Technical Basis
A review of limited sources identified oral acute toxicity data (LD50). 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. The mouse intraperitoneal was determined to be the most reliable source (Section 3.3.1) and it 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 intraperitoneal LD50 (53 mg/kg)
This review generated TEEL values that are consistent with Rev. 29A*.
