Seven of the country’s 10 most air-polluted cities are in California, despite the state’s strict environmental laws, according to a new American Lung Association (ALA) study and reported April 24, 2019 in The Hill.
Los Angeles ranked as the most smog-filled metro area in the ALA’s annual State of the Air report. The city has occupied the top spot for 19 of the 20 years that ALA has compiled the rankings. Other Golden State cities in the top 10 are San Diego, San Francisco and Sacramento.
The only metro areas on the most-polluted list outside California are Houston, the New York City region and Phoenix.
The ALA report also found that ozone pollution has worsened across the country, with 17 of the 25 most ozone-polluted cities measuring more high ozone days on average from 2015 to 2017 than 2014 to 2016. Ozone pollution is particularly high in cities in the West and Southwest.
Of the 25 most ozone-polluted cities, 10 are in California, with three in Texas: Houston, Dallas-Fort Worth and El Paso. Colorado has two — Denver and Fort Collins — while Arizona, Nevada and Utah each appear once on the list. Seven cities east of the Mississippi River are on the list.
Only six metro areas recorded no days when smog or short-term soot pollution was at an unhealthy level: Melbourne, Fla.; Bangor, Maine; Burlington, Vt.; Wilmington, N.C.; Lincoln, Neb.; and Honolulu.
