Technical Basis
A review of limited sources identified rat acute toxicity data (oral LDLo¬) that was selected as the TEEL-3 basis and evaluated using factors in Tables 3.2, 3.3, and 3.4. The toxicity dose was reported in units of µL/kg, which was converted to a mg/kg (density = 2.007 g/mL at 25°C). TEEL-2 and TEEL- values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat oral LDLo (50 µL/kg; converted to 100.35 mg/kg)
This review generated TEEL 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.
