10Conclusion

• Urban developments have been continuing ceaselessly

• Korean government has been undertaking efforts to improve air quality

• There have not been any significant positive effects

• Because the focus of policies has been on controlling the total amount of pollutants

• Needs for urban development strategies with long-term and wider area considerations.
