Technical Basis
A review of available sources identified the following mouse and rat acute oral toxicity data (LD50). 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. The most preferred species, the rat oral LD50, was selected as the TEEL-3 basis. The 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 (2050 mg/kg)
This review generated a TEEL-3 value, source, and methodology consistent with Rev. 29A. TEEL-2 and TEEL-1 values are inconsistent with Rev. 29A. The Rev. 29A TEEL-2 basis was a rat TDLo not found in the review; instead, the TEEL-2 value was derived from the TEEL-3 (Table 3.5). The Rev. 29A and current TEEL-1 use the same methodology, with differences due to the change in TEEL-2.
