Technical Basis
A review of available sources identified acute toxicity data (LD50) for several species and routes. In addition, analysts evaluated exposure limits (OEL-TWAs) for soluble aluminum salts (CASRN: 7429-90-5) 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 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 species toxicity data, a rat oral LD50, was selected as TEEL-3 basis. TEEL-2 value was derived according to Table 3.5. The reported OEL-TWA for aluminum sulfate (Finland, as Al), was selected as the TEEL-1 basis and a compound adjustment factor was applied (Section 3.2.2).
• PAC-1 = TEEL-1 = MW-adjusted OEL-TWA (as Al, 1 mg/m3) x 3
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = Rat oral LD50 (1930 mg/kg)
This review generated PAC -3 and PAC-2 values consistent with Rev. 29A, and an inconsistent PAC-1 value. The Rev. 29A and current TEEL-3 and TEEL-2 source, and methodology, are consistent. The Rev. 29A TEEL-1 basis was a weight adjusted, soluble PEL-TWA value that was invalidated. The current TEEL-1 is a weight adjusted OEL-TWA for aluminum sulfate (as Al).
