Technical Basis
A review of available sources identified exposure limits (WEEL-TWA) 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 toxicity data, a dog oral LD50, was selected as the TEEL-3 basis. The TEEL-2 value was derived according to Table 3.5. The WEEL-TWA was selected as the TEEL-1 basis.
• PAC-1 = TEEL-1 = WEEL-TWA (5 mg/m3) x 3
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = Dog oral LD50 (1 g/kg)
This review generated PAC values 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.
