Summary
Non-targeted screening of household tap-water extracts. Peak abundance and structural identification confidence do not supply calibrated mass concentrations. Filed with no occurrence concentration 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: suspect_screening. 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)
Modified EPA Method 533 extraction followed by UPLC high-resolution MS/MS and suspect screening, PDF pp2-3. Targeted prior work and the present non-targeted feature set are distinct.
Detection limits and censoring: No concentration LOD is inferred for non-targeted abundance features. This paper and the staged DeLuca study use overlapping household-study material; they are not independent prevalence samples.
Limitations
- OVERLAPPING_COHORT: Same household survey named in staged DeLuca source. Comparison: Different analytical scope; not an independent prevalence sample. Locator: PDF pp2-3 and DeLuca Methods. Cross-reference study overlap; no double-counted study prevalence.
