Unhealthy air pollution affects a third of Americans

 Axios - Unhealthy air pollution levels affect more than a third of U.S. residents, Axios' Rebecca Falconer writes from an American Lung Association report. The number of people facing "daily spikes in deadly particle pollution was 63.7 million, the most reported in the last 10 years." The report underscores disparities in the U.S., with people of color accounting for 54% of the nearly 120 million Americans living in counties with unhealthy air pollution levels.
