Technical Basis
A review of available sources identified rat oral LD50 acute toxicity data and a Level of Concern (LOC). 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 oral LD50 (7200 μg/kg) was evaluated as potential TEEL-3 source, however, when considering the preferable LOC as the TEEL-2, the rat oral data resulted in a TEEL-3 < TEEL-2; therefore, it was not selected as the TEEL-3 basis. The LOC was selected as the TEEL-2. TEEL-1 and TEEL-3 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = LOC (0.0072 g/m3)
• TEEL-3 = TEEL-2 x 6
This review generated TEEL values consistent with Rev. 29A*.
