Summary
Residential tap-water monitoring in Besancon. Targeted PFAS and aggregate fluorine measures are separate. The paper discusses limitations of aggregate fluorine methods and does not establish a universal PFAS total.
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.
5 further transcribed values remain under review and are not shown.
Evidence Fitness
Source classification: primary_measurement. MANIFEST tier: PRIMARY. This is a selected, bounded transcription, not an exhaustive extraction of every result in the paper. Each selected number has its own PDF page or table locator. Values for different matrices, isomers, statistics and aggregate assays are not interchangeable.
Methods (brief)
Anion-exchange SPE and LC-ESI-MS/MS for targeted PFAS, PDF p4. Aggregate AOF is described separately in PDF p5 and has an internally inconsistent method description. Target list/limits referred to unstaged Table S1.
Detection limits and censoring: Numeric analyte-specific limits are not transcribed; retain the cited PDF or unstaged supplement as the limit source. Do not infer a limit.
Limitations
- ABSTRACT_BODY_DENOMINATOR: Abstract 41 samples with mixtures. Comparison: Body 40 positive-mixture samples. Locator: PDF p1 abstract versus p6 Results. All subset means HOLD; preserve counts as printed in log.
- BODY_ANALYTE_COUNT: Body alternately says 12 molecules and 11 substances. Comparison: Listed compounds and TFA discussion have inconsistent counting. Locator: PDF p6 Results. No inferred complete-panel detection count; selected concentrations only.
- AGGREGATE_METHOD_DESCRIPTION: AOF description refers to adsorption coupled with liquid chromatography. Comparison: QA discussion refers to combustion efficiency and ion chromatography. Locator: PDF p5. Do not equate AOF to targeted PFAS or emit aggregate concentration data.
Provenance notes
Citation metadata verified against PDF p1, title, author byline, journal citation or masthead, and DOI.. Article DOI appears in the supplied PDF and matches the MANIFEST case-insensitively. Original file: 2026_Crini_identification-and-quantification-of-pfas-in.pdf. SHA-256: 732ed4762b990f10cad1a0fac3bce42ecb68db8a795b0cc0a832ef5325d8c71e. Original MANIFEST remains in the copied packet; discrepancies are listed without modifying it. Commercial analyte synonyms, instrument brands and manufacturer names are generalized in authored index prose.
