Technical Basis
A review of available sources identified the following toxicity exposures: LC and LD50 (rat, mouse) for intraperitoneal and oral routes. 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 LC was not selected because the dose description did not provide lethality effect (as in an LC50 or LCLo) and it was therefore determined to be an incomplete/unreliable record (Section 3.3.1). Instead, the lowest available rat oral LD50 was selected as the TEEL-3 basis. TEEL-2 or TEEL-1 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat oral LD50 (5500 mg/kg)
This review generated TEEL values consistent with those in Rev. 29A
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat oral LD50 (5500 mg/kg)
This review generated TEEL values consistent with those in Rev. 29A
