Technical Basis
A review of available sources identified multiple exposure limits (TLV-C, PEL-C, REL-C), a rat LCLo, 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 rat LCLo was selected as the TEEL-3 basis and was scaled to a 60-minute equivalent using the ten Berge equation (Section 3.3.4). Although there is an LOC for this chemical, it was not selected as the TEEL-2 since the value was greater than the TEEL-3 derived from rat LCLo toxicity data. Instead, the TLV-C was selected as the TEEL-2. The TEEL-1 was derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TLV-C (0.1 ppm)
• TEEL-3 = Rat LCLo (19 ppm/4H)
This review generated TEEL values that are consistent with Rev. 29A*.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TLV-C (0.1 ppm)
• TEEL-3 = Rat LCLo (19 ppm/4H)
