Technical Basis
A review of available sources identified the following: a TLV-Ceiling and rat oral LD50 toxicity data. Data sources were selected according to the hierarchy listed in Table 3.1. Toxicity data were evaluated using factors in Tables 3.2, 3.3, and 3.4. The rat oral LD50 was selected as the TEEL-3 basis. The TLV-C was selected for TEEL-2. TEEL-1 values were calculated according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TLV-C
• TEEL-3 = Rat Oral LD50 (273 mg/kg)
This review generated TEEL values consistent with those in Rev. 29A.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TLV-C
• TEEL-3 = Rat Oral LD50 (273 mg/kg)
This review generated TEEL values consistent with those in Rev. 29A.
