Summary
Although the title and MANIFEST refer to drinking water, the actual application is source water: the Chinese text explicitly states water-source samples in section 2.4 (PDF p7). Filed as supportive method/source-water context with no finished tap-water occurrence rows.
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.
Evidence Fitness
Source classification: source_water_method_validation. 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)
Automated SPE-UPLC-MS/MS, PDF pp3-5, Table 1 for target transitions.
Detection limits and censoring: PFOA LOD 0.2 ng/L and LOQ 0.60 ng/L, PDF p6 Table 2. The sample table uses a dash for unreported/not-detected entries; retain its definition rather than zero.
Limitations
- MANIFEST_MATRIX_SCOPE: MANIFEST and title describe drinking-water method. Comparison: Actual water application uses source water in Chinese section 2.4. Locator: PDF pp7-8. Method/source-water context only; no finished tap-water occurrence row.
