Technical Basis
A review of available sources identified the following: LC50, LCLo, and LD50 (mouse, rat) for oral routes. Data sources were reviewed according to the hierarchy listed in Table 3.1. Toxicity data were selected according to source credibility/age, 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. Although the LC50 is typically preferable according to the data hierarchy, in this case it was not selected due to unverifiable source. The LCLo was scaled to a 60-minute equivalent using the ten Berge equation (Section 3.3.4). The 6-hr rat LCLo was selected as the TEEL-3 basis, as the most preferred combination of source credibility, route, and species. TEEL-2 and TEEL-1 values were calculated according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat 6-hr LCLo (3100 mg/m3)
This review generated TEEL values consistent with those in Rev 29A.
