Oregon Air Quality Plummets to Very Unhealthy Levels

Thousands of residents across central Oregon were advised to reduce outdoor activity as air quality reached "very unhealthy" levels early Tuesday. The Environmental Protection Agency's AirNow map indicated a significant area of polluted air over the region, attributed to smoke from multiple prescribed burns. These burns, conducted on the Deschutes National Forest near Sisters and Bend, have led to elevated levels of fine particulate matter (PM2.5).

The "very unhealthy" AQI category poses health risks to everyone, not just sensitive groups. Residents were urged to keep doors and windows closed to minimize indoor smoke. PM2.5 particles are microscopic and can penetrate deep into the lungs, exacerbating existing heart and lung conditions and potentially triggering asthma attacks. Health officials recommend moving outdoor activities indoors, avoiding strenuous exercise, and using air purifiers.

While prescribed burns aim to reduce future wildfire risk, temporary smoke accumulation, especially overnight and early morning, is a common side effect. Officials noted that smoke impacts are expected to improve as burns cease and weather patterns shift. Residents are encouraged to monitor air quality forecasts for real-time updates, as conditions can change rapidly.
