Rice finding 1250
Source evidence and comparison details for the Rice profile.
Brown rice · Total chromium (Cr) · 184 genotypes (3 replicate 1 m2 plots each; 10 grains per plot ground).
Selected finding and reference
184 genotypes (3 replicate 1 m2 plots each; 10 grains per plot ground). Basis: air-dried grain (ground).
all results below the (unstated) quantification limit; excluded from analysis by the authors; no values reported
HMI baseline position
Limited data: The source reports a non-detect without a numerical limit; its position cannot be identified. Missing evidence never means low contamination.
The source reports a non-detect without a numerical limit; its position cannot be identified.
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
2019
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Vietnamese rice collection
Rice variety or type within one study.
Sampling, analysis and reporting limits
HNO3 (In internal standard) + H2O2 block digestion at 115 C; ICP-MS PerkinElmer NexION 2000, He collision mode, University of Nottingham ionomics platform; external calibration.
all results below the (unstated) quantification limit; excluded from analysis by the authors; no values reported
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 |
|---|---|---|
| below_LOD | Li, B, Na, Ti, Cr, Se and Pb concentrations were below the quantification limits. These latter elements were consequently excluded from further analysis. | none |

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.
