Los Angeles Tops U.S. Cities in Poor Air Quality, Report Finds

The American Lung Association's latest report highlights significant air pollution issues across the U.S., with Southern California cities leading in ozone and particle pollution.

Los Angeles, Bakersfield, and Fresno rank highest for ozone and particle pollution, according to the American Lung Association.
Nearly 40% of Americans live in areas with failing air quality grades, particularly affected by particle pollution.
Particle pollution is linked to severe health risks, including cardiovascular and respiratory diseases, and brain damage.
West Coast cities, heavily impacted by industry and wildfires, dominate the list of areas with the worst air quality.
Cities with the cleanest air, like Bangor and Honolulu, generally have lower population densities and less industrial activity.
