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.
3 further transcribed values remain under review and are not shown.
Evidence Fitness
primary_measurement. Table 1 EOF available for Saudi Arabia and UK only. Abstract mass/area unit pairing is not used for conversion. Several unit and abstract/table inconsistencies remain held.
Methods (brief)
EOF by high-resolution graphite furnace molecular absorption spectrometry; targeted LC-MS/MS and nontarget LC-ICP-MS/MS-ESI-HRMS (PDF pp.3-5). Target PFAS list is referenced to unstaged supplement.
Analytes or measurement scopes: EOF, PFCA, PFSA, PFOSA, PFOPA. Target identities are not inferred from the manifest acronym scan.
Limitations
LOD/LOQ calculation described on PDF p.4, with target limits in µg F L⁻¹; numerical per-analyte limits not transcribed without supplement. Table 1 missing EOF remains a dash, not ND.
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.
