Technical Basis
A review of available sources identified the following toxicity a mouse oral LD50 toxicity data as the most preferred, with consideration of source age, credibility, dose variability, species/route preferability, and conservatism. This LD50¬ was selected as the TEEL-3 basis. TEEL-2 and TEEL-1 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/6
• TEEL-2 = TEEL-3/11
• TEEL-3 = Mouse oral LD50 (20700 mg/kg)
This review generated TEEL values that were consistent with those in Rev. 29A.
