Technical Basis
A review of available sources identified the following: rat and mouse LD50 toxicity data for oral, intravenous, subcutaneous, 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 rat oral LD50 data (2600 mg/kg) was selected as the TEEL-3 basis as it was the most preferred species and route. TEEL-1 and TEEL-2 values were calculated according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat oral LD50 (2600 mg/kg)
This review generated TEEL values that are inconsistent with Rev. 29A. The Rev. 29A TEEL-3 was also based on rat oral LD50 toxicity data, however the dosage used in that revision could not be found. Additionally, Rev. 29A used rat intraperitoneal TDLo data for the TEEL-2 basis, but that data was also not found for this review.
