Smoke from Canadian wildfires has been causing air quality problems across several regions in the U.S. This issue is particularly severe in the Northeast and Upper Midwest, where air quality alerts remain in place. Recent statistics reveal that nearly 4,000 wildfires have been recorded in Canada this year, marking one of the worst wildfire seasons on record.
In Michigan, statewide air quality advisories were issued, while Minnesota shows some improvement. However, Wisconsin, New York, Vermont, and Maine are still experiencing smoke issues. The impact of wildfire smoke on health is an emerging concern, especially as climate change contributes to more frequent and intense fires.
Dr. May-Lin Wilgus, a pulmonologist at UCLA, compares inhaling wildfire smoke to smoking several cigarettes a day. The Air Quality Index (AQI) is used to measure air quality, with low numbers indicating cleaner air. However, areas like Detroit have recorded AQI levels well above the acceptable range, leading to increased emergency room visits for respiratory issues. For example, visits for asthma surged by nearly 20% during the Canadian wildfires last year.
Wildfire smoke isn’t just a short-term health hazard. Studies show it can worsen existing conditions and may even increase long-term health risks, including cardiovascular issues and neurological problems like dementia. Tarik Benmarhnia, a climate and health scientist, points out that while air quality in the U.S. has improved over the last two decades, the rise in wildfires is reversing those gains.
According to Lisa Miller, a wildfire smoke expert, the ash from wildfires is more toxic than other air pollution because it often contains harmful burned materials, including household items. This makes the smoke a “toxic soup,” with potential health impacts that are especially dangerous for frail populations like children, the elderly, and pregnant individuals.
For those at higher risk, including first responders and firefighters, repeated smoke exposure is linked to increased health problems. Pregnant people are urged to be particularly cautious, as studies show potential links between smoke exposure and preterm birth or low birth weight.
Protecting yourself from wildfire smoke is crucial. If you can smell smoke, try to limit your exposure. Ideally, stay indoors with windows closed and minimize physical activity. Using an air filter can also help. If you need to go outside, wearing an N95 mask can offer some protection against harmful particles.
As climate change continues to influence the severity of wildfires, addressing the air quality issues related to smoke will remain a critical public health concern.
