Technical Basis
A review of available sources identified the following: mouse and rat LD50 acute toxicity data for intravenous, intraperitoneal, and oral routes. Data sources were selected according to the hierarchy listed in Table 3.1. Toxicity data were selected according to type of exposure, species, and route according to the hierarchies stated in Sections 3.3.1, 3.3.2, 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 = Rat oral LD50 (380 mg/kg)
This review generated a TEEL-2 and TEEL-1 values that are more conservative than Rev.29A and a TEEL-3 value consistent with Rev. 29A. The Rev. 29A TEEL-2 basis, a rat oral TDLo, was not found during the current review. The current TEEL-2 was instead derived from the TEEL-3, according to Table 3.5. The Rev. 29A and current TEEL-1 methodology is consistent.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat oral LD50 (380 mg/kg)
This review generated a TEEL-2 and TEEL-1 values that are more conservative than Rev.29A and a TEEL-3 value consistent with Rev. 29A. The Rev. 29A TEEL-2 basis, a rat oral TDLo, was not found during the current review. The current TEEL-2 was instead derived from the TEEL-3, according to Table 3.5. The Rev. 29A and current TEEL-1 methodology is consistent.
