Acute RELs

Acute REL (μg/m3): 
2.5
Species: 
Human
Acute REL Toxicologic Endpoint: 
Respiratory and eye irritation
Acute REL Target Organs: 
Respiratory system, eyes
Severity: 
Mild
Last Acute REL Revision: 
2008
Acute Reference Exposure Levels Comments: 

Sensory irritancy is the critical response to acute acrolein exposure. For this effect both the Darley and Weber-Tschopp studies found similar effect levels resulting in similar estimates for the acute REL. In consideration of this, we took the geometric mean of the REL values from these studies to derive the acute REL of 2.5 _g/m3 (1.1 ppb).
