Technical Basis
A review of available sources identified the following: rat LCLo, rat and mouse oral LD50 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 LC50 was scaled to 60-minute equivalent using the ten Berge equation (Section 3.3.4). TEEL-2 and TEEL-1 values were derived from Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat LCLo (2000 ppm/4H)
TEEL-3 concurs with Rev29A. The Rev. 29A TEEL-2 basis, a TDLo, was not found during current research. The method of deriving the TEEL-1 (Table 3.5) was consistent but was lower due to the change in TEEL-2 basis.
