Technical Basis
A review of limited sources identified acute toxicity data for mouse intraperitoneal LD50. In addition, analysts evaluated exposure limits for soluble iron salts (Fe, CASRN: 7439-89-6) for TEEL development (Section 3.2.2). 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 mouse intraperitoneal was selected as the TEEL-3 basis. The TEEL-2 was derived according to Table 3.5. The OEL-TWA was evaluated but resulted in a TEEL-1 > TEEL-2; instead, the TEEL-1 was derived according to Table 3.5.
• PAC-1 = TEEL-1 = TEEL-2/11
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = Mouse intraperitoneal LD50 (168 mg/kg)
This review generated PAC values inconsistent with Rev. 29A. The Rev. 29A TEEL-1 basis was MW-adjusted TLV-TWA as iron, from which the TEEL-2 and TEEL-3 were derived. The current TEEL-3 was derived from acute toxicity for ferric sulfate, from which the TEEL-2 and TEEL-1 were derived.
