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 | 0.52-0.70 | µg/kg | Migration into food simulants under intended use conditions | PDF p.7, section 2.3.2 | Residue PFOA LOD 0.2 and LOQ 0.5 µg/L; PFOS LOD 0.5 and LOQ 1.2 µg/L (Table 3, PDF p.4). Migration Figure 3 states PFOA/PFPeA LOQ ~0.5 µg/kg and PFOS/PFNA/PFHxA ~0.5-3 µg/kg (PDF p.7). |
| PFNA | below their respective LOQs | µg/kg | Migration into all four simulants under standardized conditions | PDF p.7, section 2.3.2 and Figure 3 caption | Residue PFOA LOD 0.2 and LOQ 0.5 µg/L; PFOS LOD 0.5 and LOQ 1.2 µg/L (Table 3, PDF p.4). Migration Figure 3 states PFOA/PFPeA LOQ ~0.5 µg/kg and PFOS/PFNA/PFHxA ~0.5-3 µg/kg (PDF p.7). |
| PFOS | below their respective LOQs | µg/kg | Migration into all four simulants under standardized conditions | PDF p.7, section 2.3.2 and Figure 3 caption | Residue PFOA LOD 0.2 and LOQ 0.5 µg/L; PFOS LOD 0.5 and LOQ 1.2 µg/L (Table 3, PDF p.4). Migration Figure 3 states PFOA/PFPeA LOQ ~0.5 µg/kg and PFOS/PFNA/PFHxA ~0.5-3 µg/kg (PDF p.7). |
| PFHxA | below their respective LOQs | µg/kg | Migration into all four simulants under standardized conditions | PDF p.7, section 2.3.2 and Figure 3 caption | Residue PFOA LOD 0.2 and LOQ 0.5 µg/L; PFOS LOD 0.5 and LOQ 1.2 µg/L (Table 3, PDF p.4). Migration Figure 3 states PFOA/PFPeA LOQ ~0.5 µg/kg and PFOS/PFNA/PFHxA ~0.5-3 µg/kg (PDF p.7). |

Evidence Fitness
primary_measurement. Pulp tableware is adjacent packaging evidence, not a carton-specific estimate. Residue and migration units and limits differ. Safety and regulatory claims are not adopted.
Methods (brief)
LC-MS/MS target list PFOA, PFOS, PFNA, PFHxA, PFPeA (PDF p.4, Table 3). TF and EOF determined with ion-selective electrode (PDF pp.2-3). Conditions vary by container and simulant (Table 6, PDF p.7).
Analytes or measurement scopes: PFOA, PFOS, PFNA, PFHxA, PFPeA, TF, EOF. Target identities are not inferred from the manifest acronym scan.
Limitations
Residue PFOA LOD 0.2 and LOQ 0.5 µg/L; PFOS LOD 0.5 and LOQ 1.2 µg/L (Table 3, PDF p.4). Migration Figure 3 states PFOA/PFPeA LOQ ~0.5 µg/kg and PFOS/PFNA/PFHxA ~0.5-3 µg/kg (PDF p.7).
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.
