Technical Basis
A review of available sources identified the following: rat LC50 and LD50 acute toxicity data. Both were evaluated and returned identical TEEL values. However, the rat LD50 was chosen as the TEEL-3 basis, due to the source being clearly referenced, while the source of the LC50 is unclear. 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 (4850 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 (4850 mg/kg)
This review generated TEEL values consistent with those in Rev. 29A.
