Technical Basis
A review of available sources identified: guinea pig and rat LD50¬ acute toxicity data. 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 dose, most preferred species and route, a rat oral LD50, was selected as the TEEL-3 basis. 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 (612 mg/kg)
This review generated TEEL values inconsistent with those in Rev. 29A. The Rev. 29A and current TEEL-3 bases are both rat oral LD50¬; however, the current TEEL-3 basis was selected because it was a more robust study (Section 3.3.1), resulting in a slightly more conservative TEEL-3 value. The Rev. 29A TEEL-2 basis was a rat TCLo that was not found during the current review, so it was instead derived from the TEEL-3 (Table 3.5). The Rev. 29A and current TEEL-1 methodology are consistent, with differences due to the change in TEEL-2 value.
