%X Vehicular emissions are among major sources of ambient volatile organic compounds (VOCs) in urban areas. To understand the emission of urban vehicles in a real road traffic situation, the Pearl River tunnel in Guangzhou city was selected, and a tunnel experiment for vehicle VOCs emission characteristics and emission factors were performed. The average VOCs emission factor was (0.52±0.07)g?km-1?veh-1. Alkanes, alkenes (with alkynes), and aromatics account for 39.7%, 35.3% and 25.0% in vehicular VOCs emissions. The emission factors for light duty vehicle, heavy duty vehicle and motorcycle were (0.32±0.14), (0.26±0.33), and (1.16±0.26) g?km-1?veh-1 respectively. The Top 3 VOCs species with the highest emission factors were ethene, isopentane and toluene, their emission factors were (52.9±7.4), (41.5±7.0) and (31.7±5.5)mg?km-1?veh-1. The emission factors found from this tunnel experiment agree well with results obtained by dynamometer experiments.
