Air Quality Alerts Issued Across Western U.S. Due to Wildfire Smoke
Air quality alerts have been issued across several western U.S. states, including Oregon, Washington, Idaho, Montana, Colorado, and California, as wildfire smoke and high ozone levels create hazardous breathing conditions. Data from the Environmental Protection Agency's AirNow platform shows widespread 'unhealthy' air quality, with some areas in Oregon reaching the 'Hazardous' category on the Air Quality Index (AQI). Residents are advised to stay indoors, limit outdoor activities, and take precautions, especially if they have respiratory or heart conditions. The primary health threat comes from fine particulate matter (PM2.5), which can penetrate deep into lung tissue.
