The inherited copper LC50 now has a source, not a safe-level claim
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 screening trail now identifies the 2014 acute copper-ion and chlorpyrifos paper that supplied the 96-hour LC50 values reused by the 2015 biomarker study.
Why it changed
The public eight-page PDF confirms the source relationship and broad acute design, but its current text extraction drops the decisive numerical table cells and rendered-page access could not be completed. The source stays full text needed, and its values are not promoted into the evidence registry or aquarium guidance.

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.
