Thousands of people in Georgia and Arizona have been warned to stay indoors due to hazardous levels of fine particle pollution, with the Environmental Protection Agency (EPA) deeming it "unhealthy" for those in sensitive groups.
AirNow Map data from the EPA suggests that tiny airborne particles known as PM2.5 are causing health concerns across the region. The particles are created by various sources including vehicle emissions, industrial processes, construction dust, and smoke from wildfires or smokestacks.
As a result of these elevated levels of pollution, experts advise individuals with pre-existing conditions like asthma to limit their outdoor activities altogether. Everyone else is recommended to reduce the intensity or duration of their outdoor activities.
The risks associated with PM2.5 are significant, as they can penetrate deep into the lungs and bloodstream, potentially triggering symptoms ranging from mild irritation to severe respiratory issues. Even healthy individuals may experience temporary health effects.
To mitigate this risk, the EPA uses a color-coded Air Quality Index (AQI) that translates pollution levels into health guidance for the public. The index ranges from green (good air quality), yellow (moderate air quality), orange (unhealthy for sensitive groups), red (unhealthy air quality), purple (very unhealthy air quality), and maroon (hazardous air quality).
The region is currently classified as "red" on this scale, indicating that hazardous levels of pollution pose a significant risk to public health.
