Recovered particles are not a measured health effect
The evidence library is allowed to change in public. This page preserves the revised boundary, why it moved and which guides were affected.
What changed
The chemical-safety guide now includes a 2021 N. palmata ingestion and four-hour egestion experiment while separating particle recovery from harm, safety, tissue transfer, complete clearance and a shape-only effect.
Why it changed
The study used one independent run with seven to eight surviving one-shrimp vessels per treatment. Immediate and four-hour values came from separate animals with very large variability, and the supplement supplies only group summaries. Beads and fragments differed in polymer, size distribution, preparation and detection, while no chronic survival, growth, reproduction, histology or verified home exposure was measured.

Affected practical guides
A public change is not automatically a retraction. A source may be added, a scope narrowed, a gap refined or an error corrected. The current guide and registry record own the current wording.
