Technical Basis
A review of available sources identified acute toxicity data (LD50, LDLo) for various species and routes, and exposure limits (IDLH, TWAs, OEL-STELs). 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 1990/1994 IDLH was selected as the TEEL-3. TEEL-2 was derived according to Table 3.5. The most conservative OEL-STEL, Romania, was selected as the TEEL-1.
• PAC-1 = TEEL-1 = OEL-STEL (5 mg/m3, Romania)
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = IDLH (1990 & 1994) (300 mg/m3)
This review generated a PAC-3 value consistent with Rev. 29A and inconsistent PAC-2 and PAC-1 values. The Rev. 29A and current TEEL-3 source and methodology are consistent. The Rev. 29A TEEL-2 basis was a 6-hour rat TCLo not found in the current review; instead, the current TEEL-2 was derived according to Table 3.5. The Rev. 29A TEEL-1 basis was the TLV-TWA, while the current TEEL-3 is an OEL-STEL (Romania), a more preferred exposure limit (see Table 3.5, Note).
