Rice finding 445
Source evidence and comparison details for the Rice profile.
Rajkowska-Myśliwiec et al. 2024
Brown rice · Total arsenic (tAs) · 30 retail product packages (5 per manufacturer, 6 manufacturers per product group); 60 rice grain packages in scope.
Selected finding and reference
30 retail product packages (5 per manufacturer, 6 manufacturers per product group); 60 rice grain packages in scope. Basis: unspecified (retail product as purchased, homogenised; no dry/fresh basis stated).
All results above the LOD (minimum values 69.5 and 87.6 µg/kg vs LOD 0.3 µg/kg); no non-detects reported.
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.

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
2023
No year-by-year sample register is reconstructed from this summary.
Geographic scope
brown rice
Rice variety or type within one study.
Sampling, analysis and reporting limits
Microwave digestion (HNO3, CEM MDS-2000) then hydride generation ICP-AES/OES (Jobin Yvon JY-24) for total arsenic.
All results above the LOD (minimum values 69.5 and 87.6 µg/kg vs LOD 0.3 µg/kg); no non-detects reported.
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.
