Technical Basis
A review of available sources identified rat and mouse acute toxicity data (LD50). Data sources were selected according to the hierarchy listed in Table 3. 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 most preferred route and species, a 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 (208 mg/kg)
This review generated TEEL values that are consistent with Rev. 29A.
