Air Pollution Index & You [Image] Our air pollution problems are related mainly to long-term health effects caused by persistently high levels of tiny particles that can penetrate deep into our lungs. However, our air pollution levels sometimes can become so high that they may have more immediate impacts for those with existing heart or respiratory illnesses. In addition to continuing our efforts to combat air pollution, we also provide you with an hourly Air Pollution Index to let you know about the quality of the air you are breathing. What is the Air pollution index? How is the API Calculated and Reported? What does the API tell us? Which API should I refer to? What about the roadside APIs? What action should I take?
