Technical Basis
A review of available sources did not identify exposure limits or acute toxicity data for dibenzo(a,e) pyrene. Reported GHS health hazard statements for this chemical (H318, Category 1), which indicate serious eye irritation but no acute toxicity. As such, the PNOS TLV-TWA was selected as the TEEL-1 basis (Section 3.5.2). TEEL-3 and TEEL-2 values were derived according to Table 3.5.
• PAC-1 = TEEL-1 = PNOS TLV-TWA (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 = PNOS TLV-TWA (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*.
