Technical Basis
A review of limited sources identified mouse intraperitoneal 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-2 and TEEL-1 values were calculated according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Mouse intraperitoneal LDLo (100 mg/kg)
This review generated a TEEL-3 source and value consistent with Rev. 29A. The Rev. 29A TEEL-2 basis was rat oral TDLo that was not found in this review; instead, the TEEL-2 and TEEL-1 values were derived according to Table 3.5.
