April 22 (UPI) — More than 152 million people in the United States – about 44%– live in areas that have unhealthy levels of ozone or particle pollution, the American Lung Association said in the 2026 State of the Air report released Wednesday.
The report also noted that 44.6% of U.S. children live in counties that have failing grades for at least one measure of air pollution,while 10% of children live in counties with failing grades in all three measures. These measures include ground-level ozone (smog) and both short-term and year-round particle pollution (soot).
“Infants, children and teens are especially vulnerable to the health harms of breathing pollution,” the report said. “Their lungs are still developing, they breathe more air for their body size than adults and they frequently spend more time outdoors.”
The report showed that trends from last year’s edition continued and often grew worse, including extreme heat in many places that affected ozone levels and wildfires in Canada that affected ozone and particle pollution.
“Clean air is not something we can take for granted,” American Lung Association President Harold Wimmer said in announcing the report, the Washington Post reported. “For decades, people in the U.S. have breathed cleaner air thanks to the Clean Air Act. Unfortunately, that process is now at risk due to extreme heat and wildfires, fueled by climate change, and policy changes that are making the problem worse.”
The Clean Air Act became effective in 1963. This is the 27th edition of the State of the Air report, which was first released in 2000. The report has reflected the act’s successes over the years, but over the past decade, also the challenges of the changing climate, the American Lung Association said.
“Increases in high ozone days and spikes in particle pollution related to extreme heat, drought and wildfires are putting millions of people at risk and adding challenges to the work that states and cities are doing across the nation to clean up air pollution,” the report said.
The authors of the State of the Air report noted that levels of unhealthy air vary widely across the country and that people of color disproportionately live in areas with poor scores. A person of color is 2.42 times as likely as a white person to live in an area with poor scores for all three air pollution measures.
For the seventh year in a row, Bakersfield, Calif., was the metropolitan area with the worst level of year-round particle pollution. Fairbanks, Ala., moved to the worst spot for short-term particle pollution. Los Angeles remained the metropolitan area with the worst ozone pollution. It’s held that spot for 26 years of the report’s 27-year history.
Only one city – Bangor, Maine – had good marks in all three measures.
In county rankings, San Bernardino in California had the highest level of ozone pollution; the five worst counties in the country in this measure were all in California. In short-term particle pollution, Fairbanks North Star Borough in Alaska was ranked as the worst. In long-term particle pollution, Kern County in California held that spot.
Twenty counties throughout the United States had failing grades for all three measures of air pollution: Maricopa in Arizona; Fresno, Imperial, Kern, Kings, Los Angeles, Merced, Riverside, San Bernardino, Stanislaus and Tulare in California; Lake and Marion in Indiana; Wayne County in Michigan; Butler and Cuyahoga in Ohio; Allegheny, Dauphin and Philadelphia in Pennsylvania; and Bexar County in Texas.
