Technical Basis
A review of available sources identified rat acute toxicity data (LD50, LC50). Although the more preferred route, the inhalation data was an incomplete record (no duration) for a wide range, therefore it was determined to be unsuitable for TEEL development. Instead, the rat oral LD50 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 = Rat oral LD50 (305 mg/kg)
This review generated a TEEL-3 value that is consistent with Rev. 29A. The Rev. 29A TEEL-2 basis, a rat oral TDLo, was not found during the current review and was instead derived from the TEEL-3. The Rev. 29A and current methodology are consistent, with differences due to the change in TEEL-2.
