Technical Basis
A review of limited sources did not find exposure limits but did identify rat 4-hr LC50 toxicity data. This dose was selected as the TEEL-3 basis. The basis was scaled to a 60-minute equivalent using the ten Berge equation (Section 3.3.4). TEEL-2 and TEEL-1 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat 4-hr LC50 (>663000 ppm)
This review generated TEEL values that were consistent with those in Rev. 29A.
