How do I use the Air Quality Index for Health (AQIH)?

Step 1: Read ‘What are the short-term effects of air pollution?’  to see if you or your child is likely to be at risk from air pollution. Your doctor may also be able to advise you.

Step 2: Figure out which Air monitoring station is nearest to you using the map, or which one best represents air quality where you are. Check the AQIH at that station if you think you are at risk, and are planning strenuous outdoor activity.

Step 3: Read the health advice messages for the current AQIH for your region.


The AQIH health advice messages are messages to help you and your family better manage your health. The table below gives health messages for individuals who are sensitive to air pollution (at risk) and for‌ the general population.

If you or child has heart or lung problems you are at greater risk of symptoms from air pollution. You need to follow your doctor's usual advice about exercising and managing your condition. If you are very sensitive, you may have health effects even on days when the air quality is good. Anyone experiencing symptoms should follow the guidance provided in the section on 'What can I do when there are increased levels of air pollution?'.
