Subchronic [RfC] Comments: |
1E-1 mg/kg/day (see Appendix A-II, Dose Conversions on HEAST). |
Chronic [RfC] Comments: |
1E-2 mg/kg/day (see Appendix A-II, Dose Conversions on HEAST). |
General Comments: |
The subchronic and chronic inhalation [RfC] values were derived from methodology that is not current with the interim inhalation methodology used by the RfD/RfC work group. |
