Thousands in Oregon and Montana advised to stay indoors due to fine particle pollution.
Air quality levels have reached "unhealthy" levels across parts of the two states, prompting health officials to urge residents to limit their outdoor activities. The Environmental Protection Agency (EPA) has issued an AirNow Map warning, indicating that people with pre-existing medical conditions such as heart or lung disease should avoid prolonged exposure to fine particle pollution, also known as PM2.5.
These tiny particles, measuring 2.5 micrometers or less in size, can penetrate deep into the lungs and bloodstream, exacerbating existing health conditions. Even healthy individuals may experience symptoms like coughing, eye irritation, and shortness of breath at elevated levels of particle pollution.
The source of the PM2.5 is currently unknown, but potential contributors include smoke from wildfires, vehicle emissions, industrial plant releases, or construction dust. Residents in affected areas are advised to use indoor air purifiers or filters to maintain clean air indoors and avoid burning candles, wood-burning stoves, or open fires until the air quality improves.
To mitigate health risks, the EPA recommends reducing outdoor activities for everyone except those with pre-existing medical conditions. For vulnerable groups, this means avoiding long or intense outdoor activities altogether.
