Technical Basis
A review of available sources identified a LOC and LD50 acute toxicity data for several 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. A dog intravenous LD50 and rat oral LD50 were evaluated for the TEEL-3. The dog data was selected as the TEEL-3 basis since it was the highest priority species, and because the rat data resulted in an overly conservative TEEL-3 value. The LOC was selected as the TEEL-2. The TEEL-1 value was derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = LOC (0.001 g/m3)
• TEEL-3 = Dog intravenous LD50 (5 mg/kg)
This review generated TEEL values that are consistent with Rev. 29A*.
