Rice finding 324
Source evidence and comparison details for the Rice profile.
Rice, uncooked and cooked combined · Total arsenic (tAs) · 814 rice samples (408 uncooked, 406 cooked) from 410 households.
Selected finding and reference
814 rice samples (408 uncooked, 406 cooked) from 410 households. Basis: unspecified.
Censoring not described; no non-detects reported (lowest value 50 ug/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.
Collection period
2016
No year-by-year sample register is reconstructed from this summary.
Geographic scope
rice samples from 410 HEALS
All samples in the study.
Sampling, analysis and reporting limits
Microwave digestion; total As by ICP-MS directly or as the sum of species by HPLC-ICP-MS (FDA EAM 4.11).
Censoring not described; no non-detects reported (lowest value 50 ug/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.
