Technical Basis
A review of available sources identified rat acute toxicity data (LD50, LC50) for inhalation and oral exposures, and a Level of Concern (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 exposure type, 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 basis. The TEEL-1 value was derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = LOC (0.0033 g/m3)
• TEEL-3 = Rat LC50 (330 mg/m3/4H)
This review generated TEEL values consistent with Rev. 29A*.
