Technical Basis
A review of available sources identified the following: an LOC and acute inhalation and intravenous 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. Inhalation exposures were scaled to 60-minute equivalents using the ten Berge equation (Section 3.3.4). The mouse 2-hr LC50 was selected as the TEEL-3 basis because it was 1) the more recent study, 2) the closest to a 60-minute duration (Section 3.3.2,) and 3) the most preferred route and type (Table 3.1). The LOC was selected as TEEL-2. TEEL-1 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = LOC (0.0009 g/m3)
• TEEL-3 = Mouse, LC50 (92 mg/m3/2H)
This review generated TEEL values that are consistent with Rev. 29A.
