Objectives: The purpose of this study was to provide policy directions for air pollution reduction by analyzing the variation in the characteristics of air contaminants around the Gyeonggi Province area. Methods: The data used in the study was obtained from air quality monitoring stations operated by the Gyeonggi Provincial Government. The target area was the air quality management area of the Gyeonggi Province region. Results: The concentration of PM10 (particles measuring 10 μm or less) in 2009 was 60 μg/m3, which has been reduced by about 2.7% per year after improvement countermeasures were emplaced. The air pollution control policy was especially more effective for coarse particulate matter (CPM, PM10-2.5). The improvement of NO2 pollution was generally very low, especially in cities which had considerable automobile traffic. The concentration of SO2 pollution was rapidly improved in industrial areas, but did not show any difference for multiple and general cities. The predicted concentration of PM10 for 2014 based on the trend over 2001-2009 was 53.4 μg/m3, which fails to meet the target concentration of 40 μg/m3. The predicted concentration of NO2 shows a very low probability of achieving the target concentration of 22 ppb, and thus the current improvement of air quality has proven unsatisfactory. Conclusion: Air pollution control policy should be enforced according to regional pollution characteristics in order to obtain maximum effectiveness in improvement.
