Technical Basis
A review of available sources identified a rat oral acute toxicity study that was selected as the TEEL-3 basis and evaluated using factors in Tables 3.2, 3.3, and 3.4. The 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 oral LD50 (>2000 mg/kg)
This review generated TEEL values inconsistent with Rev. 29A. The Rev. 29A TEEL-3 basis was mouse intraperitoneal LDLo not found during the current review. Analysts instead use available rat oral LD50 data as the TEEL-3 basis. The Rev. 29A and current TEEL-2/TEEL-1 use the same methodology, with differences due to the change in TEEL-3.
