers |
|---|---|---|---|---|---|
| PFOA | 4.32 | pg/cm² | FF2; targeted PFAS analysis | PDF p.4, section 3.2.1 | EOF MDL 0.04-0.07 µg/cm² (PDF p.4). Instrument-specific fluorine limits are not interchangeable with individual PFAS limits. |
| PFOA | 22.4 | pg/cm² | MP5; targeted PFAS analysis | PDF p.4, section 3.2.1 | EOF MDL 0.04-0.07 µg/cm² (PDF p.4). Instrument-specific fluorine limits are not interchangeable with individual PFAS limits. |
1 further transcribed values remain under review and are not shown.
Evidence Fitness
primary_measurement. Method comparison includes measured packaging. Surface-sensitive PIGE and bulk methods differ for thick paperboard. The sum of targeted PFAS is not EOF.
Methods (brief)
CIC, PIGE and instrumental neutron activation for TF; CIC EOF and UHPLC-MS/MS target analysis (PDF pp.2-4).
Analytes or measurement scopes: TF, EOF, PFOA, PFHxA, PFAS precursors. Target identities are not inferred from the manifest acronym scan.
Limitations
EOF MDL 0.04-0.07 µg/cm² (PDF p.4). Instrument-specific fluorine limits are not interchangeable with individual PFAS limits.
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.
