News Journal: Delaware's air gets an 'F' for ozone

Delaware's air quality, while improving over the last two decades, still gets a failing grade throughout the state because of high levels of ozone on hot and sunny days. And in northern Delaware, particulates are still high enough that the state received a C on the American Lung Association's newly release State of the Air report. That's an improvement from 2014, when New Castle County was barely passing with a D, but experts say those particles still negatively impact health outcomes.

"Delaware can certainly be proud of the progress we've made in cleaning up our air since the first 'State of the Air' report 16 years ago," said Deborah Brown, President and CEO of the American Lung Association of the Mid-Atlantic. "However, there's still a lot of work to be done to make our air healthy for all of us to breathe.

"We can thank cleaner diesel fleets and cleaner power plants for the continued reduction of year-round particle pollution. However, the persistent problem of unhealthy days of high ozone continues to be a struggle for Delawareans, especially for those with lung disease, like asthma or COPD."
