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.
