Technical Basis
A review of available sources identified the following: rat and mouse LD50 toxicity data for oral, skin, and intravenous routes. The rat oral LD50 was selected as the TEEL-3 basis based on the hierarchies stated in Sections 3.3.1 and 3.3.2. It was calculated using factors in Tables 3.2, 3.3, and 3.4. TEEL-2 and TEEL-1 values were calculated according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = rat oral LD50 (>5 g/kg)
This review generated TEEL values that are less conservative and inconsistent with those in Rev. 29A. The Rev. 29A TEEL-3 basis was a rat oral LDLo data, while the current values are based on rat oral LD50 data. LD50 data is preferred over LDLo data according to the handbook.
