Rice finding 1876
Source evidence and comparison details for the Rice profile.
Polished (white) rice · Inorganic arsenic (iAs) · 10 rice samples (Table 1 per-zone 'No. of values' sum to 1093).
Selected finding and reference
10 rice samples (Table 1 per-zone 'No. of values' sum to 1093). Basis: dry weight (freeze-dried grain).
Source states LoD 3 ug/kg for iAs and DMA (Methods) and '< 2' in Abstract/Results; Table 1 prints numeric values for low results without flagging non-detects.
HMI baseline position
Limited data: Held: printed value is at or below the method LoD of 3 ug/kg (abstract gives <2); likely an LoD-substituted or below-LoD value, treat as bounded <=3 ug/kg. Missing evidence never means low contamination.
Held: printed value is at or below the method LoD of 3 ug/kg (abstract gives <2); likely an LoD-substituted or below-LoD value, treat as bounded <=3 ug/kg.
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.

Sampling, analysis and reporting limits
Freeze-dried, ball-milled grain; 1% HNO3 microwave extraction (CEM MARS 6, 95 C), H2O2 oxidation of arsenite to arsenate; IC (Thermo IC5000, AS7 column) coupled to ICP-MS (Thermo iCAP Q, m/z 75, He collision mode).
Source states LoD 3 ug/kg for iAs and DMA (Methods) and '< 2' in Abstract/Results; Table 1 prints numeric values for low results without flagging non-detects.
Held: printed value is at or below the method LoD of 3 ug/kg (abstract gives <2); likely an LoD-substituted or below-LoD value, treat as bounded <=3 ug/kg.
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.
