Findings
The authors could not extrapolate a human-health-based threshold from the reviewed evidence. They distinguished a monitoring screening approach from a demonstrated safe exposure level.
Methods and scope
PDF pp. 1–2 abstract; tiered critical review of mammalian hazard studies and monitoring framework.
What this source can support
Methodological and policy context, not an occurrence survey.
A conservative screening level used to inform monitoring is not an established human-health threshold. No framework-derived number is presented as an observed product concentration.
