Technical Basis
A review of available sources identified the following: LCL0 and LD50 animal 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. The LCLo was scaled to 60-minute equivalent using the ten Berge equation (Section 3.3.4). The LCLo was the most preferred species and route, therefore it was selected as the TEEL-3 basis. 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 =Rat 4-hr LCLo (125 ppm)
This review generated TEEL-3 values consistent with those in Rev.29A. The Rev. 29A TEEL-2 basis, a mouse TCLo, was not found during current research and the TEEL-3 derivation (Table 3.5) resulted in a more conservative TEEL-2 and TEEL-1 due to this change in basis.
