Technical Basis
A review of available sources identified the following: TLV-STEL and acute toxicity data (LC50, LD50) for rat and mouse. 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 two LC50 exposures were examined; the 30-minute duration exposure was selected as the TEEL-3 basis because it is closer to 60 minutes;, and it was scaled using the ten Berge equation (Section 3.3.4). The TEEL-2 value was calculated according to Table 3.5 and the TLV-STEL was selected as the TEEL-1.
• TEEL-1 = TLV-STEL (0.2 ppm)
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat LC50 (10,000 mg/m3/30-min)
This review generated a TEEL-1 that is consistent with Rev. 29A. The TEEL-2 and TEEL-3 values are more conservative than those in Rev. 29A due to a different TEEL-3 basis. The Rev. 29A basis, reported as a 2-hr LC50, was not found during current research.
