Technical Basis
A review of available sources identified the following: LD50 (mouse, rat) for intraperitoneal, intravenous, 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. Of the available toxicity data, the most preferred, a rat oral LD50, was selected as the TEEL-3 basis. TEEL-2 and TEEL-1 values were calculated according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat Oral LD50 (2390 mg/kg)
Although identical in value and consistent in methodology, the current TEEL basis is a rat oral LD50 (published 1978) instead of a rat intraperitoneal LD50 (published in 1950). This review generated TEEL values that are consistent with those in Rev. 29A.
