Technical Basis
A review of available sources identified acute toxicity data (LD50) for various species (rat, rabbit) and routes (oral, dermal). 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. Rat oral toxicity study was selected for TEEL calculations. 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 = Rat oral LD50 (3900 mg/kg)
This review generated PAC values consistent with Rev. 29A*.
