Technical Basis
A review of available sources identified numerous LC50 and LD50 toxicity data for rat and mouse, an OEL-STEL, 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 more preferred species and route, a 120-minute rat LC50, was selected as the TEEL-3 basis and was scaled to 60-minute equivalent using the ten Berge equation (Section 3.3.4). A LOC was selected as the TEEL-2. A short-term (15-minute) international Occupational Exposure Limit (OEL) was selected as the TEEL-1.
• TEEL-1 = OEL-STEL (Austria)
• TEEL-2 = LOC (0.023 g/m3)
• TEEL-3 = Rat LC50 (61 ppm/2h)
This review generated TEEL-3 and TEEL-2 values that are consistent with Rev. 29A. The Rev. 29A TEEL-1 was derived according to Table 3.5, while the current TEEL-1 is a short-term exposure limit, a more preferred TEEL source.
