Rice finding 1165
Source evidence and comparison details for the Rice profile.
Rice grain as sold, dry products (all HBBF rice containers except the 4 ready-to-heat samples, as reproduced) · Cadmium (Cd) · 141 rice containers (retail products).
Selected finding and reference
141 rice containers (retail products). Basis: dry weight.
Cd detected in all but one rice sample (p.6, p.12); treatment of the one ND (HBR-057, <1.3) in the mean is not stated.
HMI baseline position
Limited data: No compatible reference units exist for this analyte, material and basis after the complete rice ledger. Missing evidence never means low contamination.
No compatible reference units exist for this analyte, material and basis after the complete rice ledger.
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
2024–2025
No year-by-year sample register is reconstructed from this summary.
Geographic scope
all rice samples
All samples in the study.
Sampling, analysis and reporting limits
Total recoverable As, Cd, Pb, Hg by microwave digestion (H2O2/HNO3, AOAC 2015.01 mod.) and ICP-QQQ-MS; As speciation (iAs = As(III)+As(V), MMA, DMA) on rice by dilute-acid digestion and IC-ICP-CRC-MS; Brooks Applied Labs.
Cd detected in all but one rice sample (p.6, p.12); treatment of the one ND (HBR-057, <1.3) in the mean is not stated.
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 |
|---|---|---|
| mean | Average cadmium levels were 18.8 ppb in rice | none (reported in ppb = ug/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.
