Technical Basis
A review of available sources identified the following: mouse LCLo, rat LD50 and LC50 acute toxicity data and a TLV-TWA. 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 most preferred route and species, the rat LC50, was selected as the TEEL-3 basis. The TEEL-2 was derived according to Table 3.5. The TLV-TWA was selected as the TEEL-1 basis.
• TEEL-1 = TLV-TWA (0.005 ppm) x 3
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat LC50 (180 ppm/6H)
This review generated TEEL values that were consistent with those in Rev. 29A.
• TEEL-1 = TLV-TWA (0.005 ppm) x 3
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat LC50 (180 ppm/6H)
This review generated TEEL values that were consistent with those in Rev. 29A.
