Technical Basis
A review of available sources identified the following: a rat 240-min LC50 toxicity data. This source was selected according to the hierarchy listed in Table 3.1. Toxicity data was evaluated using the type of exposure, species, and route preferability stated in Sections 3.3.1, and 3.3.2. The concentration is scaled to a 60-minute equivalent using the ten Berge equation (Section 3.3.4). 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 240-min LC50 (500 ppm)
This review generated TEEL values that are consistent with Rev. 29A.
