Technical Basis
A review of available sources identified the following: LC50 (mouse, rat) and rat LD50 acute 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. Inhalation exposures were scaled to 60-minute equivalents using the ten Berge equation (Section 3.3.4). Although rat is a more preferred species, the mouse LC50 was selected as the TEEL-3 basis because 1) the rat LC50 available on ECHA did not report deaths and 2) a lower duration (2H vs. 4H) exposure is preferred (Section 3.2.2). TEEL-2 and TEEL-1 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = LC50 data (4000 mg/m3/2H)
This review generated TEEL-3 values that are consistent with Rev. 29A. The Rev. 29A TEEL-2 basis was a rabbit TCLo that was not found in the current review; instead, the TEEL-2 derived from the TEEL-3 (Table 3.5). The Rev. 29A and current TEEL-1 methodology are consistent, with differences due to the change in TEEL-2.
