Summary
People in parts of Georgia and Arizona have been advised to stay indoors due to high levels of fine particle pollution, known as PM2.5. The Environmental Protection Agency (EPA) warns that the air quality is "unhealthy," which can pose health risks, especially to sensitive groups like the elderly and children.
Key Facts
- The advisory to stay inside was issued because of "unhealthy" levels of PM2.5 in Georgia and Arizona.
- PM2.5 refers to tiny particles that are 2.5 micrometers or smaller, which can be inhaled into the lungs and sometimes the bloodstream.
- These particles can come from vehicle emissions, industrial activities, and fires.
- Sensitive groups like older adults, children, and people with health issues are at higher risk for health problems.
- The EPA uses the Air Quality Index (AQI) to monitor pollution and inform the public about air quality.
- The AQI scale ranges from "Good" to "Hazardous," with "Unhealthy" indicating some general public health effects.
- The EPA advises reducing outdoor activities when air quality is poor to minimize health risks.
