Technical Basis
A review of available sources identified AEGLs for this chemical. The AEGLs were selected due to their priority among Protective Action Criteria (Section 1).
• PAC-1 = AEGL-1
• PAC-2 = AEGL-2
• PAC-3 = AEGL-3
This review generated PAC values consistent with Rev. 29A*.
• PAC-1 = AEGL-1
• PAC-2 = AEGL-2
• PAC-3 = AEGL-3
This review generated PAC values consistent with Rev. 29A*.
