The Environmental Protection Agency's AirNow map is showing large areas of "unhealthy" air quality in parts of Arizona and Georgia on Saturday, with thousands of residents advised to limit outdoor activities and stay inside due to concerns over elevated ozone and fine particle pollution levels.

Why it matters

Air pollution can pose serious health risks, especially for sensitive groups like children, older adults, and those with certain medical conditions. These warnings underscore the ongoing challenges many communities face in maintaining clean air and the need for continued efforts to address air quality issues.

The details

According to the AirNow map, the Tucson, Arizona area and parts of the San Carlos Reservation are experiencing "unhealthy" ozone and fine particle (PM2.5) pollution as of 7:25 a.m. ET. A separate area of "unhealthy" air quality is also present in Valdosta, Georgia. When air quality reaches this level, the EPA advises sensitive groups to avoid prolonged outdoor activities and the general public to reduce intense outdoor exertion.
