Rice finding 1306
Source evidence and comparison details for the Rice profile.
Rice grain · Lead (Pb) · 9 composite samples.
Selected finding and reference
Basis: Washed, dried grain. Cr, Cd and Ni detected below LOQ; Pb not detected. Numerical reporting limits are not established for these entries.
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
Collection period not reported
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Ethiopia · Fogera, Metema and Pawe
Farmland composites.
Sampling, analysis and reporting limits
Flame AAS; recovery 87–113%.
Cr, Cd and Ni detected below LOQ; Pb not detected. Numerical reporting limits are not established for these entries.
Method-limited findings cannot establish zero contamination or a numeric upper bound without the relevant reporting limit.
Shared samples and study overlap
Three regions × three area composites; each combines grain from three farmers (27 farmer contributions, not 27 independent composites).
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.
