Residents in Georgia are being urged to remain indoors as the area’s air quality has plummeted to dangerous levels as of Friday morning.
The U.S. Environmental Protection Agency (EPA) has reported that pollutants within a 40-mile radius of Albany, Georgia, have escalated to ‘very unhealthy’ levels, marking the agency’s second-highest alert category.
Real-time data indicates a significant surge in PM2.5 levels. These are tiny particles made up of toxic substances or heavy metals small enough to penetrate the lungs, aggravating conditions like asthma, and potentially leading to premature death.
The air quality monitoring site IQAir has documented Albany’s Air Quality Index (AQI) soaring to 239. This figure places it among the worst air quality ratings globally, second only to Cairo, Egypt.
The AQI measures air quality on a scale from 0 to 500. A reading between 0-50 is considered good with minimal risk, while 51-100 is moderate, affecting only sensitive groups. Levels from 101-150 pose increased risks to sensitive individuals, and 151-200 is considered unhealthy for the general population, suggesting outdoor activities should be limited.
When the AQI reaches 200 or higher, as seen in Albany, the air becomes so polluted that health officials warn that prolonged exposure can increase the risk of cancer, strokes, and heart attacks. Residents are advised to limit outdoor activities, refrain from exercising outside, and wear face masks if they must go outdoors.
The skyrocketing PM2.5 levels have been linked to recent wildfire smoke, which exacerbates a condition called stagnant air, where little to no wind and high atmospheric pressure trap pollution near ground level.
The National Weather Service has issued a major fire danger warning throughout most of North and Central Georgia, with winds currently moving south into the area around Albany.

An even larger swath of Southern Georgia was reported by the EPA as falling into the ‘unhealthy’ category Friday morning, stretching roughly 150 miles across the state, from the state’s border with Alabama to Georgia’s Coastal Plain.
IQAir has reported multiple crop fires north of the zone hovering over Georgia, specifically in Adrian, Archery, and Millen, with winds pointed south towards the areas with AQI scores exceeding 150 Friday morning.
To understand the impact of stagnant air on nearby wildfire smoke, it is helpful to look at atmospheric pressure. Pressure is measured in millibars, with normal sea-level pressure being 1,013 millibars.
Anything between 1,015 and 1,020 millibars is considered a high-pressure system, with strong pressure exceeding 1,030 millibars, especially in the winter.
Albany’s air pressure was recorded surpassing 1,022 millibars when the worst AQI scores were seen, causing sinking air from above to warm and compress as it descends.
Stagnant air means the air around you is barely moving, like it’s stuck under a lid, so pollution, fire smoke, car fumes, and other particles can’t blow away or mix higher up in the atmosphere, causing them to build up near the ground where we breathe.
Albany sits at the center of the hazardous zone, and the city has been a hotspot for poor health in the past.
In April 2020, the city became one of the worst places per capita for Covid-19 infections, with the fourth worst infection rate in the US.

The National Weather Service (NWS) has warned that any fires which develop throughout the region on Friday could spread extremely fast due to low humidity and dry vegetation across the state.
NWS officials urged residents against any kind of burning while the conditions remain dangerous, which forecasters project will be until 7pm ET.
At the peak of the air quality alert, pollution readings in Albany showed that PM2.5 levels were over 32 times higher than the World Health Organization recommended safe limits.
As of 10.30am, the EPA has also listed a large area surrounding Hattiesburg, Mississippi as having ‘unhealthy’ levels of PM2.5 filling the air.
In Chattahoochee, Florida, just 80 miles south of Albany, air quality readings have reached the 170s, according to IQAir.
