Technical Basis
Benz(e)acephenanthrylene is “a component of coal tar pitch”; a review of available sources did not identify exposure limits or acute toxicity data for benz(e)acephenanthrylene. Instead, analysts evaluated exposure limits available for coal tar pitch volatiles (CPTV, CASRN: 65996-93-2, TWAs, IDLH). Data sources were selected according to the hierarchy listed in Table 3.1. The TLV-TWA was selected as the TEEL-1 basis. The original (1990) and revised (1994) IDLH for CPTV were both developed from chronic toxicity data and were therefore determined inappropriate for TEEL development. Instead, TEEL-2 and TEEL-3 values were derived according to Table 3.5.
• TEEL-1 = TLV-TWA (coal tar pitch volatiles, CASRN: 65996-93-2, 0.2 mg/m3) x 3
• TEEL-2 = TEEL-1 x 11
• TEEL-3 = TEEL-2 x 6
This review generated TEEL values inconsistent with Rev. 29A. The Rev. 29A TEEL-1 basis was an OEL-TWA, while the current basis is a TLV-TWA. The Rev. 29A and current TEEL-2 and TEEL-3 use the same methodology, with differences due to the change in TEEL-1.
