Technical Basis
A review of limited sources identified dog intravenous LDLo toxicity data that was selected as the TEEL-3 basis and evaluated using factors in Tables 3.2, 3.3, and 3.4. The TEEL-1 and TEEL-2 values were calculated according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Dog intravenous LDLo (17 mg/kg)
This review generated TEEL values that are consistent with Rev. 29A*.
