Title: A proposed procedure for derivation of regulatory values for carcinogenic airborne polycyclic aromatic hydrocarbons (PAHs) based on coal tar pitch (CTP) volatiles.

Abstract

A procedure for estimating upper bound lifetime human cancer risk from air levels of six common carcinogenic polycyclic aromatic hydrocarbons (PAHs), termed APAHs of concern, is proposed. These PAHs are benzo(a)pyrene, benz(a)anthracene, benzo(b)fluoranthene, benzo(k)fluoranthene, indeno(1,2,3-c,d)pyrene, and chrysene. In application, this proposed procedure would regard any given air level obtained for a APAH of concern to originate from a standard mixture of coal tar pitch (CTP). The given air level for the APAHs of concern is then related to a corresponding air level of CTP and thence, to an inhalation unit cancer risk calculated for CTP. Reference values for the procedure are the relative and absolute PAH composition of a CTP standard (SRM-1597) and the inhalation unit cancer risk. Qualitative characterization of the results are a vital part of the procedure especially when more than one APAH of concern{at} is being considered. Toxic equivalency factors (TEFs) may be used as an evaluative tool in characterization of the procedure and outcome. Limitations of this proposed procedure include the uneven database for the reference values and the inability to consider air samples inclusive of another common carcinogenic PAH, dibenz(a,h)anthracene, due to its lack of documentation in CTP and high TEF
