Technical Basis
A review of available sources identified rat and mouse LD50 toxicity data for various routes (oral, intravenous). 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 according to the hierarchies stated in Sections 3.3.1, 3.3.2, and evaluated using factors in Tables 3.2, 3.3, and 3.4. The most preferred data, a rat oral LD50, was selected as the TEEL-3 basis. TEEL-1 and TEEL-2 values were derived according to Table 3.5.
• PAC-1 = TEEL-1 = TEEL-2/11
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = Rat oral LD50 (2650 mg/kg)
This review generated PAC values that are inconsistent with Rev. 29A. The Rev. 29A TEEL bases were the MW-adjusted ERPG-1,2, and 3 values for formic acid (CASRN: 64-18-6), while the current TEEL-3 basis is a chemical-specific rat oral LD50, and the TEEL-2 and TEEL-1 are derived according to Table 3.5.
