Technical Basis
A review of available sources identified the following: rat oral LD50 and rat LC50. Toxicity data were selected according to type of exposure, species, and route based on 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 LC50 was not selected because the duration of exposure was not reported. Instead, the rat oral LD50 was selected as the TEEL-3 basis. 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 (160 mg/kg)
This review generated TEEL values that are consistent with those in Rev. 29A. There are no changes to the TEEL results or methods, therefore the difference in TEEL-1 may be attributed to rounding.
