Burning fossil fuels through cars and coal plants is exacerbating the presence of ground-level ozone gas in the air we breathe. The gas has been linked to negative effects on pulmonary health, but a new study from Duke University shows ozone may have serious consequences for heart health as well.

The Department of Environment and Natural Resources is recommending that vehicle emission testing is no longer necessary in many North Carolina counties. 

The DENR report, ordered by the Legislature in 2013, says that emission testing of cars and trucks in as many as 31 counties could be eliminated by next year. 

Ozone Levels Lower

Oct 31, 2011

State health officials say fewer emissions from cars and industrial buildings cut down on air pollution this year. The annual ozone season officially ends today. There were 26 days in which ozone exceeded healthy levels. That's well below the 10-year average of 41 days. Division of Air Quality spokesman Tom Mather says recent numbers are lower despite back-to-back hot and dry summers.

UNC Research Points To New Ozone Standard

On warm days like today, pollution in the air can produce excess ozone near the ground. And air quality officials often issue ozone alerts - warning people with breathing problems to reduce activity or stay indoors.  But new research from UNC indicates the current acceptable ozone levels established by the Environmental Protection Agency might actually be too high.
