Rice finding 819
Source evidence and comparison details for the Rice profile.
Polished white rice (uncooked, as purchased) · Cadmium (Cd) · Sample count unreported.
Selected finding and reference
Sample count unreported. Basis: dry weight.
All values quantified as reported; source does not state LOD/LOQ or non-detect handling.
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
Collection date unreported
No year-by-year sample register is reconstructed from this summary.
Geographic scope
White rice from California and
Reported growing area.
Sampling, analysis and reporting limits
~0.1 g powdered sample, HNO3/HCl/H2O2 hotplate wet digestion (modified Akinyele and Shokunbi), Agilent 7900 ICP-MS; total As only (no speciation).
All values quantified as reported; source does not state LOD/LOQ or non-detect handling.
Source inconsistency noted (does not affect this value): same paragraph gives Texas maximum as 70 µg/kg while Results 3.1 and Table 1 give 71 µg/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.
Reported values, conversion and source locator
| Source statistic | Original result | Displayed unit conversion |
|---|---|---|
| range | white rice from California and Louisiana had Cd concentrations ranging from 1.7 to 14 µg/kg | none (µg/kg) |

No moisture, cooking-yield or species conversion is applied to the original finding above. Any basis conversion used for its HMI comparison is stated separately with the numerical target.
