More than 137 million Americans, representing over 40 percent of the U.S. population, are living in places with failing grades for unhealthy levels of particle pollution or ozone, according to the “State of the Air” 2022 report from the American Lung Association.
The report measured three types of pollution—ozone pollution, short term particle pollution, and annual average year-round particle pollution. Particulate matter pollution, technically called PM2.5, can result in several health issues like strokes, lung cancer, heart attacks, asthma attacks, etc., while ozone pollution can result in coughing, shortness of breath, and so on.
In its 2007 report, 136 counties from 36 states had received failing grades for spikes in air pollution. This included 31 counties in seven states lying west of the Rocky Mountains. In 2022, 96 counties in 15 states got failing grades, of which 86 were from 11 western states.
“In 2007, 73 counties in 18 states got failing grades for annual particle pollution, and all but 8 counties in California and one in Montana were east of the Rockies. In 2022, all of the 21 counties that got a failing grade for annual particle pollution were in five western states.”
Of the top five cities most polluted by short-term particle pollution, four were in California—Fresno-Madera-Hanford, Bakersfield, San Jose-San Francisco-Oakland, and Redding-Red Bluff.
All the top five cities in terms of year-round particle pollution were from California. When it came to ozone pollution, four of the top five cities were also from California, with the fifth being Phoenix-Mesa, Arizona.
Some of the cleanest cities were Bangor, Wilmington, Charlottesville, Lincoln-Beatrice, Urban Honolulu, Virginia Beach-Norfolk, and Burlington-South Burlington-Barre.
According to the report, 122.3 million people were living in counties that received the lowest F rating with regard to ozone pollution. 63.2 million people lived in counties with an F rating for short-term 24-hour PM pollution while 20.3 million lived in counties that received a “Fail” rating for annual PM pollution.
The report found demographic variations in the groups which are at the highest risk of being exposed to pollution. Around 31 million children under the age of 18 and almost 21 million adults over the age of 65 were living in counties with an F grade for at least one pollutant. Around 4.7 million children and 2.8 million seniors lived in counties with an F grade in all three pollutant measures—ozone, 24 hour PM, and annual PM.
Millions of people suffering from health conditions like asthma, cardiovascular disease, and chronic obstructive pulmonary disease (COPD) were living in counties with a grade F for at least one pollutant. Among those with lung cancer, over 66,000 people lived in these regions as of 2018. The report called on the White House and Congress to take steps to reduce air pollution.
“EPA (Environmental Protection Agency) must set stronger standards for greenhouse gas emissions for light-duty vehicles beginning in Model Year 2027. EPA must finalize a strong rule for heavy-duty vehicles this year and adopt an additional rule beginning in Model Year 2030,” the report said while also asking the agency to set a “stronger national standard” for particulate matter and ozone.
