Technical Basis
A review of available sources identified exposure limits (TLV-TWA, LOC) and acute toxicity data (LC50, LD50). 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 LC50 was selected as the TEEL-3 basis and was scaled to 60-minute equivalent using the ten Berge equation (Section 3.3.4). The LOC was selected as the TEEL-2. The TLV-TWA was selected as the TEEL-1 basis.
• TEEL-1 = TLV-TWA (0.005 mg/m3) x 3
• TEEL-2 = LOC (0.0003 g/m3)
• TEEL-3 = Rat LC50 (200 mg/m3/5H)
This review generated TEEL-3 and TEEL-1 inconsistent with Rev. 29A. The Rev. 29A and current TEEL-2 values and source are consistent. The Rev. 29A TEEL-3 and TEEL-1 were derived from this TEEL-2, while the current TEEL-3 basis is a rat LC50 toxicity data, and the TEEL-1 basis is a TLV-TWA.
