Technical Basis
A review of available sources identified a PEL-TWA and numerous toxicity data as bases for TEEL development. Data sources were selected according to the hierarchy listed in Table 3.1. Toxicity data were selected according to type of exposure, species, and route based on the hierarchies stated in Sections 3.3.1, 3.3.2, and evaluated using factors in Tables 3.2, 3.3, and 3.4. TEEL-2 values were calculated according to Table 3.5. The PEL-TWA was selected as the TEEL-1 basis.
• TEEL-1 = PEL-TWA (0.2 mg/m3) x 3
• TEEL-2 = TEEL-3/6
• TEEL-3 = Mouse Intraperitoneal LD¬50 (320 mg/kg)
This review generated TEEL values that are consistent with those in Rev. 29A.
