Technical Basis
A review of available data sources identified the following: LD50 toxicity values for mouse, rat, and human oral route exposures. Each was evaluated using the guidelines for calculating equivalent values and a duration of 1 day was assumed, when not specified. Toxicity data were evaluated for their relative preference ranking (Section 3.3.2, Table 3.1). Although the human data (1984) ranked higher in preference, a rat, oral (2001) toxicity value was selected because it is the most current (Section 3.3.1). TEEL-2 and TEEL-1 estimates were calculated from the 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 (> 3.2 g/kg)
This review generated TEEL values consistent with those published in Rev. 29A.
