Rice finding 897
Source evidence and comparison details for the Rice profile.
Rice grain, husk removed by mortar and pestle (dehusked/brown grain), IRRI variety unspecified · Cadmium (Cd) · Sample count unreported.
Selected finding and reference
Sample count unreported. Basis: unspecified (dry-weight basis stated only for soil).
no non-detects reported for grain metals
HMI baseline position
Limited data: Held: Table 6 Cd HQ for Field-II (0.748) equals Field-I and is inconsistent with Table 5 ADD 1.84e-4 / RfD 5e-4 = 0.37; Table 3 value is consistent with Table 5. Mean of repeat measurements per field (statistic inferred from 'calculating the ADD using mean concentrations'); number of plants/grain subsamples per field not reported. Contaminated/industrial-area fields; total element (no speciation). 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.

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.
