Rice finding 1529
Source evidence and comparison details for the Rice profile.
Rice grain unspecified (washed, dried, powdered) · Lead (Pb) · 3 area composites (3 per region), each of 3 x 0.5 kg farmer samples (27 farmer samples).
Selected finding and reference
3 area composites (3 per region), each of 3 x 0.5 kg farmer samples (27 farmer samples). Basis: dry weight.
not detected: below method LOD 4.5 mg/kg (4500 µg/kg); not imputed
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
Hot-plate digestion HNO3:HClO4:H2O2 (4:2:1, 7 mL, 160 °C, 1 h); flame AAS (Buck Scientific 210VGP) with deuterium background correction.
not detected: below method LOD 4.5 mg/kg (4500 µg/kg); not imputed
Source inconsistency noted (does not affect this value): FAAS rice LOD 4.5 mg/kg / LOQ 15.0 mg/kg (4500/15000 µg/kg) is far above typical rice Pb concentrations and above the Codex cereal Pb ML of 0.2 mg/kg, so this non-detect is uninformative about Pb.
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.
