N.C. officials issue Code Orange alert

RALEIGH – Air quality officials issued a health notice today for air pollution in the Charlotte and Triad metropolitan areas on Tuesday. Forecasters have predicted Code Orange conditions, which means that air quality in these areas is likely to be unhealthy for sensitive groups, a news release said.

The Code Orange forecast means people who are sensitive to air pollution should avoid moderate exertion outdoors in the afternoon. Sensitive groups include children and the elderly who are active outside, people who work or exercise outdoors, 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, damage plants and reduce crop yields. High ozone levels generally occur on hot sunny days with stagnant air, when pollutants such as nitrogen oxides and hydrocarbons react in the lower atmosphere, the release said.

The air pollution forecast for Tuesday predicts that ozone levels will exceed the new federal standard of 0.075 parts per million (ppm) averaged over 8 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, the elderly and children should reduce physical exertion and outdoor activity in the afternoon, when ozone levels are highest.

The N.C. Division of Air Quality issues daily air forecasts for the Triangle, Charlotte, Asheville, Hickory, Fayetteville and Rocky Mount metropolitan areas. In the Triad, forecasts are issued by the Forsyth County Environmental Affairs Department. The forecasts are part of the N.C. Air Awareness Program, a voluntary effort aimed at reducing air pollution in the state’s major metro areas.  If you drive, avoid idling for long periods of time, stay within speed limits, combine errands to reduce the number of small trips, and use vehicles with higher fuel economies, the release said.
Conserve electricity by setting thermostats at the highest comfortable temperature and turning off appliances that are not in use.
In addition, residents of affected areas should refrain from outdoor burning on Code Orange and Red days.  It is always illegal to burn paper, trash, construction materials and other non-vegetative matter in North Carolina.
