Technical Basis
A review of available sources identified rat and mouse acute toxicity data (LD50, LC50) for inhalation and oral routes, and LOC. 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 species and route, a four-hour rat LC50, was selected as the TEEL-3 basis and was scaled to a 60-minute equivalent using the ten Berge equation (Section 3.3.4). The LOC was selected as the TEEL-2. The TEEL-1 value was derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = LOC (0.0025 g/m3)
• TEEL-3 = Rat inhalation LC50 (420 mg/m3/4H)
This review generated TEEL values that are consistent with Rev. 29A*.
