Ozone smog slightly worse for Charlottesville metro area while year-round fine particle pollution improves for fifth straight year, finds 2018 ‘State of the Air’ Report
Daily measure of fine particle pollution keeps metro area among ‘Cleanest in U.S.’ for fourth year in a row, according to American Lung Association’s 19th annual air quality report

The American Lung Association’s 2018 “State of the Air” report found that ozone air pollution in the 1-city, 5-county Charlottesville metro area and throughout much of the Mid-Atlantic worsened when compared with last year’s report, even as fine particle pollution levels continued to show good performance and steady improvement. The “State of the Air” report gives results for three measures of air pollution—days with elevated ozone, and daily and annual values for fine particle pollution.
For the sixth consecutive year, Albemarle County, with the only official monitoring in the metro area, met the current national standard for year-round particle pollution, and had the fifth year in a row showing improvement. As a result of Albemarle County making a significant improvement and posting its best ever value for this pollutant, the Charlottesville metro area’s national rank also improved slightly: According to the 19th annual “State of the Air” report, the metro area ranked 146th worst of 187 across the country, an improvement from its ranking of 143rd worst in last year’s report.
For the daily measure of fine particle pollution in the metro area, not only did Albemarle County continue its six-year streak of equaling or improving upon the previous year’s performance, but did so while earning passing grades. And for the fourth consecutive year, Albemarle County continued to earn an “A” grade with zero days of unhealthful air quality, again placing the metro area on the list of “Cleanest Cities” in the country for this pollutant. The metro area’s rank also improved, from 100th worst last year to 112th worst of 201 metro areas in the current report, with fewer areas nationwide being tied for “Cleanest.”
For ozone, Albemarle County posted slightly worse results than in last year’s report, leaving behind last year’s one-time appearance on the list of “Cleanest Cities” in the country for this pollutant. But the county continued with a passing grade under the current standard for the seventh straight year, posting a “B.” As a result, the metro area’s rank worsened from 166th worst last year to 144th worst of 227 in the current report. This is in keeping with a trend seen in most U.S. cities toward higher ozone pollution levels than in last year’s report.
Compared to the 2017 report, the Charlottesville metro area, even as it continued improvement in year-round particle pollution, saw a slight increase in unhealthy days for ozone. This is in keeping with trends seen across the nation for both higher ozone and lower particle pollution levels than in last year’s report.
“The 2018 ‘State of the Air’ report finds that unhealthful levels of ozone in Charlottesville can still occasionally 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 such as COPD. As long as there are many days with high ozone levels, people with lung diseases such as asthma will continue to need medical attention,” said Kevin Stewart, Director of Environmental Health, American Lung Association of the Mid-Atlantic. “Across the nation, the report found continued improvement in air quality, but still, more than four in 10 Americans – 133.9 million – live in counties that have unhealthful levels of either ozone or particle pollution, where their health is at risk.”
The trends in this year’s report, which covers data collected by states, cities, counties, tribes and federal agencies in 2014-2016, confirm the ongoing challenges to reduce each pollutant in the changing political and outdoor climate.
“We can and should do more to save lives,” Stewart said. “The American Lung Association in Virginia calls on our members of Congress to defend the Clean Air Act, currently under threat from those who want to weaken this effective public health law. We also call on the U.S. Environmental Protection Agency to implement and enforce the law instead of trying to roll back major safeguards such as the Clean Power Plan and cleaner cars, both steps that help us fight climate change and reduce air pollution.”
For 19 years, “State of the Air” has provided a report card on the two most widespread outdoor air pollutants, ozone pollution, also known as smog, and particle pollution, also called soot. The report analyzes particle pollution in two ways: through average annual particle pollution levels and short-term spikes in particle pollution. Both ozone and particle pollution are dangerous to public health and can increase the risk of premature death and other serious health effects such as lung cancer, asthma attacks, cardiovascular damage, and developmental and reproductive harm.
“Ozone especially harms children, older adults and those with asthma and other lung diseases,” said Stewart. “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 also revealed 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.
Fine Particle Pollution
Nationwide, the best progress in this year’s report came in reducing year-round levels of particle pollution, and Albemarle County’s performance was consistent with that trend.
“Particle pollution is made of soot, chemicals, and 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 Stewart. “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. While Albemarle County continues to be found among the nation’s cleanest for this measure, in other areas of the country, many of the daily spikes in fine particle pollution were directly linked to weather patterns such as drought or to events such as wildfires, which are likely to increase because of climate change. In some localities, high emissions from wood-burning devices have also been a factor.
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.

The American Lung Association is the leading organization working to save lives by improving lung health and preventing lung disease, through research, education and advocacy. The work of the American Lung Association is focused on four strategic imperatives: to defeat lung cancer; to improve the air we breathe; to reduce the burden of lung disease on individuals and their families; and to eliminate tobacco use and tobacco-related diseases.
