Technical Basis
A review of available sources identified acute toxicity data (LDLo, LD50). Data sources were selected according to the hierarchy listed in Table 3.1. Toxicity data were selected according to type of exposure, species, and route according to the hierarchies stated in Sections 3.3.1, 3.3.2, and evaluated using factors in Tables 3.2, 3.3, and 3.4. Based on source reliability, route and species, a rat oral LD50 was selected as the TEEL-3 basis. TEEL-2 and TEEL-1 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat, oral LD50 (3750 mg/kg)
This review generated TEEL values that are inconsistent with those found in Rev. 29A. The Rev. 29A and current bases are consistent, a rat oral LD50; however, the acute toxicity dose resulting in Rev. 29A TEEL values was not found during current research.
