Craft also noted the environmental policies of the Trump administration, which continue to roll back a range of protective measures, include loosening regulations on air pollution. The area also ended up at No. 17 for "short-term particle pollution".

Seven million more American now live in counties with unhealthy, polluted air than did a year ago, according to a new report.

The report states that California has seven of the ten most ozone polluted cities in the United States, with Los Angeles being the top (LA had almost 120 days in which ozone was above the healthy limit). The American Lung Association says both forms contribute to asthma attacks, heart attacks and lung cancer. That's the type of pollution caused by coal-fired power plants, diesel and wildfires. Lane County experienced a significant increase in unhealthy particle days and received an "F" grade in the report.

The country as a whole recorded more days with hazardous air quality than ever from 2015 to 2017, the researchers said, defined as air that reaches "emergency conditions" on the government's air quality index.

California claimed seven of the top 10 most ozone-polluted cities, with Los Angeles topping the list for the 19th time.

And it can be damaging especially for people living with lung disease.

"As we have more people in the city driving more solo trips, that equals more ozone", Penrod said.

In Denver and around the world, ozone pollution is being made worse by climate change.

Climate change brings higher temperatures, drought, floods, wildfires and other extreme weather that makes it harder to breathe and makes pollution worse. "It's like getting a sunburn on your lungs".

Each year the "State of the Air" provides a report card on the two most widespread outdoor air pollutants, ozone pollution, also known as smog, and particle pollution, also called soot.
