Air quality in some parts of US worst in 25 years, report says

About 44 million Americans live in cities or counties that received a failing grade for air quality, which has deteriorated to its worst in 25 years across a swath of the U.S., in part because of wildfires, a report released on Wednesday found.
The American Lung Association’s annual “State of the Air” report said cities with the poorest quality air are concentrated in the West, including Los Angeles and San Bernardino in California and Phoenix, Arizona.

Among the places with the highest quality air are Bangor, Maine along with Honolulu, Hawaii, and Wilmington, North Carolina, where ocean breezes tend to disperse pollutants, the report’s author Katherine Pruitt, a senior director with the association, said in an interview.
“Dangerous pollution has serious health effects for all people, but especially for the vulnerable,” she said.
The report was based on 2022 data – the most recent available – collected through thousands of air quality monitors set up by the U.S. Environmental Protection Agency.

Despite the deterioration in some areas, air quality in the U.S. is far better than it was before the Clean Air Act was passed in 1970, Pruitt said. Gone are the days where the Los Angeles skyline was often obscured by smog.
“Cars have gotten cleaner, fuel is cleaner, the dirtiest power plants have been shut down.”
But the steady improvement stalled about 2017, Pruitt said, partly because of smoke from wildfires, which have plagued California and other U.S. states, as well as Canada, in recent years.
