Technical Basis
Toxicity data is limited for pentadecafluorooctanoic acid. 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. From RTECs, a rat intraperitoneal LD50 is the most preferable based on source credibility, conservatism, and species/route priority and was selected as the TEEL-3 basis. Independent data is not available for TEEL-2 or TEEL-1; these are derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat intraperitoneal LD50 (189 mg/kg)
This review generated TEEL values that are consistent with Rev. 29A.
