Rice finding 829
Source evidence and comparison details for the Rice profile.
Rice grain from rice mills (milling form not stated) · Cadmium (Cd) · 144 rice samples (~100 g each).
Selected finding and reference
144 rice samples (~100 g each). Basis: dry weight per Table 1 caption; Results text states the DL as 0.01 mg/kg wet weight.
All samples below DL 0.01 mg/kg; authors substituted DL/sqrt(2)=0.0071 mg/kg for statistics and risk; not imputed here
HMI baseline position
Limited data: Held: abstract reports the Cd mean as '<0.0001' mg/kg, inconsistent with the stated DL of 0.01 mg/kg and the DL/sqrt(2) substitution (0.0071 mg/kg); the DL basis is given as dry weight (Table 1 caption) and wet weight (Results text). Missing evidence never means low contamination.
Held: abstract reports the Cd mean as '<0.0001' mg/kg, inconsistent with the stated DL of 0.01 mg/kg and the DL/sqrt(2) substitution (0.0071 mg/kg); the DL basis is given as dry weight (Table 1 caption) and wet weight (Results text).
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.

Sampling, analysis and reporting limits
Grain washed with deionized water, oven-dried 80 °C 1 h; HNO3/H2O2 open digestion at 120 °C; Metrohm 797 VA Computrace polarographic (voltammetric) trace analyzer.
All samples below DL 0.01 mg/kg; authors substituted DL/sqrt(2)=0.0071 mg/kg for statistics and risk; not imputed here
Held: abstract reports the Cd mean as '<0.0001' mg/kg, inconsistent with the stated DL of 0.01 mg/kg and the DL/sqrt(2) substitution (0.0071 mg/kg); the DL basis is given as dry weight (Table 1 caption) and wet weight (Results text).
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.
