Technical Basis
A review of available sources identified mouse and rat acute toxicity data (LD50) for oral and intraperitoneal 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. The most preferred route and species toxicity data 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 = Mouse intraperitoneal LD50 (78 mg/kg)
This review generated TEEL values that are consistent with Rev. 29A*.
