Technical Basis
A review of available sources identified a rat LC50 and level of concern (LOC). Data sources were selected according to the hierarchy listed in Table 3.1. The four-hour rat LC50 was selected as the TEEL-3 basis; it was evaluated using factors in Tables 3.2, 3.3, and 3.4 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 TEEL-1 value was derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = LOC (0.0022 g/m3)
• TEEL-3 = Rat LC50 (220 mg/m3/4H)
This review generated TEEL values that are consistent with Rev. 29A*.
