Technical Basis
A review of limited sources identified a rat oral LD50 that was selected as the TEEL-3 basis and evaluated using factors in Tables 3.2, 3.3, and 3.4. TEEL-2 and TEEL-1 values were derived according to Table 3.5.
• PAC-1 = TEEL-1 = TEEL-2/11
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = Rat oral LD50 (1260 mg/kg)
This review generated PAC values consistent with Rev. 29A*.
