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.
Evidence Fitness
perspective_context. Perspective rather than primary concentration study; no secondary measurement duplication.
Methods (brief)
Perspective on fabrication techniques, barrier performance and legal context (PDF p.1).
Analytes or measurement scopes: fluorinated compounds. Target identities are not inferred from the manifest acronym scan.
Limitations
Not a new PFAS occurrence assay; no method limit is applied to product rows.
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.
