The chemical compositions of PM2.5 including OC, EC, water-soluble ions, elements, and organic components such as polycyclic aromatic hydrocarbons (PAHs), hopanes, and steranes, emitted by various types of vehicles in tunnels were determined.The results showed that the proportions of different constituents of PM2.5 in the Wuzushan (WZS) tunnel were OM (33.2%), EC (32.1%), elements (18.3%),and water soluble ions (9.2%).
