Rice finding 1344
Source evidence and comparison details for the Rice profile.
Polished rice · Lead (Pb) · 2 retail rice samples (each analysed in triplicate).
Selected finding and reference
2 retail rice samples (each analysed in triplicate). Basis: unspecified (as-sold grain; no dry-weight correction stated).
As reported by the source
HMI baseline position
Limited data: The source reports a range, percentile or extreme value; only a mean, median or sample result can be positioned against a reference. Missing evidence never means low contamination.
The source reports a range, percentile or extreme value; only a mean, median or sample result can be positioned against a reference.
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.
Collection period
2013–2015
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Polished (samples above LOQ)
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.
