Abstract: The airborne Non-Methane Organic Compounds (NMOCs) were measured during rush hour and non-rush hour at two traffic sites and an industrial site in the largest industrial city in Taiwan. The results showed the major components in their NMOCs profiles were similar among the three sites. Aromatics compounds were the dominant species group (31-61%), and toluene is the major HAPs species. The results of the aging assessment of the air mass implied the NMOCs were contributed by local sources and also indicated that vehicles might be the dominant source of these compounds collected in the area.
