Technical Basis
A review of available sources identified the rat acute 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 lowest rat oral acute toxicity data was selected as the TEEL-3 value. 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 (238 mg/kg)
This review generated TEEL-2 and TEEL-1 values inconsistent with Rev. 29A. The Rev. 29A and current TEEL-3 values, source, and methodology are consistent. The Rev. 29A TEEL-2 basis was a rat TDLo not found during the review; instead, the TEEL-2 was derived from the TEEL-3 (Table 3.5). The Rev. 29A and current TEEL-1 used the same methodology (Table 3.5), with differences due to the change in TEEL-2.
