Technical Basis
A review of available sources identified exposure limits (TLV-TWA) and 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. The TLV-TWA was selected as the TEEL-1 basis (Table 3.5). Several rat oral LD50 were compared; of these, only two doses (6560 and 6600 mg/kg) did not result in a TEEL-1 > TEEL-2. The most recent dose (6600 mg/kg) was selected as the TEEL-3 basis. TEEL-2 values were derived according to Table 3.5.
• TEEL-1 = TLV-TWA (10 ppm) x 3
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat oral LD50 (6600 mg/kg)
This review generated TEEL values consistent with Rev. 29A.
