Rice finding 2271
Source evidence and comparison details for the Rice profile.
Brown rice (husked), field-collected late-season rice, sun-dried · Inorganic arsenic (iAs) · 208 cultivars (4 plants pooled per cultivar from one paddy).
Selected finding and reference
208 cultivars (4 plants pooled per cultivar from one paddy). Basis: sun-dried brown rice powder; moisture basis not stated (effectively air-dried/dry weight).
No non-detects for tAs/iAs/DMA (detection rate 100%); LOD not 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
2020
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Total (208 cultivars)
All samples in the study.
Sampling, analysis and reporting limits
HNO3/H2O2 digestion, ICP-MS (Agilent 7700x) for Cd and tAs; As species by 1% HNO3 extraction and HPLC-ICP-MS (PRP-X100 anion exchange).
No non-detects for tAs/iAs/DMA (detection rate 100%); LOD not 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.
