Rice finding 1356
Source evidence and comparison details for the Rice profile.
Rice grain unspecified (raw rice from open markets) · Lead (Pb) · Sample count unreported.
Selected finding and reference
Sample count unreported. Basis: unspecified (samples stored dry at room temperature and ground; basis not stated).
minimum reported as '< LD' (below limit of detection; LD value not reported); not imputed
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
2020
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Niankologo
Purchase or reporting market; growing origin not identified.
Sampling, analysis and reporting limits
HNO3/HCl (3:1) digestion of 0.5 g at 150 °C for 2.5 h on a heat block, diluted to 100 mL; flame AAS (Varian 240FS), external calibration.
minimum reported as '< LD' (below limit of detection; LD value not reported); not imputed
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.
