Rice finding 2275
Source evidence and comparison details for the Rice profile.
Rice grain, 'wild rice' described as a mixture of white and brown rice (Oryza, not Zizania per the authors' description) · Inorganic arsenic (iAs) · 1 commercial rice samples (single packages, replicate determinations).
Selected finding and reference
1 commercial rice samples (single packages, replicate determinations). Basis: unspecified (as-purchased ground rice; no drying step described).
none (quantified)
HMI baseline position
Limited data: Held: iAs (93±17) exceeds total As (92±11) and the iAs percentage is printed as 101±15%; within SD but physically iAs cannot exceed tAs. Missing evidence never means low contamination.
Held: iAs (93±17) exceeds total As (92±11) and the iAs percentage is printed as 101±15%; within SD but physically iAs cannot exceed tAs.
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.
Geographic scope
Wild rice
Rice variety or type within one study.
Sampling, analysis and reporting limits
Total As: microwave HNO3/H2O2 digestion, ICP-MS (NexION 300X). As species: ultrasound-assisted extraction (1:1 methanol/water), ionic-imprinted-polymer vortex-assisted dispersive micro-SPE pre-concentration (factor 10), HPLC-ICP-MS (PRP-X100), standard-addition quantification.
none (quantified)
Held: iAs (93±17) exceeds total As (92±11) and the iAs percentage is printed as 101±15%; within SD but physically iAs cannot exceed tAs.
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.
