2024 showed a notable decline in higher risk to health ratings from wildfire smoke in our region, but every year typically brings at least some poor air quality days as a result of smoke from wildfires.
How is wildfire smoke potentially harmful?
Wildfire smoke is a complex mixture of many gases and particles, but it’s fine particulate matter that poses the main health risk. These particles measure less than 2.5 micron meters (µm) in diameter – so small they can’t be seen without a microscope. A single strand of human hair is at least 20 times larger, averaging 50-70 µm in diameter.
It’s these tiny particles that can get into your eyes, respiratory system and bloodstream (source: MyHealth Alberta).
Assessing your personal health risk using the AQHI
Even so, wildfire smoke affects everyone differently. This is why the Air Quality Health Index (AQHI) is designed to help you decide whether you need to take measures, using your own situation and symptoms as a guide.
MyHealth Alberta advises if you don’t have any specific health concerns, you may simply experience burning eyes, a runny nose, or coughing.
But if you already have a heart or lung health concern, elevated levels of PM2.5 may make it worse.
You are also more at risk if you are pregnant, a senior, or involved in outdoor work or strenuous exercise. Children are more at risk because their respiratory systems are still developing, they breathe in more air and are likely to be more active (source: MyHealth Alberta).
If you live near Bruderheim, Elk Island, Fort Saskatchewan, Gibbons, Lamont or Redwater, you can check your hourly AQHI right on our homepage at heartlandairmonitoring.org.
The following scale can help you determine your risk level and activities accordingly.
