Technical Basis
A review of available sources identified animal 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 based on 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 TEEL-3 continues to be based on rat LC50, which was scaled to a 60-minute equivalent using the ten Berge equation (Section 3.3.4). TEEL-2 and TEEL-1 values were calculated according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat 4-hr LC50 (1974 ppm)
This review has generated TEEL-3 and TEEL-2 values consistent with those in Rev. 29A. The reported inconsistency between TEEL-1 in units of mg/m3 can be attributed to rounding methodology (rounding before or after conversion).
