Wildfire season typically runs from early April to late October. As wildfire burns through forests and grasslands, it produces dense smoke that can be a major source of toxic air pollutants. This pollution contains fine particles (that are not visible to the human eye) that penetrate deep into our lungs and bloodstream, sometimes leading to serious health effects. Those at greater risk of these effects are:
- small children
- pregnant women
- elderly
- people with lung or heart conditions
- people involved in strenuous outdoor work or sports
