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 |
|---|---|---|---|---|---|
| 6:2 FTOH | 14.6 | ng/g Material | Cumulative gas yield from Popcorn Bags 1 landfill reactor; not food migration | PDF p.5, Table 2 | Paper sets peaks below LOD to zero and uses estimated concentrations between LOD and LOQ in gas yields (PDF p.4). Selected table values retain the original reported result; no new substitution. Numerical analyte limits reside in unstaged supporting information. |
| 6:2 FTOH | 99.7 | ng/g Material | Cumulative gas yield from Popcorn Bags 2 landfill reactor; not food migration | PDF p.5, Table 2 | Paper sets peaks below LOD to zero and uses estimated concentrations between LOD and LOQ in gas yields (PDF p.4). Selected table values retain the original reported result; no new substitution. Numerical analyte limits reside in unstaged supporting information. |
| 6:2 FTOH | 474 | ng/g Material | Cumulative gas yield from Biodegradable Boxes landfill reactor; not food migration | PDF p.5, Table 2 | Paper sets peaks below LOD to zero and uses estimated concentrations between LOD and LOQ in gas yields (PDF p.4). Selected table values retain the original reported result; no new substitution. Numerical analyte limits reside in unstaged supporting information. |
Evidence Fitness
primary_measurement. Landfill release is not food migration or initial packaging concentration. Terminated Popcorn Bags 1 reactor is distinct from completed reactors (PDF p.5).
Methods (brief)
PIGE screening followed by volatile PFAS gas analysis using thermal desorption GC-MS (PDF pp.2-4). Table 2 lists FTOHs, FTOs, FTIs, FTAcs, FTMAcs and sulfonamide derivatives.
Analytes or measurement scopes: 6:2 FTOH, volatile PFAS. Target identities are not inferred from the manifest acronym scan.
Limitations
Paper sets peaks below LOD to zero and uses estimated concentrations between LOD and LOQ in gas yields (PDF p.4). Selected table values retain the original reported result; no new substitution. Numerical analyte limits reside in unstaged supporting information.
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.
