Rice finding 619
Source evidence and comparison details for the Rice profile.
Uncooked polished white rice (straight from packet) · Cadmium (Cd) · 10 retail rice types (triplicate treatments).
Selected finding and reference
10 retail rice types (triplicate treatments). Basis: dry weight (freeze-dried grain; 'dry weight was calculated separately').
Source substituted half LoD for values below LoD; Cd LoD 0.006 mg/kg equals the reported minimum, so the minimum is at the LoD (may be a censored/substituted value).
HMI baseline position
Limited data: Held: minimum equals Cd LoD (0.006 mg/kg) and below-LoD values were replaced by half-LoD (0.003), so the low end is not a quantified value. Missing evidence never means low contamination.
Held: minimum equals Cd LoD (0.006 mg/kg) and below-LoD values were replaced by half-LoD (0.003), so the low end is not a quantified value.
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
Ten retail polished rice types
Purchase or reporting market; growing origin not identified.
Sampling, analysis and reporting limits
ICP-MS (Thermo iCAP Q) after HNO3/H2O2 microwave digestion for Cd and tAs; IC-ICP-MS (Thermo IC5000 + AS7) for As species; XRF for nutrients.
Source substituted half LoD for values below LoD; Cd LoD 0.006 mg/kg equals the reported minimum, so the minimum is at the LoD (may be a censored/substituted value).
Held: minimum equals Cd LoD (0.006 mg/kg) and below-LoD values were replaced by half-LoD (0.003), so the low end is not a quantified value.
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 | Cadmium in the rice investigated ranged by over an order-of-magnitude, from 0.006 to 0.077 mg/kg (Figure 1) | mg/kg x 1000 |

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.
