AbstractIn this study, vehicle exhaust particles were collected three locations (the middle, entrance and outside) of the Dapu Road tunnel in downtown Shanghai, and the particle samples were characterized using SEM, XAFS, ICP-MS and Mossbauer spectrometry, and the oxidative damage was assessed by plasmid DNA. Most iron-containing particles are found from vehicle exhaust, and iron oxide is the major species in all samples. Its concentration in the particles inside the tunnel is higher than that the outside particles. The iron particles inside the tunnel have higher proportion of water-soluble fraction in hydrous iron sulfate form or smaller size. ZnCl(2) is the main soluble fraction in zinc-containing particles, while higher percentage of insoluble fraction existed in the particles outside of tunnel. Major species of lead-containing particles are PbSO(4), Pb(3)(PO(4))(2) and PbCO(3). In addition, the soluble fraction of other transition metallic elements as Ti and V is higher in the particles inside the tunnel than that outside the tunnel. The plasmid DNA assay results indicate that the particles from vehicle exhaust have a stronger oxidative damage and inflammation than that from outside of the tunnel.
