Summary
Nationwide Korean drinking-water monitoring. Annual measured means are separated from potency-weighted calculations and risk models. Units remain micrograms per litre as printed.
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 | 0.0032 | µg/L | annual average drinking-water concentration, 2018 | PDF p10, section 3.1 | Numeric analyte-specific limits are not transcribed; retain the cited PDF or unstaged supplement as the limit source. Do not infer a limit. |
| PFOA | 0.0014 | µg/L | annual average drinking-water concentration, 2024 | PDF p10, section 3.1 | Numeric analyte-specific limits are not transcribed; retain the cited PDF or unstaged supplement as the limit source. Do not infer a limit. |
| PFOS | 0.0008 | µg/L | annual average drinking-water concentration, 2018 | PDF p10, section 3.1 | Numeric analyte-specific limits are not transcribed; retain the cited PDF or unstaged supplement as the limit source. Do not infer a limit. |
| PFOS | 0.0003 | µg/L | annual average drinking-water concentration, 2024 | PDF p10, section 3.1 | Numeric analyte-specific limits are not transcribed; retain the cited PDF or unstaged supplement as the limit source. Do not infer a limit. |
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)
SPE-UPLC-MS/MS, PDF pp5-6; target panel and validation in Methods and supporting tables.
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
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_Kim_nationwide-monitoring-and-hepatic-mixture-risk.pdf. SHA-256: 2c600389fc1022a1b7a68bd60e76ea0d93b0de0c3f19d34d88f4fcc25f446be4. 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.
