Technical Basis
A review of available data sources identified the following: a rat oral LD501 toxicity source that was selected as the most preferred species and route 2. TEEL-2 and TEEL-1 values were calculated from this TEEL-3 value, according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Estimated from rat, oral LD50 (90 mg/kg)
The review generated TEEL values that were consistent with those found in Rev 29A, due to the same starting point.
