| 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). Typo in the Acrolein REL documentation – for the Haber’s Law adjustment, Section 5.4.1 (Concentration and Time Extrapolation using Haber’s Law) corrected in this update. |
