Rice finding 2059

Source evidence and comparison details for the Rice profile.

Navaretnam et al. 2025

White and brown rice, retail · Inorganic arsenic (iAs) · 30 retail rice samples (brands/origins).

Selected finding and reference

96–352 µg/kg (range)Range.

30 retail rice samples (brands/origins). Basis: dry weight (ground rice dried at 60 °C to constant weight before extraction).

No non-detects reported for AsIII, AsV or iAs; LOD AsIII 0.137, AsV 0.142 µg/kg

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.

The source reports a range, percentile or extreme value; only a mean, median or sample result can be positioned against a reference.

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.

Geographic scope

All rice samples

All samples in the study.

Sampling, analysis and reporting limits

0.2% HNO3 heat extraction (90 °C, 90 min, 1 g/10 mL), HPLC (C18 ion-pair, isocratic) with ICP-MS DRC (AsO+ m/z 91); iAs = AsIII + AsV.

No non-detects reported for AsIII, AsV or iAs; LOD AsIII 0.137, AsV 0.142 µg/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.
