Technical Basis
A review of available sources identified LD50 toxicity data for various routes (dermal, oral) and species (rat, mouse, rabbit), and a LOC. 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 preferred species and route data, a rat oral LD50, was selected as the TEEL-3 basis. The LOC was selected as the TEEL-2. The TEEL-1 value was derived according to Table 3.5.
• PAC-1 = TEEL-1 = TEEL-2/11
• PAC-2 = TEEL-2 = LOC (0.045 g/m3)
• PAC-3 = TEEL-3 = Rat oral LD50 (6500 mg/kg)
This review generated PAC values consistent with Rev. 29A*.
