Technical Basis
A review of limited sources identified a mouse intraperitoneal LD50 that was selected as the TEEL-3 basis and evaluated using factors in Tables 3.2, 3.3, and 3.4. 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 = Mouse intraperitoneal LD50 (810 mg/kg)
This review generated TEEL values inconsistent with Rev 29A. In Rev. 29A the TEEL-3 basis was a rat oral LD50 not found during the current review. Instead, a mouse intraperitoneal LD50 is the current TEEL-3 basis. The TEEL-2 and TEEL-1 methodology remain consistent with the change in values due to the change in the TEEL-3 basis.
