Technical Basis
A review of available data sources identified the following: LC50 and LD50 toxicity data for inhalation and oral exposures. 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 rat LC50 was the most preferred route and species and was selected as the TEEL-3 basis. The LOC was selected as the TEEL-2. TEEL-1 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = 4.3 mg/m3 LOC (0.0043 g/m3)
• TEEL-3 = Rat LC50 (430 mg/m3/2H)
This review generated TEEL values that are consistent with Rev. 29A.
