Thousands across Alaska, Pennsylvania, and Alabama forced to stay indoors due to hazardous air quality.
The Environmental Protection Agency (EPA) has issued an "unhealthy" air quality alert for multiple communities in these states, warning residents to minimize their time outdoors until the conditions improve. Fine particle pollution, or PM2.5, levels have reached unhealthy levels in Fairbanks, Alaska; Clairton, Glassport, Lincoln, Liberty, and Port Vue in Pennsylvania's Liberty/Clairton area; and parts of Alabama, including Decatur, Cullman, and along Interstate 65.
Residents with pre-existing heart or lung conditions, such as asthma, are advised to take extra precautions. They should keep quick-relief medication on hand and be aware of symptoms like shortness of breath, heart palpitations, or chest tightness, which could indicate a more serious health issue.
The tiny particles in question can become lodged deep in the lungs and bloodstream, exacerbating existing conditions or triggering new ones. PM2.5 pollution can come from various sources, including vehicle emissions, power plants, unpaved roads, construction sites, and smoke.
To communicate air quality levels across the US, the EPA uses a standardized scale called the Air Quality Index (AQI). The AQI assigns a color-coded category to each level of pollution, with green indicating healthy conditions, yellow signaling moderate risks for sensitive individuals, orange warning of unhealthy conditions for vulnerable groups, red signifying unhealthy air for everyone, purple indicating very unhealthy conditions, and maroon indicating hazardous levels that warrant emergency warnings.
In light of these advisories, it is essential for residents to stay informed about air quality conditions in their area and take necessary precautions to minimize exposure.
