Rice finding 1460
Source evidence and comparison details for the Rice profile.
Unpolished white rice · Lead (Pb) · Sample count unreported.
Selected finding and reference
Sample count unreported. Basis: unspecified.
all samples above LOD per authors
HMI baseline position
Limited data: Held: cannot be reproduced from Table 2 (unpolished white Pb rows Suwadel 6.4 and Ran Kahawanu 15 average 10.7). Missing evidence never means low contamination.
Held: cannot be reproduced from Table 2 (unpolished white Pb rows Suwadel 6.4 and Ran Kahawanu 15 average 10.7).
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
Collection date unreported
No year-by-year sample register is reconstructed from this summary.
Geographic scope
unpolished white varieties
Rice variety or type within one study.
Sampling, analysis and reporting limits
10-20 grains ground, HNO3/HCl overnight digest, solution ICP-MS (Agilent 7700s) with Rh internal standard, 8-point calibration 0.6-600 µg/kg; LA-ICP-MS imaging (unquantified).
all samples above LOD per authors
Held: cannot be reproduced from Table 2 (unpolished white Pb rows Suwadel 6.4 and Ran Kahawanu 15 average 10.7).
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
| Source statistic | Original result | Displayed unit conversion |
|---|---|---|
| mean | Unpolished red varietals had higher mean Pb (22 versus 6.8 μg kg−1) and lower Cd (12 versus 42 μg kg−1) concentrations than white rice | none |
