Technical Basis
A review of available sources identified a LOC and numerous acute toxicity data (LC50, LD50) for various routes and species. 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 lowest rat LC50 was selected as the TEEL-3 basis and scaled to a 60-minute equivalent using the ten Berge equation (Section 3.3.4). Although the LOC (0.001 g/m3) was considered as a TEEL-2, it was not selected because (1) LOCs are based on exposure limits before 1987, which appear to have been discontinued since no current exposure limits can be found and (2) it would result in a TEEL-2 higher than the TEEL-3. 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 LC50 (7 µg/L/4H)
This review generated TEEL values consistent with Rev. 29A.*
