Rice finding 411
Source evidence and comparison details for the Rice profile.
Polished white rice (from rough rice dried to 11% moisture, dehusked, polished) · Total arsenic (tAs) · Sample count unreported.
Selected finding and reference
Sample count unreported. Basis: unspecified (grain dried to 11% moisture before dehusking; no dry-weight correction stated).
values below detection limit replaced by half the detection limit by the source (Methods 2.2); summary statistics include those substitutions
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.
Collection period
2018–2024
No year-by-year sample register is reconstructed from this summary.
Geographic scope
all water managements
All samples in the study.
Sampling, analysis and reporting limits
Total As and Cd by microwave digestion ICP-MS/MS (Thermo iCap TQ); As species by 2% HNO3 extraction and IC-ICP-MS/MS.
values below detection limit replaced by half the detection limit by the source (Methods 2.2); summary statistics include those substitutions
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.
