Summary
Fortified tap-water interlaboratory method validation. Fortification results are not environmental occurrence measurements. Filed for method context without 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: 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)
SPE-LC/MS/MS validation; target identities Table 1, transitions Table 3; PDF pp2-9.
Detection limits and censoring: LOQ 1 ng/L is a method-development target and blank comparison, PDF pp4 and 9. No fortified recovery is presented as ambient water concentration.
Limitations
- MANIFEST_MEASUREMENT_FITNESS: MANIFEST tier PRIMARY. Comparison: Fortified tap-water method validation across laboratories. Locator: PDF pp1 and 4-9. File method context only; no fortified result treated as ambient occurrence.
