Rice finding 1773
Source evidence and comparison details for the Rice profile.
White rice (milled: hull, bran, aleurone and germ removed; air-dried) · Nickel (Ni) · 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); dry basis not otherwise stated.
none reported for this analyte (detected above quantification limit)
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.

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.
none reported for this analyte (detected above quantification limit)
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.
