Technical Basis
A review of limited sources identified acute toxicity data (LDLo). Data sources were selected according to the hierarchy listed in Table 3.1. Toxicity data were evaluated using factors in Tables 3.2, 3.3, and 3.4. The most preferred species and route, a dog intravenous LDLo, was selected as the TEEL-3 basis. TEEL-2 and TEEL-1 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Dog intravenous LDLo (10 mg/kg)
This review generated TEEL 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.
