Technical Basis
A review of available sources identified the following: rat LD50 and LCLo acute 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. The LCLo was scaled to 60-minute equivalent using the ten Berge equation (Section 3.3.4). The most preferred route and species, the rat LC¬Lo, was selected as the TEEL-3 basis. 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 LCLo (250 ppm/4H)
This review generated TEEL values that are consistent with those in Rev 29A
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat LCLo (250 ppm/4H)
This review generated TEEL values that are consistent with those in Rev 29A
