Rice finding 1333
Source evidence and comparison details for the Rice profile.
Brown rice · Lead (Pb) · 4 retail rice samples (each analysed in triplicate).
Selected finding and reference
4 retail rice samples (each analysed in triplicate). Basis: unspecified (as-sold grain; no dry-weight correction stated).
<0.064 mg/kg (LOQ), above LOD implied
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.

Rice variety or type within one study.
Sampling, analysis and reporting limits
Microwave-assisted HNO3/H2O2 digestion; ICP-MS (PerkinElmer Elan DRC II); As corrected for 40Ar35Cl+; Pb mean of 206/207/208 isotopes.
<0.064 mg/kg (LOQ), above LOD implied
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.
