Technical Basis
A review of available sources did not identify exposure limits and acute toxicity found reported no deaths (rat oral and dermal LD50). This chemical is a mixture of undefined ratios. Considering this, the PNOS TLV-TWA was selected as the TEEL-1 basis (PNOS, Section 3.5.2). TEEL-3 and TEEL-2 values were derived according to Table 3.5.
• PAC-1 = TEEL-1 = TLV-TWA (PNOS, 10mg/m3) x 3
• PAC-2 = TEEL-2 = TEEL-1 x 11
• PAC-3 = TEEL-3 = TEEL-2 x 6
This review generated PAC values consistent with Rev. 29A*
• PAC-1 = TEEL-1 = TLV-TWA (PNOS, 10mg/m3) x 3
• PAC-2 = TEEL-2 = TEEL-1 x 11
• PAC-3 = TEEL-3 = TEEL-2 x 6
This review generated PAC values consistent with Rev. 29A*
