COLUMBIA — South Carolina environmental officials are issuing forecasts for ground-level ozone in the state.

The Department of Health and Environmental Control says the forecasts for how ozone levels will affect air pollution began Sunday.

DHEC’s Bureau of Air Quality Chief Myra C. Reece says ground-level ozone is South Carolina’s most widespread air quality problem during warmer months. She says levels are the highest on hot, sunny days when there isn’t much wind.

High levels of ground-level ozone can cause breathing problems, especially in children or people with respiratory problems and can damage trees and crops.

The forecasts can be found at DHEC’s website at www.scdhec.gov/ozone.
