Technical Basis
A review of available sources identified numerous animal toxicity data. 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. The most preferred 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 (1,410 mg/kg)
Current and Rev. 29A TEEL-3 methodology, basis, and values are consistent. This review generated TEEL-2 and TEEL-1 values inconsistent with Rev. 29A. The Rev. 29A basis was a TCLo found in current research to have toxicity endpoints inappropriate for TEEL development (slight eye irritation). Instead, the current review is based on alternate TEEL methodology outlined in Table 3.5.
