Introduction

①	Seoul, as well as the Seoul Metropolitan Area in general, has been faced with fourfold difficulties in controlling ozone in the region: an increase of the average concentration of ozone pollution; expanded possibility of secondary ozone generation caused by climate change in urban areas; the cost of reducing the emission of substances with ozone-generating mechanisms; and an increase of health hazards caused by short-term exposure because of the formation of local high concentrations.

②	The purpose of this study is, under recognition of the limitations in the actual application of countermeasures against high-concentration ozone pollution under the current Clean Air Conservation Act and civil participation thereof, to propose an improved plan for preparing and using the manual of countermeasures against ozone based on scientific management, in consideration of the characteristics of ozone generation, diffusion, and impact.

Key Findings

① The annual average concentration of ozone pollution had slowly increased from 0.011 ppm in 1990 until it began to decrease in 2000. Because of temperature increase, which characterizes climate change in urban areas, however, the average concentration began to increase from 2005, continuing the trend ever since.

② The concentration of 95% and 99% ozone continues to increase, showing an elevation of ozone concentration in Seoul.

③ The southwestern area emitted the largest amount of nitrogen oxide in 2010 (30.4% of the total emission), followed by the northeastern (25.5%), southeastern (24.2%), northwestern (12%), and downtown (8.0%) areas. The southwestern area also accounted for the largest percentage of volatile organic compound emission at 32.0%.

④ Emission sources need to be controlled in consideration of the contributions of each area to the emission of ozone-generating substances.
    ㄱ) The use of organic solvent by households and businesses need to be controlled through the implementation of reinforced education and PR activities on the 
         use and storage of eco-friendly organic solvents targeting citizens and business owners.

Policy Suggestions

① Enactment of “Seoul Special Metropolitan City Ordinance on Ozone Forecast and Alert” (draft)
   ㄱ) Securing of the legal basis for ozone pollution forecast/alert, which is required for a systematic approach to high-concentration ozone while considering health 
        hazards for the citizens

   ㄴ) Promotion of the advancement of the legal system of ozone forecast and alert so as to accomplish integrated management and prevention against health hazards 
       caused by fine dust and ozone in the future

  ② Use of the manual for the ozone pollution episodes in Seoul
   ㄱ) “Preliminary stage” will be added to the existing three stages of ozone alert, which involves the announcement of preliminary countermeasures information.
   ㄴ) Ozone generation in Seoul falls into the category of VOC-limited condition: when adjusting VOCs/NOx concentration in each area to control high-concentration 
        ozone, priority should be given to the reduction and control of the use of organic solvent.
   ㄷ) The use of organic solvent by households and businesses account for a large portion of contribution to the overall emission. Therefore, the use of organic solvent 
        need to be controlled through the implementation of reinforced education and PR activities on the use and storage of eco-friendly organic solvents targeting citizens 
        and business owners.

  ㄹ) Promotion of interests against high-concentration ozone and inducement of civil participation
- Establishment of a two-way information delivery system that incorporates a case report of damages caused by high-concentration ozone episodes and a supplement of  
   action plans for transition into a countermeasure system that integrates preventive measures with post facto measures
-  Establishment of an ozone alert monitoring system to prevent the recurrence of health damage caused by ozone pollution by adopting feedback processes aimed at 
    impact assessment after ozone alert
-  Improvement of information generation and announcement through electronic boards related with the generation and diffusion of high-concentration ozone pollution in 
   each area so as to make them more accessible by citizens of Seoul
