Technical Basis
A review of available sources identified the following: mouse and rat LD50 toxicity data. Data sources were selected according to the hierarchy listed in Table 3.1. Data were evaluated using factors in Tables 3.2, 3.3, and 3.4. The rat 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 = Rat oral LD50 (2078 mg/kg)
This review generated TEEL values that are consistent with those in Rev. 29A.
