Technical Basis
A review of limited sources identified mouse intravenous LD50 acute toxicity data which was selected as the TEEL-3 basis and evaluated using factors in Tables 3.2, 3.3, and 3.4. 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 = Mouse intravenous LD50 (180 mg/kg)
This review generated TEEL values that are consistent with Rev. 29A*.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Mouse intravenous LD50 (180 mg/kg)
This review generated TEEL values that are consistent with Rev. 29A*.
