Forecasters have predicted Code Orange conditions, which means that air quality in these areas is likely to be unhealthy for sensitive groups. People who are sensitive to air pollution should avoid moderate exertion outdoors. Sensitive groups include: children and older adults; people who work or exercise outdoors; people with heart conditions; and those with asthma, bronchitis, emphysema and other respiratory ailments.
The primary pollutant of concern is ozone, a highly reactive form of oxygen. Ozone can be unhealthy to breathe, and high levels generally occur on hot sunny days with stagnant air.
The air pollution forecast for Thursday predicts that ozone levels in the Triad, Charlotte and the Triangle will exceed the federal standard of 75 parts per billion averaged during eight hours. High ozone levels can impair breathing and aggravate symptoms in people with respiratory problems and irritate the lungs in healthy individuals. People with chronic lung ailments, older adults and children should reduce physical exertion and outdoor activity in the afternoon, when ozone levels are highest.
In addition, residents of affected areas should refrain from outdoor burning on Code Orange and Red days.
