Rice finding 2416
Source evidence and comparison details for the Rice profile.
Brown rice, long (U.S. market rice) · Inorganic arsenic (iAs) · 1 rice samples (market products).
Selected finding and reference
1 rice samples (market products). Basis: unspecified.
iAs is not printed by the source as a single value; this sample value is As(III)+As(V) from Table 1 (the paper defines inorganic As as III+V). Where As(V) is '<0.005', value_ug_kg is the As(III) lower bound and bound_ug_kg is As(III)+5 µg/kg; no zero imputed.
HMI baseline position
Limited data: Held: Table 1 prints As(V) values of 0.003-0.023 mg/kg and '<0.005', although the stated mean As(V) detection limit is 0.025 mg/kg (Results, Arsenic Species Recovery); As(V) values below 0.025 are therefore below the stated LOD. Computed sum As(III)+As(V); As(III) LOD 0.007, As(V) LOD 0.025 mg/kg. 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
Collection date unreported
No year-by-year sample register is reconstructed from this summary.

Sampling, analysis and reporting limits
Total As: HNO3/H2O2 digestion + ICP-AES (ref 5). Species: 2.0 M TFA extraction at 75 °C, 6 h; IC (AS16) - ICP-DRC-MS (75As16O at m/z 91).
iAs is not printed by the source as a single value; this sample value is As(III)+As(V) from Table 1 (the paper defines inorganic As as III+V). Where As(V) is '<0.005', value_ug_kg is the As(III) lower bound and bound_ug_kg is As(III)+5 µg/kg; no zero imputed.
Held: Table 1 prints As(V) values of 0.003-0.023 mg/kg and '<0.005', although the stated mean As(V) detection limit is 0.025 mg/kg (Results, Arsenic Species Recovery); As(V) values below 0.025 are therefore below the stated LOD. Computed sum As(III)+As(V); As(III) LOD 0.007, As(V) LOD 0.025 mg/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.

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.
