Estimate of Chronic Reference Dose for Oral Exposure (RfD)Last Updated: 07/30/2008
Please see IRIS.


Estimate of Subchronic Reference Dose for Oral Exposure (RfD)Last Updated: 07/30/2008
System RfD (mg/kg-day) Basis PoD UF Confidence
Whole Body Effects 4 x 10-4 Reduced lifespan and serum chemistry changes. LOAEL : 0.35 mg/kg-day 1000 Low
Species Studied: Rat
Duration: 2 years
Principal Study: Schroeder et al. 1970
Note: The chronic RfD was adopted as the subchronic RfD.

Estimate of Subchronic Reference Concentration for Inhalation Exposure (RfC)Last Updated: 07/30/2008
Data are inadequate to derive a subchronic RfC.
