Despite continued improvement in air quality, residents' health remains at risk from unhealthy air, according to American Lung Association's 19th annual air quality report
ATLANTA – The American Lung Asociation's 2018 "State of the Air" report found Atlanta ranked as the 23rd most polluted city for ozone in the nation. Compared to the 2017 report, Atlanta has seen an increase in the number of unhealthy days of high ozone. This is in keeping with a trend seen across the nation of higher ozone pollution levels.

Atlanta is tied for 22nd most polluted city for year-round particles even though its levels are lower than last year's report. Atlanta is also tied for the 65th most polluted city for short-term particle pollution.



"The 2018 'State of the Air' report finds that unhealthful levels of smog, year-round particles and short-term particle pollution in Atlanta put our citizens at risk for premature death and other serious health effects such as asthma attacks and greater difficulty breathing for those living with a lung disease like COPD," said June Deen, Senior Vice President of Public Policy and Health Promotions of the American Lung Association in Georgia.

Ozone Pollution in Atlanta
Compared to the 2017 report, Atlanta experienced more unhealthy days of high ozone in this year's report. In fact, Fulton County, the most polluted county in the metro area, had a worse weighted average with 10.2 days of unhealthy levels of ozone in 2014-2016.

"Ozone especially harms children, older adults and those with asthma and other lung diseases," said Deen. "When older adults or children with asthma breathe ozone-polluted air, too often they end up in the doctor's office, the hospital or the emergency room. Ozone can even shorten life itself."

This report documents how warmer temperatures brought by climate change make ozone more likely to form and harder to clean up. This year's report showed that ozone levels increased in most cities nationwide, in large part due to warmer temperatures in 2016, the second hottest year on record in the U.S. Over the past decades, ozone pollution has decreased nationwide because the nation has cleaned up major sources of the emissions that create ozone, especially coal-fired power plants and vehicles.
Particle Pollution in Atlanta
The 2018 report also found year-round particle pollution levels decreased slightly than the 2017 report and the metro area still meets the national standard. Nationwide, the best progress in this year's report came in reducing year-round levels of particle pollution.

"Particle pollution is made of soot or tiny particles that come from coal-fired power plants, diesel emissions, wildfires and wood-burning devices. These particles are so small that they can lodge deep in the lungs and trigger asthma attacks, heart attacks, and strokes, and can even be lethal," said Deen. "Year-round particle pollution levels have dropped thanks to the cleanup of coal-fired power plants and the retirement of old, dirty diesel engines."

"State of the Air" 2018 also tracked short-term spikes in particle pollution, as these can be extremely dangerous and even lethal. The report found that the metro area had more days when short-term particle pollution reached unhealthy levels in 2014-2016.

While the report examined data from 2014-2016, this 19th annual report provides online information on air pollution trends back to the first report covering 1996-1998.
