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.
4 further transcribed values remain under review and are not shown.
Evidence Fitness
primary_measurement. TF includes inorganic fluorine and cannot be labeled total organic fluorine. Hydrolysis, stored extracts and original extraction are separate measurements. Abstract versus results compound-count discrepancy is logged.
Methods (brief)
PIGE total fluorine; targeted GC-MS and LC-MS/MS; hydrolysis and nontarget analysis (PDF pp.2-4). Full target list and limits referenced to unstaged supporting information.
Analytes or measurement scopes: TF, 6:2 FTOH, 6:2 FTMAc, PFAS precursors. Target identities are not inferred from the manifest acronym scan.
Limitations
Table 1 popcorn paper bag 8 is <LOQ for PIGE (PDF p.3). Abstract reports total F categories <3580, 3580-10800, >10800 µg F/m² (PDF p.1); these are not analyte-specific 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.
