The American Lung Association has released its latest study on air quality across the United States.
Among the concerning findings for the state are the high levels of pollution and ozone in Maricopa County.
JoAnna Strother, senior director of advocacy with the association, spoke on PBS’s “Arizona Horizon.”
“Maricopa County, again, getting an F grade. We see more days when we have high days of particle pollution," Strother said.
Pima County also received poor grades for its air quality.
However, Flagstaff was listed as one of the cleanest cities due to its low ozone air pollution.
Strother also said climate change affects efforts to clean up air pollution.
