Rice finding 1521
Source evidence and comparison details for the Rice profile.
Rice grain, raw, as sold (packaged 'Rice "Oryza Sativa"') · Lead (Pb) · 1 retail food items (one sample each, Pb determined in duplicate); 103 items overall.
Selected finding and reference
1 retail food items (one sample each, Pb determined in duplicate); 103 items overall. Basis: dry weight (solid items dehydrated at 80 °C for 72 h before grinding and digestion; table does not label basis explicitly).
Values at or below LoQ printed as '<LoQ'; LoQ 0.0025 mg/kg; values >LoQ considered detected; no imputation
Low / Moderate / High rating
No relative rating: reporting limits leave the target median bounded. Overlapping bounds do not establish equal levels or a direction of difference.
Selected comparison
Limits overlapNo compatible same-study subgroup with the same statistic, basis and analyte.Within-study comparisons use the same source, analyte, statistic and analytical method.Collection period
2022–2023
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Rice "Oryza Sativa" (Brand 3)
Purchase or reporting market; growing origin not identified.
Sampling, analysis and reporting limits
HNO3 digestion (water bath 60 °C), graphite furnace AAS (PerkinElmer AAnalyst-600, HGA-600).
Values at or below LoQ printed as '<LoQ'; LoQ 0.0025 mg/kg; values >LoQ considered detected; no imputation
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.
