Technical Basis
A review of available sources identified multiple rat and mouse LD50 toxicity data for oral and intraperitoneal exposures. 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 LD50 of the most preferred species and route, a 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 (725 mg/kg)
This review generated TEEL values that are consistent with Rev. 29A*.
