Technical Basis
A review of available sources identified acute toxicity data (LD50, LC50) for various species (rat, mouse, guinea pig) and routes (inhalation, oral). 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. Although inhalation is the most preferred route, the acute inhalation data (LC50) reference could not be verified; therefore, it was not selected for TEEL development (Section 3.3.1). Instead, the next most preferred species LD50, rat oral 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 oral LD50 (1250 mg/kg)
This review generated PAC values consistent with Rev. 29A.
