Rice finding 1427
Source evidence and comparison details for the Rice profile.
Packaged rice grain as consumed in households (milling state not stated; raw, uncooked) · Lead (Pb) · 3 analyses (30 brand composites x triplicate) from 250 household rice packs.
Selected finding and reference
3 analyses (30 brand composites x triplicate) from 250 household rice packs. Basis: unspecified (method equation describes concentration as mg/g dry weight; Table 1 basis not stated).
No non-detects reported; instrument detection limits As 0.179, Cd 0.049, Pb 2.166 ppb (solution).
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
Collection date unreported
No year-by-year sample register is reconstructed from this summary.
Geographic scope
brand H-IN
Rice variety or type within one study.
Sampling, analysis and reporting limits
Acid digestion (HNO3/HClO4/H2SO4, ASTM) of 2 g sample; ICP-OES (Spectro Arcos). Abstract says ICP-MS. No arsenic speciation..
No non-detects reported; instrument detection limits As 0.179, Cd 0.049, Pb 2.166 ppb (solution).
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.
