A total of 156 million residents in the US, approximately 46% of the population, resided in areas with poor air quality that received an “F” grade from the American Lung Association due to ozone or particle pollution. This indicates a decline in the country’s air quality standards, as per the Association’s 26th Annual Air Quality Data Analysis.
An examination of data from 2021 to 2023 revealed a rise of about 25 million individuals living in unhealthy environments compared to the previous year’s survey results.
The report highlights the impact of climate change, such as increased heat, drought, and wildfire smoke, contributing to changes in air quality nationwide.
Katherine Pruitt, senior director of Clean Air Policy, expressed surprise at the significant increase in the number of people residing in areas with poor air quality, especially due to ozone degradation. She emphasized the influence of hot and sunny weather conditions on this deterioration.
In 2023, the final year of the Lung Association’s analysis, global temperatures recorded by the National Oceanic and Atmospheric Administration were among the highest on record. The US experienced the fifth-highest temperatures in its history.
The spike in ozone levels, particularly in states like Texas facing intense heatwaves in 2023, was evident. Pruitt pointed out how towns like Del Rio endured temperatures exceeding 100 degrees for extended periods.
Additionally, heavy wildfire smoke significantly impacted air quality, with regions like the northeast being exposed to the most smoke in modern American history due to wildfires in Canada.
The growing threat of wildfire smoke has hindered progress made under the Clean Air Act, releasing particles that pose health risks. Recent studies indicate that around 25% of Clean Air Act progress has been reversed due to increased wildfire smoke.
Pruitt warned of ongoing environmental degradation and its consequences, emphasizing the need to address emission sources to combat these challenges.
The EPA’s plans to roll back environmental regulations, including revisiting programs under the Clean Air Act, have raised concerns about future air quality standards.
Bakersfield, California, was identified as having the most polluted air in the country from 2021 to 2023, ranking high for both short-term particle pollution and ozone pollution.
