Summary
Drinking-water targeted quantification and suspect screening. Instrumental identification confidence is distinct from this ingest scientific HOLD.
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 | 39.8 | ng/L | drinking-water site P6, targeted quantified concentration | PDF p8, section 3.1 Quantitative Study | Below-LOQ identifications are not treated as quantified concentrations; PDF pp8-9 discusses those samples. |
| PFOS | 205.3 | ng/L | drinking-water site P6, targeted quantified concentration | PDF p8, section 3.1 Quantitative Study | Below-LOQ identifications are not treated as quantified concentrations; PDF pp8-9 discusses those samples. |
| PFHxA | 62.6 | ng/L | drinking-water site P6, targeted quantified concentration | PDF p8, section 3.1 Quantitative Study | Below-LOQ identifications are not treated as quantified concentrations; PDF pp8-9 discusses those samples. |
| PFBS | 76.9 | ng/L | drinking-water site P6, targeted quantified concentration | PDF p8, section 3.1 Quantitative Study | Below-LOQ identifications are not treated as quantified concentrations; PDF pp8-9 discusses those samples. |
| PFHxS | 244.3 | ng/L | drinking-water site P6, targeted quantified concentration | PDF p8, section 3.1 Quantitative Study | Below-LOQ identifications are not treated as quantified concentrations; PDF pp8-9 discusses those samples. |
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)
UHPLC high-resolution tandem mass spectrometry with targeted quantification and data-dependent suspect screening, PDF pp4-7. Numeric limits referred to unstaged Table S6.
Detection limits and censoring: Below-LOQ identifications are not treated as quantified concentrations; PDF pp8-9 discusses those samples.
Limitations
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.
