Technical Basis
A review of available sources identified acute toxicity data (LD50, LC50, LDLo) for various species and routes, and exposure limits (OEL-TWAs, OEL-STEL). 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 most preferred exposure data, a 1-hour rat LC50, was selected as the TEEL-3 basis. TEEL-2 was derived according to Table 3.5. The OEL-STEL (Denmark) was selected as the TEEL-1.
• PAC-1 = TEEL-1 = OEL-STEL (Denmark; 6 mg/m3)
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = Rat LC50 (5200 mg/m3/1H)
This review generated PAC-2 and PAC-3 values consistent with Rev. 29A. The current PAC-1 value is inconsistent with Rev. 29A. The Rev. 29A TEEL-1 basis was the OEL-TWA (United Kingdom), while the current TEEL-1 is an OEL-STEL (more preferred data according to Table 3.1 and Table 3.5 *note).
