According to data collected by the Environmental Protection Agency, prior to COVID-19, one in four Americans lived in counties with poor air quality,
While COVID-19 brought lockdowns that resulted in better air quality due to decreased commercial activity and car traffic, the recent surge of fires has the ability to quickly reverse this trend, once again exposing Americans to poor air quality.
Ozone-related pollutants are the most common cause of poor air quality, many Americans are also exposed to a variety of other common pollutants such as particle pollutants, sulfur dioxide, and lead.
Through the passage of the Clean Air Act, the U.S. has seen improvement in air quality and a decline in the emissions of common pollutants since 1970. CO2 emissions have also shown small declines since 2010.
Still, air quality in many areas, especially in the Western U.S., does not meet national standards.
