Why this category can concentrate contaminants
This category is included because contaminant patterns can emerge from soil uptake, concentration during drying or processing, or supply-chain blending.
Metals to watch
Lead, arsenic, cadmium, mercury, nickel, chromium, tin, and aluminum may appear in different proportions depending on source and process profile.
Testing notes
| Testing decision | Why it matters |
|---|---|
| Sampling plan | Lot heterogeneity can mask localized hotspots. |
| Method + LOQ alignment | Limits are meaningful only if methods can quantify near the decision point. |
Stakeholder guidance
Consumers
Use variety and trusted data sources; avoid interpreting a single report without context.
Brands
Map suppliers and request method-aligned certificates, with periodic third-party verification.
Manufacturers
Identify process-control points where concentration or contamination entry is most likely.
