Technical Basis
Exposure limits were not available for this chemical. A review of available toxicity identified a rat oral LD50 as the most preferable species and route. This value was chosen as the starting point for TEEL-3 development. TEEL-2 and TEEL-1 were derived using the adjustment factors from Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat oral LD50 (2072 mg/kg)
This review generated TEEL values consistent with those published in Rev. 29A.
