Technical Basis
A review of available sources identified rat acute toxicity data (LD50) for several routes. Data sources were selected according to the hierarchy listed in Table 3.1. Toxicity data were selected according to type of exposure, species, and route according to the hierarchies stated in Sections 3.3.1, 3.3.2, and evaluated using factors in Tables 3.2, 3.3, and 3.4. The most conservative rat oral LD50 was selected as the TEEL-3 basis (Section 3.3.1). 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 (3154 mg/kg)
This review generated PAC values consistent with Rev. 29A*.
