Millions of residents across parts of Florida, including Tallahassee and the surrounding areas, have been urged to stay indoors as levels of fine particle pollution (PM2.5) have reached unhealthy levels, according to the Environmental Protection Agency (EPA) and its AirNow Map. The EPA advises that when the air quality reaches an unhealthy level, everyone in the affected area should take steps to reduce their exposure, especially those in sensitive groups like the elderly, children, and those with existing heart and lung conditions.

Why it matters

Poor air quality can trigger symptoms like coughing, eye/nose/throat irritation, shortness of breath, and chest tightness. It can also worsen existing heart and lung conditions, potentially resulting in hospitalization. This advisory highlights the importance of monitoring and responding to air pollution levels to protect public health.

The details

The EPA hasn't confirmed the exact cause of the unhealthy air across Florida, but PM2.5 can come from sources like dust, smoke, and emissions. PM2.5 is considered one of the most dangerous forms of air pollution because the tiny particles can be inhaled deep into the lungs and bloodstream, even during physical outdoor activity.
