This is a thesis, not a peer-reviewed article. Hard-candy lead means in the thesis depend on how non-detects are entered (substitution at 0, 0.005, or 0.01 μg/g, or a detectable-only rule). The detectable count disagrees between an appendix (18) and Table 9 (19). No recovery percentage is printed. A substituted zero is not a measured concentration, so this note does not publish a hard-candy lead mean from the thesis.
Key numbers
Data gap: no hard-candy lead concentration is copied, because the printed means are tied to a non-detect rule that this page will not treat as a measurement.
Methods (brief)
Imported candies from Clark County, Nevada, were tested for lead and grouped by candy type.
Evidence fitness
The thesis documents that hard candy was in the sample frame. It does not support a numeric hard-candy lead value on this page.
Limitations
Thesis. Non-detect handling is not a measured zero. Counts disagree inside the document.
