| Abstract |
Air samples were collected at various sites in a primary aluminium smelter over a period of four years. There was an excellent relationship between concentrations of benzo[a]pyrene (B[a]P) and concentrations of total polycyclic aromatic hydrocarbons (PAHs). B[a]P was also a good indicator for individual PAHs in coal tar pitch volatiles. B[a]P relative abundance ratios (PAH/B[a]P), derived on the basis of this relationship, showed remarkable stability as long as electrolytic process conditions were not changed. In the absence of any such changes, these values could allow retrospective estimates to be made of the concentration of any of the 18 PAHs selected or total PAHs based solely on the concentration of B[a]P measured at a given site. When combined with B[a]P relative potency factors, these values yield B[a]P toxic equivalent concentrations for any sites where B[a]P levels are known. This parameter provides a viable alternative to all other means of assessing exposure to a complex mix such as PAHs.
