Chronic [RfC] Comments: |
5E-3 mg/kg/day (see Appendix A-II, Dose Conversions on HEAST). Under review, current number subject to change. |
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. |
