Rice finding 2224
Source evidence and comparison details for the Rice profile.
Parboiled rice · Inorganic arsenic (iAs) · 131 analytical results/samples of rice grain with iAs data (Table 4 sum 1,756 + 7 red rice; text states n = 1,768); 13,608 iAs results overall in food and water.
Selected finding and reference
131 analytical results/samples of rice grain with iAs data (Table 4 sum 1,756 + 7 red rice; text states n = 1,768); 13,608 iAs results overall in food and water. Basis: as reported (not stated).
7% of results left-censored; individual LODs/LOQs not given per rice type (food iAs LOQ cut-off 100 µg/kg; lowest rice LOQs 0.008-4 µg/kg by method)
HMI baseline position
Limited data: The source reports a non-detect without a numerical limit; its position cannot be identified. Missing evidence never means low contamination.
The source reports a non-detect without a numerical limit; its position cannot be identified.
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
2013–2018
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Rice, parboiled
Rice variety or type within one study.
Sampling, analysis and reporting limits
Various laboratory methods reported by data providers; ICP-MS dominant (n=3,521 of food iAs results), also HG-AAS, ICP-HGAES, HPLC-HGAFS, HPLC-ICP-MS.
7% of results left-censored; individual LODs/LOQs not given per rice type (food iAs LOQ cut-off 100 µg/kg; lowest rice LOQs 0.008-4 µg/kg by method)
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.
