Technical Basis
A review of available sources was able to identify toxicity data for this chemical. The rat oral LD50 toxicity data was selected as the TEEL-3 basis. TEEL-2 and TEEL-1 values were calculated from this TEEL-3, in accordance with guidelines in the handbook (see Table 3.5.)
TEEL-1 = TEEL-2/11
TEEL-2 = TEEL-3/6
TEEL-3 = Rat oral LD50 (951 mg/kg)
This review generated values that are consistent with Rev. 29A.
