Technical Basis
A review of available sources identified a LOC and acute toxicity data (LD50) for several species and 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 preferred species and route, a dog 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 (0.0037 g/m3)
• PAC-3 = TEEL-3 = Dog oral LD50 (23 mg/kg)
This review generated PAC-2 and PAC-1 values consistent with Rev. 29A and a PAC-3 inconsistent with Rev. 29A. The Rev. 29A and current TEEL-3 basis are consistent (dog oral LD50); considering this, differences in the TEEL-3 values may be due to different reported doses. The current TEEL-3 basis is the available dog oral LD50 dose.
