Children and teens with asthma are at increased risk during periods of poor air quality, especially during wildfire smoke events. It is unclear how short-term spikes versus sustained exposure to pollutants like PM₂.₅ and NO₂ affect asthma risk in Central Calgary, making it difficult for families to protect vulnerable youth.

I analyzed real-time, government-monitored air quality data from OpenAQ for Central Calgary. I compared two periods: pre-wildfire (Dec 15–17, 2025) and during the wildfire (Dec 18–19, 2025). I examined PM₂.₅, NO₂, and O₃ levels, focusing on peak timing, intensity, and duration, to identify patterns of short-term versus sustained exposure and their potential impact on asthma risk.

I studied how PM₂.₅, NO₂, and O₃ affect asthma in youth and reviewed examples like the 1996 Atlanta Olympics, where reduced pollution led to fewer asthma-related hospital visits.

Air quality data from OpenAQ showed pre-fire short spikes in PM₂.₅ and NO₂ that returned to baseline, while wildfire days had sustained elevated levels. The data highlights increased concentration and longer exposure during the fire.

Wildfire smoke increased both the intensity and duration of PM₂.₅ and NO₂ exposure, raising asthma risk in youth. Sustained exposure poses greater respiratory risk than brief traffic-related pollution spikes
