AB: In January 2005 the Special Act on Metropolitan Air Quality Improvement was set into force. In July 2006 the new Mayor of Seoul who pushes the Special Plan for Clean Seoul 2010 as a key project was inaugurated. Many new provisions have been implemented during the past few years. However, reduction of PM10 and control of vehicle emissions become a key word of the present management plans to the general public. This is mainly because high concentration of PM10 is easily recognized without intricate devices and vehicles are a core element of urban life. How much a tight control of vehicle emissions will contribute to the management of PM10 in Seoul has come to an issue along with local emission vs. long-range transport, vehicle emission vs. fugitive dust, mass concentration vs. hazardous substances, and so on. In fact, lots of published and measured data indicate that the contribution of vehicle emission, especially that of primary emission of particulate matter from vehicles, to PM10 (mass concentration) is only limited. In this paper the status of PM10 in Seoul was assessed by comparing its concentration and composition to those of other major cities in the world. Temporal and spatial variations in PM2.5 measured between 2002 and 2005 were analyzed in comparison with those in PM10. Smog and health risk were suggested as an issue for managing PM10 as well as PM10 mass concentration. Control factors for the corresponding issues were discussed.
