Rice finding 1461
Source evidence and comparison details for the Rice profile.
Rice grain unspecified · Lead (Pb) · 11 pooled samples (each 4-6 individual samples).
Selected finding and reference
11 pooled samples (each 4-6 individual samples). Basis: wet weight (as reported; samples dried before analysis and back-calculated).
all rice pools reported as numbers; no non-detects flagged; source does not state treatment of values below LOD
HMI baseline position
Limited data: Held: unit of LOD unresolvable from the text copy. a mean of 93.5 over 11 pools is arithmetically impossible with a maximum of 1100 and a minimum of 25 (the minimum possible mean would be about (1100+10x25)/11 = 123); either the maximum (possibly 110) or the mean is misprinted. Missing evidence never means low contamination.

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
2007
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Rice, Ismailia markets (11 pools)
Purchase or reporting market; growing origin not identified.
Sampling, analysis and reporting limits
Oven drying 60-70 C, dry ashing at 500 C, HNO3 dissolution, graphite-furnace AAS with deuterium background correction (Pd/Mg modifier for Cd, Pb).

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.

No moisture, cooking-yield or species conversion is applied to the original finding above. Any basis conversion used for its HMI comparison is stated separately with the numerical target.
