While air quality has improved, there is a continued increase in unsafe spikes in particle pollution that is putting Americans' health at risk, according to the American Lung Association's 2017 State of the Air report.

The ALA's "State of the Air 2017" report analyzed air pollution data collected by the EPA from 2013 to 2015 and found that 125 million people live in counties that have unhealthful levels of either ozone (smog) or particle pollution.

While the number of days that the Bay Area as a whole experienced unhealthy levels of particle pollution is not contained in the report, the region is listed as being the nation's sixth-worst for short-term spikes in particulate matter and fourth-worst for year-round totals.

Charleston-North Charleston was joined by Columbia-Orangeburg-Newberry and Florence among the cleanest cities in the region for ozone.

Those findings are contained in the American Lung Association's annual State of the Air report, released Wednesday.

Billings also stated most regions of the United States enjoy better air quality than existed a decade ago but added a multitude of metropolitan areas are still experiencing their highest of unhealthy air pollution days since the report first began publishing 18 years ago.

Kern County received failing grades by the lung association, Sadredin said, but so did coastal cities such as San Luis Obispo, Santa Cruz and even Hawaii.

• Continued setbacks in the fight against particle pollution (also known as soot), especially in the San Joaquin Valley.

Ozone, meanwhile, forms when pollutants emitted by cars and other sources react with sunlight.

Now the Lung Association is pairing with Milwaukee County's fire departments, which will fly flags so residents get a daily assessment of air quality.

Only Los Angeles was worse for ozone pollution, brought on by things like emissions from trucks. The Detroit-Warren-Ann Arbor area was the only MI market to make the dirty list, coming in at 18th worst for year round particle pollution.

Children and people over the age of 65 are the most at risk of having serious health issues like asthma attacks and other lung diseases.

"As a result, Americans' lung health is far better protected today than it was before the Clean Air Act health protections began almost five decades ago". He says all cities have reduced pollution and smog.

Almost four in 10 people live in a city where pollution levels are too unsafe to breathe.

High levels of pollution can trigger asthma attacks, heart attacks and strokes.

In California and nationwide, the number of unhealthy days for ozone has decreased, thanks to the success of the federal Clean Air Act as well as state and local air pollution control programs that clean up major sources of emissions.

Niagara County recorded a pair of high-ozone days over the same three-year period. And Lincoln and Beatrice are ranked as two of the cleanest USA cities for ozone air pollution.

The report is a combination of good and bad news; year-round pollution has improved however, short-term spikes of intensely polluted air have increased.
