Technical Basis
A review of available sources identified guinea pig oral LDLo toxicity data. This data was evaluated using factors in Tables 3.2, 3.3, and 3.4. The guinea pig oral LDLo data was selected as the TEEL-3 basis, and the TEEL-1 and TEEL-2 values were calculated according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = guinea pig oral LDLo (600 mg/kg)
This review generated TEEL-3 and TEEL-2 values that are consistent with Rev. 29A. The TEEL-3 basis remains the same as Rev. 29A, however the Finland OEL-TWA value used as the TEEL-1 basis in Rev. 29A was not located in this review.
