Technical Basis
A review of limited data sources was unable to identify exposure limits or toxicity data appropriate for TEEL development. Instead, an HHR=2 was selected as the basis for a TEEL-3 estimate due to its classification as a hazardous substance in reputable chemical safety data sheets. TEEL-2 and TEEL-1 values were derived from this TEEL-3, according to guidance in the Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Estimated from HHR=2 (Rat Oral LD50 4000 mg/kg)
This review generated TEEL values inconsistent with those published in Rev. 29A.
