Technical Basis
A review of available sources identified the following: mouse and rat LD50 acute toxicity data. Data sources were selected according to the hierarchy listed in Table 3.1. Toxicity data was 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 and route, the rat oral LD50, was selected as the TEEL-3 basis. TEEL-1 and TEEL-2 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat oral LD50 (7110 mg/kg)
This review generated TEEL-3 and TEEL-2 values consistent with those in Rev. 29A. The Rev. 29A and current TEEL-2 bases resulting in identical values, however the Rev. 29A basis was a rat TDLo, while the current TEEL-2 was derived from the TEEL-3. The Rev. 29A and current TEEL-1 were derived with the same methodology (Table 3.5), with the minor difference in values due to the change in TEEL-2 basis.
