Technical Basis
A review of available sources identified rat intraperitoneal LDLo and mouse intravenous LD50 acute toxicity data. 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. When estimating the TEEL-3 values, the rat LDLo and mouse LD50 resulted in identical TEEL values; therefore, the mouse intravenous LD50 was selected as the TEEL-3 basis since it is the most preferred source (LD50 > LDLo). The 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 intravenous LD50 (180 mg/kg)
This review generated TEEL values consistent with Rev. 29A.
