Technical Basis
A review of available sources identified oral LD50 toxicity data for multiple species 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 data, 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 (0.001 g/m3)
• PAC-3 = TEEL-3 = Dog oral LD50 (8100 µg/kg => 8.1 mg/kg)
This review generated PAC values that are consistent with Rev. 29A*.

PAC values marked with a subscript "A" correspond to 60-minute AEGL values.
PAC values marked with a subscript "E" correspond to ERPG values.
PAC values marked by * are >= 10% lower explosive limit (LEL) but < 50% LEL.
PAC values marked by ** are > 50% LEL but < 100% LEL.
PAC values marked by *** are >= LEL.
