Technical Basis
A review of limited sources identified mouse oral LD50 toxicity data that was selected as the TEEL-3 basis and evaluated using factors in Tables 3.2, 3.3, and 3.4. TEEL-1 and TEEL-2 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 = Mouse oral LD50 (3250 mg/kg)
This review generated PAC values inconsistent with Rev. 29A. The Rev. 29A TEEL-3 basis was a rat oral LD50 that was not identified during this review; instead, the current TEEL-3 is based on mouse oral LD50 toxicity data. The Rev. 29A and current TEEL-2 and TEEL-1 methodology remains consistent, with differences in values due to the change of the TEEL-3 basis.
