THE CONTRIBUTION OF TRAFFIC TO ATMOSPHERIC CONCENTRATIONS OF POLYCYCLIC AROMATIC HYDROCARBONS

This study uses three separate techniques to estimate the concentrations of PAH at both a heavily trafficked city center location and an urban background site. Despite the distance between the two sites exceeding that used in an earlier study, the methods still functioned well, suggesting that these source apportionment techniques may have wide generic applicability. While each estimation method has an associated uncertainty, the narrow range of estimates obtained from different methods supports the overall conclusion that traffic emissions are the most significant source of atmospheric PAH in Birmingham, UK. The contribution of diesel emissions to those of traffic overall is shown to be appreciable. It is clear that reducing traffic emissions of PAH is likely to play an important role in lowering atmospheric concentrations of these compounds. (A)
