Technical Basis
Toxicity data is investigated for ammonium sulfate. From SAX, a rat oral LD50 is selected for TEEL-3 development (most preferable based on Sections 3.3.1, 3.3.2). Independent data is not available for TEEL-2 or TEEL-1; these are derived from the fill gap adjustment factors (Table 3.5).
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Estimated from rat oral LD50 (3000 mg/kg)
This review generated TEEL values that are more conservative than Rev. 29A. The same methodology was used in both versions, considering source credibility and conservatism, the SAX data takes priority.
