Rice finding 824
Source evidence and comparison details for the Rice profile.
Commercial Se-enriched rice (form unstated) · Cadmium (Cd) · 54 retail rice samples (about 1 kg each, different brands).
Selected finding and reference
54 retail rice samples (about 1 kg each, different brands). Basis: dry weight (dried to constant weight before analysis).
minimum reported as < LOD; LOD value in Table S2 (not in text copy); not imputed
HMI baseline position
Limited data: The source reports a range, percentile or extreme value; only a mean, median or sample result can be positioned against a reference. Missing evidence never means low contamination.
The source reports a range, percentile or extreme value; only a mean, median or sample result can be positioned against a reference.
Reference version and interpretation
Frozen evidence selection: 2026-10-22. Method: hmi-pooled-reference-v2.
No admitted reference
The reference is computed by HMI from admitted evidence, not copied from a study baseline. It describes the evidence currently in this scope; it is not a worldwide or current-lot benchmark. Source, year and region filters do not change it. Different HMI scopes are not one common ranking.
Collection period
2023
No year-by-year sample register is reconstructed from this summary.
Geographic scope
all Se-enriched rice samples
All samples in the study.
Sampling, analysis and reporting limits
portable HDXRF spectrometer (XR700, JP Scientific) for total As and Cd; JP500 for total Se; PBET in vitro digestion with AFS for bioaccessible Se.
minimum reported as < LOD; LOD value in Table S2 (not in text copy); not imputed
Shared samples and study overlap
Subgroup rows, statistics of the same subgroup and the study total share samples; they are not independent results.
Each table row describes a food/analyte result. Repeated rows do not add independent samples or datasets. No cross-study trend is calculated in this comparison mode.
Reported values, conversion and source locator

No moisture, cooking-yield or species conversion is applied to the original finding above. Any basis conversion used for its HMI comparison is stated separately with the numerical target.
