Technical Basis
A review of available sources identified the rat acute toxicity data (LC50, LD50). 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 most preferred route, a rat LC50, was selected as the TEEL-3 basis and 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 LC50 (=> 2.95 mg/L/4H)
This review generated TEEL-3 and TEEL-2 values consistent with Rev. 29A. The Rev. 29A and current TEEL-1 methodology are the same, derived from the TEEL-2; it’s unclear why the TEEL-1 values are inconsistent.
