Technical Basis
A review of available sources identified the following: a TLV-TWA, LOC, LD50 toxicity data for numerous species and routes of administration, and rat LC50 toxicity data. 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 based on preferability of Table 3.1 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, and the TLV-TWA as the TEEL-1 basis.
• TEEL-1 = TLV-TWA (0.1 mg/m3) x 3
• TEEL-2 = LOC
• TEEL-3 = Rat LC50 (85 mg/m3/4H)
This review generated TEEL values that are consistent with Rev. 29A.
• TEEL-1 = TLV-TWA (0.1 mg/m3) x 3
• TEEL-2 = LOC
• TEEL-3 = Rat LC50 (85 mg/m3/4H)
This review generated TEEL values that are consistent with Rev. 29A.
