Technical Basis
A review of available sources identified acute toxicity data (LD50, LDLo) for multiple species and routes. 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. 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 = LD50 rat oral (4200 mg/kg)
This review generated TEEL-2 and TEEL-1 values that are inconsistent with Rev. 29A, and a TEEL-3 value consistent with Rev. 29A. The Rev. 29A TEEL-2 basis was a rabbit oral TDLo not found during this review. Instead, the TEEL-2 was derived from the TEEL-3 (Table 3.5), also resulting in a change in TEEL-1.
