Rice finding 1763
Source evidence and comparison details for the Rice profile.
Packed retail rice grain (form not stated) · Nickel (Ni) · 6 packed cereal samples across 7 commodities (3-11 brands per commodity x 3 samples per brand, each analysed in triplicate); rice n not stated.
Selected finding and reference
6 packed cereal samples across 7 commodities (3-11 brands per commodity x 3 samples per brand, each analysed in triplicate); rice n not stated. Basis: dry weight.
Not detected; LOD reported only as 0.1-0.35 ug/kg range for different metal ions, not per analyte.
HMI baseline position
Limited data: The source reports a non-detect without a numerical limit; its position cannot be identified. Missing evidence never means low contamination.
The source reports a non-detect without a numerical limit; its position cannot be identified.
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
2014
No year-by-year sample register is reconstructed from this summary.
Geographic scope
all rice brands
All samples in the study.
Sampling, analysis and reporting limits
Dry ashing at 500 C, HNO3/H2O2 dissolution, ICP-OES (PerkinElmer 7300 DV).
Not detected; LOD reported only as 0.1-0.35 ug/kg range for different metal ions, not per analyte.
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.
