Technical Basis
A review of limited sources identified a rat inhalation LCLo that was selected as the TEEL-3 basis and evaluated using factors in Tables 3.2, 3.3, and 3.4. TEEL-1 and -2 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat inhalation LCLo (750 mg/m3/4H)
This review generated TEEL values that are consistent with Rev. 29A*.
