Rice finding 2169
Source evidence and comparison details for the Rice profile.
Brown nonaromatic rice (U.S.) · Inorganic arsenic (iAs) · 120 rice packages (samples); CR2014 128 rice packages from 49 models, plus 66+31 CR2012 and 473 FDA samples.
Selected finding and reference
120 rice packages (samples); CR2014 128 rice packages from 49 models, plus 66+31 CR2012 and 473 FDA samples. Basis: as sold (uncooked); dry/fresh basis not stated.
Report does not state LOD/LOQ or how non-detects were handled; no non-detects are printed.
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
2012–2014
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Nonaromatic brown rice
Reported growing area.
Sampling, analysis and reporting limits
Total As: HNO3/H2O2 digestion (EPA 3050B), ICP-DRC-MS (EPA 200.8). Species (arsenite, arsenate, MMA, DMA): TFA extraction, IC-ICP-CRC-MS per FDA EAM 4.11. 'Total inorganic arsenic' = arsenite + arsenate..
Report does not state LOD/LOQ or how non-detects were handled; no non-detects are printed.
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.
Reported values, conversion and source locator
| Source statistic | Original result | Displayed unit conversion |
|---|---|---|
| range | nonaromatic-type brown rice (from all regions of the U.S.), which had average total inorganic arsenic levels that ranged from 136.7 ppb (6.2 mcg per serving) to 180.6 ppb (8.1 mcg per serving) and went as high as 249.0 ppb (11.2 mcg per serving). | ppb = µg/kg (none) |
