This follow-up of the Farant and Gariepy study investigates the relationship between benzo(a)pyrene (B(a)P) and other polycyclic aromatic hydrocarbons (PAHs) found in coal tar pitch volatiles in two types of Soederberg aluminum smelters horizontal and vertical stud. The study confirms the strong relationships between B(a)P and total PAHs, and that B(a)P was a good indicator for other PAHs in this industry. The PAH profiles were consistent within each smelter, but the smelter technology used and the changes in the raw material formulation resulted in significantly different profiles. B(a)P toxic equivalency factors for emitted PAH mixtures were greater in the horizontal stud smelter than in the vertical stud smelter. Overall, this study illustrates the potential usefulness of B(a)P relative abundance ratios to simplify exposure assessment in the workplace and reduce associated costs.
