Technical Basis
A review of available sources identified mouse acute toxicity data (LD50) for several routes. In addition, analysts evaluated available exposure limits for soluble iron salts (TWAs). 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 preferred route, a mouse intraperitoneal LD50, was selected as the TEEL-3 basis. The TEEL-2 value was derived according to Table 3.5. The TLV-TWA for soluble iron salts were selected as the TEEL-1 basis and a compound adjustment factor was applied (Section 3.2.2).
• PAC-1 = TEEL-1 = MW-adjusted TLV-TWA (iron soluble salts, CASRN: 7439-89-6; 1 mg/m³) x 3
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = Mouse intraperitoneal LD50 (601 mg/kg)
This review generated PAC values consistent with Rev. 29A.
