Technical Basis
A review of available sources identified a LOC and acute toxicity data (LD50) for several routes and species. 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 LOC was selected as the TEEL-2. Acute toxicity data were evaluated, resulting in TEEL-3 values that ranged from 0.07 to 22 mg/m3. Considering this, analysts prioritized the exposure limit as a TEEL-3 basis. TEEL-3 and TEEL-1 values derived according to Table 3.5.
• PAC-1 = TEEL-1 = TEEL-2/11
• PAC-2 = TEEL-2 = LOC (0.001 gm/m3)
• PAC-3 = TEEL-3 = TEEL-2 x 6
This review generated PAC values consistent with Rev. 29A.
