Air Quality Health Index

The Air Quality Health Index or "AQHI" is a public information tool.  Using the AQHI can help you to better protect yourself from the negative effects of air pollution. You can do this by:

  • limiting short-term exposure to air pollution, and
  • adjusting your activity when air pollution levels are high. 

You can also help your neighbours breathe easier by avoiding activities that make air quality worse (e.g., backyard burning).

The Air Quality Health Index measures air quality on a scale from 1 to 10.  The higher the number, the greater the health risk associated with breathing the air.  When the amount of air polution is very high, the number will be reported as 10 .   

Information used to calculate the Air Quality Health Index comes from three monitoring stations across the province: 



 St. Peter’s Bay

These stations are operated by the PEI Department of Communities, Land and Environment.  The Air Quality Health Index is provided in partnernship with PEI Department of Health and Wellness, Health Canada, and the PEI Lung Association.
