"Medium" API is 26 - 50. No response action required.
"High" API is 51 - 100. No immediate response action is suggested. Long-term effects may, however, be observed
if exposed at such level persistently for months or years.
"Very High" API is 101 - 200. Persons with existing heart or respiratory illnesses, childrens and the elderly are
advised to reduce physical exertion and outdoor activities. They are also advised to seek advice from a medical
doctor before participating in sport activities and take more breaks during the activities.
"Severe" API higher than 200. Persons with existing heart or respiratory illnesses, childrens and the elderly are
advised to avoid physical exertion and outdoor activities. The general public is advised to reduce physical exertion
