Technical Basis
A review of available sources identified the following: LD50 (rat, mouse) for intraperitoneal and oral 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. Conservatism was also considered. The mouse 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 = Mouse oral LD50 (2120 mg/kg)
This review generated TEEL values that are inconsistent with those in Rev. 29A. The Rev. 29A TEEL-3 basis was a rat oral LD50 that was not found during current research. TEEL-2 and TEEL-1 values were derived using the same methodology, with differences due to the change in TEEL-3 basis.
