Technical Basis
A review of available sources identified the following: LC50, LCLo, and LD50 (rat, mouse, rabbit) 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. Inhalations doses were scaled to 60-minute equivalents using the ten Berge equation (Section 3.3.4). The most preferred species and route, a rat LC50, was selected as the TEEL-3 basis. 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 LC50 (2052 mg/m3/4H)
This review generated TEELs inconsistent with those in Rev. 29A. The Rev. 29A TEEL-3 basis was a rat LCLo, a less preferred basis (LC50 > LCLo, Table 3.1). The Rev. 29A and current TEEL-2 and TEEL-1 methodology are consistent, with differences due to the change in TEEL-3.
