Rice finding 311
Source evidence and comparison details for the Rice profile.
Rice grains (EFSA concise sub-group 'Rice grains'; form not specified) · Total arsenic (tAs) · 1122 analytical results (samples) for rice grains.
Selected finding and reference
1122 analytical results (samples) for rice grains. Basis: as reported by laboratories (whole/fresh mass implied; LODs expressed as fresh mass, Figure 5); not stated per sample.
9.8% of results <LOD/<LOQ. LB sets censored results to 0, UB to the reported LOD/LOQ (EFSA). Not imputed here.
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
2003–2008
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Rice grains
All samples in the study.
Sampling, analysis and reporting limits
Total arsenic; methods across the whole data set HG-AAS 39%, ET-AAS 12%, ICP-MS 10%, unspecified 39%; not cross-tabulated by matrix.
9.8% of results <LOD/<LOQ. LB sets censored results to 0, UB to the reported LOD/LOQ (EFSA). Not imputed here.
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.
