Washington-Baltimore-Arlington Metro Area Continues to Rank Among Worst 25 in Nation for Ozone Smog, Harford County MD Worst in Metro, with “F” Grade.

Year-round Particle Pollution Worsens, Finds 2021 ‘State of the Air’ Report; Days with High Ozone or Particles Remain a Threat

This year’s “State of the Air” report from the American Lung Association finds that the Washington-Baltimore-Arlington, DC-MD-VA-WV-PA metro area, covering the District of Columbia and 40 other counties and independent cities, and home to nearly ten million people, ranked as the 22nd most polluted for days with high levels of ozone smog, among the worst in the country. In contrast, for the 16th year in a row, the metro area equaled or improved upon the previous year’s worst county’s number of unhealthy days on average for daily spikes of fine particle pollution. But breaking a 13-year streak of consecutive years of improvement, the metro area’s worst county’s year-round level of particle pollution worsened. See the full report, based on the three years of data from 2017 through 2019, at Lung.org/sota . 

The worst grades in the metro area for the daily measure of particle pollution (a “B” in five jurisdictions) and ozone smog (an “F” in six jurisdictions) remain of concern even though the latter showed improvement over last year’s results. “Clearly, both show room for improvement and more must be done to protect the health of people at risk,” said American Lung Association Director of Environmental Health Kevin Stewart. “There are dozens of days when air pollution levels are high enough to harm health and trigger asthma attacks, heart attacks and stroke, placing children, older adults, and people living with chronic lung and heart disease at particular risk. Ozone and particle pollution are the nation’s most harmful and widespread air pollutants, and both can be deadly. In addition, more exposure to particle pollution is linked to worse health outcomes from COVID-19, including more deaths.” 

“The American Lung Association’s 2021 ‘State of the Air’ report shows that despite some nationwide progress on cleaning up air pollution, more than 40% of Americans live with unhealthy ozone or particle pollution,” said Stewart. “People of color—comprising nearly half of the metro area’s population—are significantly more likely to breathe polluted air than white people. As the nation works to address climate change and continue reducing air pollution, we must prioritize the health of disproportionately burdened communities.” 

Ozone Pollution in the Washington-Baltimore-Arlington, Metro Area - Compared to the 2020 report, the Washington metro area experienced significantly fewer unhealthy days of high ozone, but still more than the area’s best-ever performance in 2013-2015. Harford County, MD was the county in the metro area with the worst performance for ozone in this year’s report, reporting a weighted average of 9.3 days (an “F” grade) with unhealthy levels of this pollutant, displacing last year’s worst county, Baltimore County, MD, which had posted an average of 14.2 days (also an “F”) high in ozone. The area’s best result was 6.7 days (still an “F”) in the 2017 report. The area’s ranking improved to 22nd most polluted from 20th worst in the country last year, again placing the metro area among the nation’s 25 worst cities for this pollutant.   

“Ozone pollution can harm even healthy people, but is particularly dangerous for children, older adults and people with lung diseases such as COPD or asthma,” said Stewart. “Breathing ozone-polluted air can trigger asthma attacks in both adults and children with asthma, which can land them in the doctor’s office or the emergency room. Ozone can even shorten people’s lives.”   

Particle Pollution in the Washington-Baltimore-Arlington Metro Area - “State of the Air” 2021 found that year-round particle pollution levels in the Washington metro area, after improving for 13 straight years, hit a worse annual average, but still met the air quality standard for this pollutant. The District was the most polluted “county” for the metro area for year-round particle pollution, posting an average level of 9.5 µg/m3 (micrograms per cubic meter) for 2017-2019, and displacing Howard County, MD which had recorded a level of 9.1 µg/m3 for 2016-2018, the metro area’s best performance ever. The Washington metro area’s ranking worsened to 39th most polluted in the country from 49th worst in last year’s report. 

The report also tracked short-term spikes in particle pollution, which can be extremely dangerous and even lethal. For the 16th year in a row the metro area equaled or improved upon the previous year’s number of unhealthy days on average for particle pollution. In 2017-2019, it matched the past three years’ unchanged lowest level ever, with Baltimore City, MD and Berkeley County, WV, each recording the same worst result in this year’s report, a weighted average of 0.7 days (a “B” grade). Due to improvements in other areas of the country, the area’s ranking worsened to 57th most polluted from 64th worst in last year’s report. 

““Particle pollution can lodge deep in the lungs and can even enter the bloodstream. It can trigger asthma attacks, heart attacks and strokes and cause lung cancer,” said Stewart. “Particle pollution comes from industry, coal-fired power plants, construction, agriculture, vehicles, wildfires and wood-burning devices.”   

This year’s report found that nationwide, more than four in 10 people (135 million) lived with polluted air, placing their health and lives at risk. In the Washington-Baltimore-Arlington Metro Area, air pollution placed the health of the nearly ten million residents at risk, including those who are more vulnerable to the effects of air pollution, such as older adults, children and people with a lung disease. The report also shows that people of color were 61% more likely to live in a county with unhealthy air than white people, and three times more likely to live in a county that failed all three air quality grades. The report also finds that climate change made air quality worse and harder to clean up. 

The Lung Association’s annual air quality “report card” tracks and grades Americans’ exposure to unhealthful levels of particle pollution (also known as soot) and ozone (smog) over a three-year period—this year’s report covers 2017-2019. The report analyzes particle pollution in two ways: average annual levels and short-term spikes. Both ozone and particle pollution can cause premature death and other serious health effects such as asthma attacks and cardiovascular damage, and are linked to developmental and reproductive harm. Particle pollution can also cause lung cancer.
