Technical Basis
A review of available sources identified rat and mouse acute toxicity data (LD50, LDLo) for intraperitoneal and intravenous exposures. 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 LD50 of the most preferred species and route, a rat intraperitoneal LD50, was selected as the TEEL-3 basis. 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 intraperitoneal LD50 (230 mg/kg)
This review generated PAC values that are consistent with Rev. 29A*.
