Rice finding 831
Source evidence and comparison details for the Rice profile.
Rice grain from rice mills (milling form not stated) · Cadmium (Cd) · 48 rice samples (~100 g each).
Selected finding and reference
48 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
Low / Moderate / High rating
No relative rating: reporting limits leave the target median bounded. Overlapping bounds do not establish equal levels or a direction of difference.

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
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.
