Technical Basis
A review of available sources identified the following: a WEEL-STEL and rat LD50 toxicity data. These sources were selected according to the hierarchy listed in Table 3.1. Toxicity data was evaluated using the type of exposure, species, and route preferability stated in Sections 3.3.1, and 3.3.2. A rat oral LD50 is selected for TEEL-3 development, based on the preferabilities discussed above and source credibility (SAX, 2004). TEEL-2 values were derived according to Table 3.5. A WEEL-STEL was selected as the TEEL-1.
• TEEL-1 = WEEL-STEL
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat oral LD50 (1300 mg/kg)
This review generated TEEL values consistent with those in 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.
