Technical Basis
A review of limited sources identified a rat oral LD50 that was selected as the TEEL-3 basis 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 (302 mg/kg)
This review generated PAC values inconsistent with Rev. 29A. The Rev. 29A TEEL-3 basis was an HHR=3 (Section 3.4.5). Instead, analysts selected available acute toxicity data, a rat oral LD50 as the TEEL-3 basis. The Rev. 29A and current TEEL-2/TEEL-1 use the same methodology, with differences due to the change in TEEL-3.
