Technical Basis
A review of available sources identified the following: a WEEL-C and rat 4-hr LC50.
Data sources were selected according to the hierarchy listed in Table 3.1. The toxicity data was evaluated using factors in Tables 3.2, 3.3, and 3.4 and scaled to a 60-minute equivalent using the ten Berge equation (Section 3.3.4). TEEL-1 values were calculated according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 =WEEL-C (1 mg/m3)
• TEEL-3 =Rat 4-hr LC50 (960 mg/m3)
This review generated TEEL values consistent with those in Rev. 29A.
