RALEIGH, N.C. -- A report that describes the air quality for cities in the country reveals that in 2018, Durham and Chapel Hill had higher than normal ozone levels for 90 days. That same report shows that Raleigh had 75 such days.

The group, Environment North Carolina, discussed the report during a press conference on Wednesday. The group says a high number of vehicles on the highway is one of the big reasons for potential pollution problems.

They encouraged consumers to think about buying more electric vehicles since they do not rely on fossil fuels.

Environment North Carolina also says there could be a harsh impact on people with health problems. 

 "I don't have to tell you that North Carolina gets hot in the summer. And it's only going to get hotter. And when you think about children with asthma having asthma attacks, that's only going to get worse," Jamie Lockwood with Environment North Carolina said.

Although the Triangle had a few high days, the area does compare favorably to other cities. The report says that San Diego, Los Angeles, and Pheonix all had elevated levels of ozone for more than 150 days in 2018.
