Technical Basis
A review of available sources was unable to identify exposure limits for this chemical, but toxicity data was available. A rat oral LD50 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 (Table 3.5.)

TEEL-1 = TEEL-2/11
TEEL-2 = TEEL-3/6
TEEL-3 = Rat oral LD50 (924 mg/kg)

This review generated values that are inconsistent with Rev. 29A. The recommended values that are slightly more conservative. The methodology is the same, rat oral LD50, between the current recommendation and Rev. 29A. The basis dose previously reported in Rev. 29A for TEEL-3 was not found during current research.
