The present frame of national air pollution monitoring networks was established between the end of the 1980s and the beginning of the 1990s. Background monitoring was initiated in the middle of the 1990s in response to increasing public concern about the long-range transport of air pollutants. Apart from the national monitoring, both routine and intensive measurements of fine particles have been made for research purposes since the middle of the 1990s at several background sites. However, air pollution monitoring in urban areas for other purposes was relatively scarce as national monitoring has been concentrated in these areas. Although ozone pollution has become a significant issue in major metropolitan areas every summer, only a little information on ozone precursors is available. During the past few years, the number of national monitoring stations has greatly increased. The government has a plan to gradually expand monitoring items as well as stations. It is anticipated that highly detailed information on both photochemical reactants and products will be available within the next several years. More emphasis will be placed on toxic substances based on risk assessment in monitoring for both research and policy making. 한국대기환경학회 A Commentary on Air Pollution Monitoring Programs in Korea Article 2 Journal of Korean Society for Atmospheric Environment, v.18, no.1, pp.21 - 28 Journal of Korean Society for Atmospheric Environment 18 1 21 28 ART000897473 Air quality issues Monitoring network Long range transport Fine particles Ozone pollution Toxic substance
