The areas also include prominent urban cities and localities such as Los Angeles, San Diego, Denver, Salt Lake, Sacramento, as per the research report.

According to recent data, a staggering 131.2 million Americans, which translates to two in five individuals, reside in cities with failing air quality grades. Among these cities, thirty received failing grades specifically for ozone and particle pollution.

Adding to the concern are the 30 counties scattered across the country that received failing grades for both ozone pollution and small particle pollution, encompassing daily levels as well as annual exposure. Surprisingly, merely 98 metropolitan areas managed to secure passing grades for ozone pollution, while only 55 metropolitan areas attained passing grades for short-term particle pollution.


The bulk of failing grades for air quality are concentrated in Western states, with California bearing the brunt of the burden. Specifically, California accounts for 22 out of the 30 counties that received failing grades across all categories.
