Rice finding 865
Source evidence and comparison details for the Rice profile.
Polished rice · Cadmium (Cd) · 27 retail rice samples (each analysed in triplicate).
Selected finding and reference
27 retail rice samples (each analysed in triplicate). Basis: unspecified (as-sold grain; no dry-weight correction stated).
summary reported as <0.040 mg/kg (LOQ)
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.
Selected comparison
Limits overlapPolished (present study): <40 µg/kg; the study total (All samples): <12 µg/kg. Reporting limits overlap, so the direction is unresolved.Within-study comparisons use the same source, analyte, statistic and analytical method.Collection period
2013–2015
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Polished (present study)
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.

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.
