New Report: Little Rock’s Air Quality Worsens; Is Worst in the Southeast for Year-Round Particle Pollution

According to the American Lung Association’s “State of the Air” report, released today, air quality in the Little Rock metro area has worsened. Residents are being exposed to more unhealthy ozone smog and particle pollution. In fact, Little Rock is tied for worst metro area in the Southeast for year-round particle pollution. Additionally, the report found that nearly half of the U.S. population live in areas with unhealthy levels of air pollution. Extreme heat and wildfires contributed to worsening air quality in much of the country.

The Lung Association’s 26th annual “State of the Air” report grades exposure to unhealthy levels of ozone pollution, also known as “smog,” and particle pollution, also known as “soot,” over a three-year period (2021-2023). Findings for the Little Rock metro area include:

• Ground-level Ozone Pollution:
  • Number of Unhealthy Days per Year: 2 days (1.3 days in 2024 report)
  • Grade: C (C in 2024 report)
  • National Ranking: 100th worst out of 228 (71st worst in 2024 report)
• Short-Term Spikes in Particle Pollution:
  • Number of Unhealthy Days Per Year: 0 days (0.3 days in 2024 report)
  • Grade: A (B in 2024 report)
  • National Ranking: 204th out of 223 (124th worst in 2024 report)
• Year-Round Average Level of Particle Pollution:
  • Grade: Failing grade, pollution levels above the federal standard (passing grade in 2024 report)
  • National Ranking: 26th worst out of 204 – tied for worst in Southeast (78th worst in 2024 report)

Ozone and particle pollution are widespread and can impact anyone’s health. Both pollutants can cause premature death and other serious health effects such as asthma attacks, heart attacks and strokes, preterm births and impaired cognitive functioning later in life. Particle pollution can also cause lung cancer.

“Unfortunately, too many people in the Little Rock metro area are living with unhealthy levels of particle pollution and ozone pollution. This air pollution is a threat to human health at every stage of life—increasing the risk of premature birth and low birth weight in babies to causing or worsening lung and heart disease to shortening lives,” said Laura Turner, Arkansas director of advocacy at the Lung Association. “We urge Arkansas policymakers to take action to improve our air quality, including allocating funds to place air quality monitors in the 64 counties without them. We are calling on everyone to support the incredibly important work of the U.S. Environmental Protection Agency (EPA). Without EPA staff and programs, Arkansans won’t know what’s in the air they’re breathing, and efforts to clean up air pollution will be undone.”

In addition to the Little Rock metro area, other notable findings across Arkansas include:

• Ozone smog in the Fayetteville metro area worsened for the third consecutive report, with the grade dropping from “C” to “D.” Since the 2012 report, it remains among the nation's cleanest for daily particle pollution. Year-round particle pollution worsened slightly, but still passes.
• Both ozone smog and daily particle pollution remained unchanged from previous report in the Fort Smith metro area, both results earning “B” grades. Year-round particle pollution worsened, but still passes.

The “State of the Air” report relies on data from air quality monitors managed by state, local and Tribal air pollution control authorities in counties across the U.S. In Arkansas, only 11 out of 75 counties could be graded for at least one measure of air quality. This underscores the need for more monitors and access to air quality data so that people and communities can take measures to safeguard their health. 

On a national level, the “State of the Air” report found that 156 million people in the U.S. (46%) live in an area that received a failing grade for at least one measure of air pollution. 42.5 million people live in areas with failing grades for all three measures. The report also found that a person of color in the U.S. is more than twice as likely as a white individual to live in a community with a failing grade on all three pollution measures. Notably, Hispanic individuals are nearly three times as likely as white individuals to live in a community with three failing grades.

The Lung Association is calling on everyone to support the U.S. Environmental Protection Agency. EPA is essential to protecting people’s health from ozone and particle pollution.
