Technical Basis
A review of this chemical identified a rat oral LD50 that was selected as the TEEL-3 basis and evaluated using factors in Tables 3.2, 3.3, and 3.4. TEEL-2 and TEEL-1 values were derived according to Table 3.5.
• PAC-1 = TEEL-1 = TEEL-2/11
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = Rat oral LD50 (20900 µg/kg)
This review generated PAC values inconsistent with Rev. 29A. The Rev. 29A TEEL-3 was a weight adjusted 1990 cyanide IDLH (CASRN: 57-12-5). The current TEEL-3 basis is acute toxicity for potassium silver cyanide. The Rev. 29A and current TEEL-2 and TEEL-1 use the same methodology, with differences due to the change in TEEL-3.
