Traditionally

• Trends in the ambient levels of key air
  pollutants can be gauged through appropriate and
  systemic monitoring.
• In Thailand, the air quality monitoring system is
  well developed. The Pollution Control Department
  (PCD) has taken the lead in monitoring of key air
  pollutants, establishing ambient standards, and
  recommending policy measures to reduce air
  pollution in critical areas.

Policy on air quality management

• To mitigate air pollution problems in
  non-attainment areas
• To maintain air quality in attainment areas not
  to exceed the national ambient air quality
  standards

Summary Conclusion

• Air quality assessment includes continually
  improvement of emissions, ambient data, and air
  quality modeling to enhance the design,
  implementation and evaluation of air quality
  management programs and related control
  strategies
• The assessment must show timely and meaningful
  pollutant trends and impacts, providing the
  public with clear and transparent information
  that can be effectively used to help them better
  understand the air quality in their area, how it
  can affect their health, and how changes in their
  activities can reduce emissions and improve air
  quality.
